Open Question: Can answer this question about running for me? (please read)?

okay, so i just bought some running shoes cause i want to start running, eventually making my way up to 5 and 10ks. I talked to one of the guys at the store, and they said that for 2 weeks, i should run monday, wednesday, and friday for 30 minutes and then after 2 weeks i should do monday 30 min, wed 45 min, and fri 30 minutes and then eventually work my way up to 5 days a week. But right now, with school and everything, i don't really want to run for that long. I'm aware that i have to build up my endurance, but i'm in pretty good shape. I was mainly thinking of just starting with HIIT method, but they said that that was a bad idea to start with. I would only do it for like 10-15 minutes 3 days a week, but i guess i don't really know exactly what it all involves. He also said that i should do like sprints for speed with about 400 meter distances, but i don't have acess to a track and my neighborhood is pretty much just one big hill. What can i do and should i start out with HIIT. I mainly want to run to get my abs more defined. Would doing the guy i talked to routine work better for my abs along with ab exercises, cause i can already see my six pack, i just want it more defined. What is the best way of going about doing this? more

Open Question: Does this reading show that i have diabetes?

today i finally got a blood glucose meter to test my blood sugar. I got the meter from a friend at work whose husband has diabetes. I measured it about 45 min after eating, but it was only so she could show me how it worked before she went home. For lunch i had 4 chicken tenders with breading, honey mustard and sweet baby rays sauce, and a root beer can of soda. my reading said my blood glucose was 234mg/dl I know your suppose to wait 2 hours before testing it when eating a meal...but is that a normal range for the time elapsed? if your a diabetic, this would also help. thank you.. more

Resolved Question: Can anyone recommend me a camera?

It's for my photography class. I needs to be a 35mm, with options for manual aperture, manual shutter speeds, and manual ISO/ASA settings. It also needs an internal metering system. I also need a 45 - 55 mm lens (I'm not sure if that is purchased separately or if it should be part of the camera). I know what some of that means but I just don't know how I can make sure the cameras I'm looking at online have all of that. I want to make sure if I'm going to shell out $200 for a used camera that it comes with all the stuff I need. The professor informed us on the first day of class that this purchase needs to be made so I'd like to get it ASAP. I'd like the names of some cameras fitting this description. Links to cameras that I can purchase would be even better. I really appreciate your help.I was looking at this one. http://cgi.ebay.com/Nikon-FM10-35mm-Film-Camera-body-only-/200447349421?pt=Film_Cameras&hash=item2eab97d2ad It lists a lot of the details and I see that there's a manual option for all the things I needed to be manual so that's good. I'm just not sure if I need to buy a separate lens or if I can make due with whatever it comes with. Because I looked up the lenses it would take and they're way expensive (but then again I may not be looking at the right thing). more

Resolved Question: first problem of the day and I'm having trouble already?

The problem is : The tires of a car make 65 revolutions as the car reduces its speed uniformly, from 95km/h to 45 km/h . The tires have a diameter of .08 m. part a) what was the angular acceleration of the tires ? part b) if the car continues to decelerate at this rate how much time more does it require to stop? The answer in the back of the book is: -4.1 rad/s^2 for a) and 7.6 s. for b) I used the formula: initial angular speed (Onega)=Vo/r for both 95km/h and 45km/h after connerting them to meters per second. and then I was going to use angular acceleration( alpha)=Omega^2-initial Omega^2/2 theta. I calculated theta as 65 rev times 2pi. , I think that may be my mistake , but it's not clear to me form my reading , on how to calculate theta. Or am I taking the complete wrong approach? thanks for any help, I have a test tomorrow and I'm trying to work out as many problems as possible. more

Open Question: Poor Battery Notification on My Laptop?

