Just wanted to know if someone could help me out or check my answers. The Transformer 38) A step-down transformer is used for recharging the batteries of portable devices such as tape players. The turns ratio inside the transformer is 13:1 and it is used with 120V (rms) household service. If...

Just wanted to see if anyone could check my work. I only have 1 opportunity to do this. Thanks yall! 1.) Suppose that you wish to fabricate a uniform wire out of 1.00g of copper. If the wire is to have a resistance of R=.5Ω and if all of the copper is to be used, what will be (a) the length...

55) F = (2x10^5 N/C)(1.6x10^-19) - (9.8m/s^2)(1 x 10^-15) = 2.22x10^-14N a = 2.22x10^-14N/(1x10^-15kg) = 22.2m/s^2 Vf=(22.2m/s^2)(.075s) = 1.67 m/s upward Yf= .5(22.2m/s^2)(.075s)^2= .0624m = 6.24cm Thanks for the help! I appreciate it.

2 problems. I was just wondering if someone can help me start off the problem. The rest, I'll try to do because I don't know how to setup the problem. 55) A virus rests on the bottom plate of oppositely charged parallel plates in the vacuum chamber of an electron microscope. The electric...

19) An Olympic skier moving at 20m/s down a 30degree slope encounters a region of wet snow, of coefficient of friction, .74 a. How far down the slope does he go before stopping? I know the answer is 144m, but how do I get there? b. How much mechanical energy is lost in this process...

How am I supposed to figure out these concepts? No problems to do, but I'm just not understanding the material/concepts? anyone care to explain/teach me? 5.) Weight of a man who is throwing a bag of potatoes? 7/8) Net acceleration of a body on a curved path 10) Kinetic energy of a...

1.) A car rounds a banked curve where the radius of curvature for the road is R, the banking angle is 0(theta), and the coefficient of static friction is [mu]. (a) Determine the range of speeds the car can have without slipping up or down the road. (b) What is the range of speeds possible if R =...

Fnet= mass x acceleration mass is the same. how do i get the acceleration going up and down the plane??

I managed to figure out most of the problems! Thanks for the help. I'm still stuck on #6? Anyone have a clue to figure it out?

I have this take home test I'm doing for Physics. I did all the problems and was just wondering if someone can correct me if I'm wrong on any of the problems because I'm on the borderline B-/C+ and I could really use your guys' help to check the problems. Thanks a lot. **=not sure/dont know...

Geez, you should be my teacher. Your explanation in 6 lines taught me more than my teacher did in 3 class periods. Haha. Off to doing my work...

I'm stuck, for the past 30 minutes. Anyone care to give a struggling student a hand? Any help would be appreciated due to that fact that I don't understand the material. I have notes, yet I have one of those teachers who talk, but don't teach. I don't know. Thanks to anyone who can help me out...

Thanks for the help! I knew I had the answer, plugging in V to v totally slipped my mind.

1a) 1.0 x 10^-5 m/s^2 b) 1.0 x 10^-17 N On the 2nd problem I got stuck I set Mg(2 x l) and .5MV^2 equal. V^2=g(2 x l)/.5 = (g(2 x l)^1/2) / .5 After setting those two equations equal and solving for v in terms of V I got this. mv= MV + mv/2 mv-mv/2=MV mv(1-1/2)=MV mv(1/2)=MV...
