Trying to beat the heat of summer, a physics grad student went to the local toy store and purchased a child's plastic swimming pool. Upon returning home, he filled it with 154 liters of water at 25°C. Realizing that the water would probably not be cool en...

What is the angular momentum (in kilogram-meter^2/second) of a 500.0 g ball rotating on the end of a string in a circle of radius 1.54 m at an angular speed of 2.50 rad/s?

TRUE OR FALSE all mutations in a gene would have an effect on the protein encoded by that gene. please help! :)

A guitar string is 92 cm long and has a mass of 3.7 g. The length L from the bridge to the support post is 65 cm, and the string is under a tension of 570 N. What is the frequency of the fundamental tone thanks!

An organ pipe is 84 cm long and at a temperature of 20 degrees C. What is the fundamental (in Hertz) if the pipe is closed at one end thanks!

I've been trying that and I'm still not getting the right answer

thank you, but since it has to be in kg, do i do the same thing but with 0.5*1.54=0.77 0.5*0.77*2.50^2 = 2.406 kgm^2/s

10, b) how to solve

Anyone, can help with questions: 11 c) 10 b) 8 d,e,f) 5 b,d,e)

11 a) q/(4*pi*E_0*(r^2)*k) 11 b) q*k/(r^2) 11 d) 0

8 a) E = (st)/(S*E_0) S = Area 8 b) E*d 8 c) C = E*E_0*S/d

S = pi(b^2 - a^2)

Jack, did you solve anything else from this list: 11 c) 10 b) 8 d,e,f) 5 b,d)

me, I will exchange solution 8 on 7)

me, a = lambda/0.5 d = lambda/0.125

denaminator may be different, it depends on drawing

I think drawings at all identical so don't worry

11 b) q*9*(10^9)/r^2 r = distance from the origin

8 e) poling vector = E*B/mu_0 = ??

124, i have E and B correct but pointing vector with formula E*B/mu_0, mu_0 = 4*pi*10^(-7), incorrect. pliz, tell where is error?

124, thanks a lot, you the man. )

124, 11 c) - Could you please help and give any hints on it?

Sometimes the answers are not in the same order. 1. Starting to talk over the audience to quiet them down 2. Speaking quickly so you don’t bore ... 3. If a driver gets lost on the road, a GPS can be useful. 4. Twice a day, twenty-seven satellites... 5. Mo...