Hello I have an Acer Aspire and use Windows 7. From time to time I just want to use my laptop's battery so i don't keep it plugged in too often (battery life precaution). My notifications are on, i have set up a sound, low battery level is 30% critical battery level is 5 or 10... I got notifications a couple of times after i chose those settings, but after that-no alarm, just hibernating without a notice. And it is driving me crazy :D I was watching my battery meter and it showed 45% and i was waiting for the 30% alarm but it never reached 30-hibernated at 45. Probably my battery is already going to heaven, but if you have any solutions or advice i would be glad to read them. Thanks more

Open Question: could i break my goal times?

so i am 14 and a boy, and freshman in high school now. i am doing xc for the first time and first meet was last wednesday, i got 21:54. bad time considering my other times are 2:22 for 800 meter, and 5:45 for the mile(may be faster now cause i have been doing xc for a while). it may be that i am new to xc and not used to it. people say i could break 19 min at end of the season, but right now i am trying to break 21 in the meet tomorrow. the course is flatter than the course last week that had a big hill that we had to go up twice and 2 smaller ones that we had to up 4 times. will i be able to get under 21 or even 20 tomorrow? is it possible to break 19 by the end of the season? i work hard, but when i get tired and legs hurt, i have tendency to slow down. it may be that i am new to xc.i have done track for middle school for 2 years and the most i have run was like 5 miles. i did 4x800 and mile and 4x400 in 8th grade year. also goals to break by end of freshman track:800: 2:15 or under. mile/1600: 5:20 or under more

Resolved Question: My suggestion of sprint training?

I was wondering, i had an idea of sprint training in mind cus i cant decide whcih ones i shood do in yahoo answers, so i've decided to do all of them. now i need u guys to tell me if i can imrpove it anyway, make it stay the way it is, or decrease just some of the workouts. (I do all these per day) here goes: -600 squats starting out, increasing it by 100 each week, raising the pounds by 5 each week on each hand doing 20 reps each, 30 second rest. -20 sets of 20 reps hill runs up and down (the up will only count as 1 not up and down) for about 5 meters back and fourth, the hill is about an angle of 45 degrees or less. 20 second rest after each set -100 rocket jumps -10x 100meter sprints. 30 second rest after each sprint Upper body training: -200 pushups, -100 scissor work outs -200 weight lifting on each hand increasing it by 5 pounds each week. Additional info: im 14, i weigh 95 pounds, I had experiences with training from all these, just not all together, i did them separated. Let me know if i can imrpove it , becuase i really want to beat usain bolt, its my dream, thats why i train for sprinting, and i told many of my friends i'd be in the olympics so i dont wanna disapoint them, and for the upper body, the reason for that is becuase i want to protect my friends (long story) basicaly fight happend, almost lost, wanted to be prepared for next time if there is gonna be 1 again, for self defence.Also my best time for 80 meters was 9.4 seconds, so i calculated it to be 11.75 for 100 meters. more

Resolved Question: Speed and Velocity Problems: Help!?

I already have the answers for some of the problems, I just need to know how to work it. I will need to know the answers for some of the problems and the work. Thank you! 1) Matt is traveling along a straight interstate highway. He notices that the mile maker reads 260. He continues to travel until he reaches the 150 mile marker and then retraces his path to the 175 mile marker. The distance traveled is 135 miles (I figured this out) a) What is his displacement from the 260 mile marker? b) If he accomplishes the trip in 30 minutes, what is his average speed in miles per hour? 2) Georgia runs a 100 meter race with a time of 10.75 sec and a 400 meter race (a complete time around the track) in 42.3 sec. In which case is her velocity the greatest? (there is distant difference between speed and velocity) 3) Phil Fiziks is driving down a street at 55 km/h. Suddenly a puppy runs into the street. It takes Phil 0.75 sec to react and apply the brakes. How many meters will he move before the car begins to slow? Answer is 11m 4) A car's position is recorded at 1-sec intervals and recorded in the data table like the one below. What is the car's average velocity between 4 and 5? Interval: 1, 2, 3, 4, 5, 6 Time (s):0, 1, 2, 3, 4 5 Position:30,30,35,45,60,70 (in meters) (answer is 15 m/s) 5) A person walks 15km in 2.0h. What is the person's velocity in m/s? (answer is 21 m/s) 6) It is now 10:29am, but the bell rings at 10:30am, Mary will be late for French class for the third time this week if she does not get there on time. She must get from one side of the school to the other by hurrying down three different hallways. She runs down the first hallway, a distance of 35m, at a speed of 3.5 m/s. The 2nd hallway is filled with students, and she covers its 48m length at an average speed of 1.2 m/s. The final hallway is empty, and Mary sprints 60 m length at a speed of 5 m/s. Does Mary make it to the class on time or does she get dentention for being late again? If she is late, how late is she? If it already has an answer can you explain the work. :) more

Voting Question: Fluid force on a vertical plate submerged in water?

