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

Physics
124, thanks a lot, you the man. )

Physics
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?

Physics
it's correct ?

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

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

Physics
I think drawings at all identical so don't worry

Physics
prob 8

Physics
denaminator may be different, it depends on drawing

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

Physics
me, I will exchange solution 8 on 7)

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

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

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

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

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

Physics
10, b) how to solve

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!

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!

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

physics
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

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?

i am a 9-digit number. I have 5 in my hundred thousands place. The digit in my thousands place is 3 more than the digit in my hundred thousands place. The digit in my ten millions place is the sum of the digits in my hundred millions and hundred thousands places. The rest of t...

math
arrange the digits 1-9 by inserting plus or minus signs using each ditit only once to produce a total of 200

Refrigerator Suppose that you want to freeze 1.2 kg of water for a party, and only have 10 minutes to do it. Relying on nothing but your keen physical abilities, a dixie cup, duct tape and a piece of string, you manage to build a refrigerator unit which can do the job. The tem...

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 enough, he threw...

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