"Find the fluid force on the vertical plate submerged in water where the weight density of water is 9800N/m³" The vertical plate is a square, but it's rotated 45 degrees from the orientation that would have the edge parallel to the top of the water. (It's a "diamond" shape) The dimensions of the square are 3 meters by 3 meters and the depth from the surface to the top corner of the square is 1 meter How would I solve this problem using calculus? (What I want to see in an answer is how the formula w ∫ h(y)L(y) dy (From c to d) would be used where h(y) is depth as a function of y, L(y) is the horizontal length of the region at y, and w is the weight density (9800N/M³), and c is the lowest depth of the plate and d is the highest depth of the plate)To P: Please read the the question next time, everything you said was included in the question. and w IS a constant because the weight density of regular water will not be changing anytime soon more

Voting Question: pay water bill after we moved out?

I recently moved out of a rental home that I occupied with my husband for three years. We were responsible for paying our quarterly water bills which we paid on time for three years and it never once exceeded $66 for 3 months. We moved out mid July and the water meter wasn't read until mid August. Our landlord agreed that he would pro-rate the last month's bill so we wouldn't pay for the last month we weren't there. However, when we got the bill, it was $280!! Apparently, the workers who came to paint or clean the carpet must have left the water running during this last month and increased our water bill. We should not be responsible to pay for this water usage since it must have occurred after we moved out (when we handed over the keys, no water was running). One would expect our water usage during the last 2 months to be the same as it was for the entire 3 years we were living there. However, the landlord is requiring that we pay this huge bill and has deducted it from our security deposit refund. What can we do? We were expecting to pay approx. $45, not $280!!! This is in Baltimore City Maryland. Thank you.We contacted the city water works and they said the reading was accurate and that someone must have left the water running. We looked into small claims court, but after all the fees and time we wonder if it's worth it. We were just hoping there was something we could say or do to get our landlord to not charge us. We were legally out of the home and he selected and hired his own workers to paint and clean the carpet during the month we were gone and the water meter was running. He deducted it from our security deposit already.....ugh! more

Resolved Question: My truck after I got it out of impound!?

I got my 2007 Ford F-150 out of 30 day impound(110,000mi), why is my battery still weak after a week of driving it? Sometimes I even need a jump. The volte-meter odometer reads in the middle. I feel weary about going somewhere and parking and turning off the truck in fear of it not starting when I get back. Another thing is, the first day I got it out, It seemed like it wasn't getting enough gas, it was putting(putt putt) down the street like a junk car, and skipping like 5-10 times in a row real fast(my head was jerking back and forth)??? so I figured the fluids settled and just needed to drive the truck to get things moving again. Now the truck only sometimes skips around 45-50 mph and the putting went away. Any thoughts on the battery thing and why the truck still sometimes skips? (FYI, I changed the # 2 coil and #8 coil at dealer before, due to them misfiring, causing truck to skip) could this be that same problem again?, but just a different coil? any thoughts?check engine light is not on, but when I had to change the coils the first time, it wasn't on either.. more

Resolved Question: Working out combined uncertainties in equations: help!!!?

I have 2 situations and for both I have to work out the uncertainty: 1) The density (ρ = mass/volume) of Cu from a long cylindrical rod of pure copper measured with a metre ruler needs to be calculated. I am given the Length = 60 +/- 0.1 cm = (60x10-2 +/- 0.1x10-2) m, the Diameter = 0.632 +/- 0.002 cm = (0.632x10-2 +/- 0.002x10-2) m , the Mass = 162 +/- 1 g = 162x10-3Kg and the equation for the Volume (Pi* D^2 * L)/4 I have already worked out the Volume and the Density (no problem with those) BUT it's their uncertainties that are driving me bonkers! My question is since the Volume has D^2, do I need to incorporate uncertainty relations dX/X = n*(dA/A)= 2 * 0.002x10-2/0.632x10-2 = +/-6.329x10-3 then Sqrt((dA/A)^2 + (dB/B)^2) = Sqrt((6.329x10-3/0.632x10-2) + (0.1x10-2/60x10-2)) OR simply Sqrt((dA/A)^2 + (dA/A)^2 + (dB/B)^2) ??? Not sure?!? 2) The Local magnetic field strength which I have already found by rearranging a given equation must be calculated: B(coil)/B(local) = tanθ = (μ0*N*i)/(2*R*B(local)) where μ0 = 4pix10^-7 NA^2 (permeability of free space) R =(150 +/- 5)mm = (150x10-3 +/- 5x10-3)m, this is the radius N = 2, the nubmer of turns of wire around a rod i = (3.0 +/- 0.1) A, this is the current in Amps θ = (45 +/- 1)degree), this is the deflection of magnetometer hence giving me B(local) = (μ0*N*i)/(Rtanθ) I'm ok with re-arranging the equation and calculating the density but it's working out the uncertainties I'm confused about. I thought of the uncertainty relation Sqrt((dA/A)^2 + (dB/B)^2 + (dC/C)^2) where A=3.0, dA= 0.1 B=150, dB= 5 C=tan45=1, dC=1 Is that right or am I getting terribly confused?!? Can anyone shed some light please? more

Resolved Question: Do these symptoms mean anything?

Hi All, I'm 13, and I don't know why but I was experiencing these 'symptoms': 1. During 1 o'clock, the time I fell asleep, to 5 AM, I approx. woke up 7 different times, I was able to fall asleep after 20-45 minutes, but I wasn't sure if I was actually sleeping/dreaming because while I was awake I would hallucinate and while I was asleep I would continue my hallucinations. 2. One of the scenes from my dream was very vivid... It was just a couple of maggot on top of a old styled school chair. http://dhscientific.net/imgs2/chair.jpg 3.During the times I was awake. I kept seeing, hallucinating, a tall man, no facial features, just the outline on the wall in front of my bed. 4. This mostly happened during those random times that I woke up, I saw small white spiders forming webs from the wall next to me to my arms. I thought I felt some animals in my hair, I had the fan on, which later on I decided where maggots. Remember I had no control of my thoughts or what I saw. 5. Before I actually feel asleep. I went into the kitchen to get a glass of water, I had no lights on except the for tv in my room. For some reason, I thought I saw small children, maybe 4, completely dark and no features. Running from the kitchen to the living room... Which probably knocked up the paranoid/scared meter. 6. I was have a really hard time figuring out If I was asleep or or if I was awake. And that's about it ! I haven't been diagnosed with any sleep disorders, this was actually my first time experiencing these symptoms, I'm out of school, so I don't think it's stress. I just need some advice of what it can all mean. more

Resolved Question: Can you explain this?? Impaired glucose tolerance and low sugar?

I've been told I have impaired glucose tolerance for nearly 20 years. I've had gestational diabetes 3x. I don't understand it. Even when I was 16, if I had a regular breakfast (40g) of carbs, I'd fail the sugar test. Even when I was 25 and a size 2, I failed the test. It seems no matter what I do, my sugars go up. I watch what I eat, no fruit juice, simple sugars, limited carbs, VERY few desserts, etc. After I eat, even if the sugar doesn't go higher than 140, 3 hours later it plummets. I've had sugars in the 50's and 60's. I get sweaty, shaky, and B**chy. The lowest I've caught it on my meter is 48. If IGT is caused by reduced sensitivity to insulin, then why does it crash about 3 hours after I eat? It seems to me that my body puts the insulin in only after the sugar goes up. It seems like it lags behind. Can anyone explain this to me?? If I recall correctly, my recent A1c was 5.9. I had a Slim-fast shake this morning, and 2 hours later felt very hungry. I couldn't understand why. It dawned on me to test my sugar level and it was 181. The label says the shake had 30g of carbs (including the skim milk). I have a meter from my pregnancies. My mom has MODY for the past few decades, and it VERY ill from it. Her sugars are regularly 400-600. Last time she was hospitalized it was 1420. I don't want to end up like my mom. She is a brittle diabetic. My uncle, her brother, died at 45 from diabetes. My great grandmother was a Sioux indian. I moved to FL and the last endocrinologist I went to told me to not come back till all of my sugars were over 200. He also said that sugars in the 50's are normal when you diet. I think he is full of it. I had an endo at Yale that wanted to see me yearly, and now I can't find a doctor to see me. Advice??? The only time my sugar doesn't go up and I avoid a "crash" is with a meal with lots of protein, like bacon and eggs. But my last doctor got on my butt about too much fats and cholesterol. My HDL is sky high and my LDL is very low. I think the sugar issue is more important than cholesterol. My cholesterol is in the normal range and I eat approx.10-12 eggs a week. more
