Hi I am having trouble relating power to the electric field amplitude, I know that P=IA and E=cB, could someone please help? The problem reads:
What electric-field amplitude is required to transmit an amount of power equal to that handled by modern transmission lines (that carry voltages and...
u X v, but what is u and what is v in the formula? ((3.11 x 10^4)*(1.63T)) - ((3.11*10^4)*(0.980T)) = (2.02*10^4), so ((2.02*10^4)(1.22*10^8))/(1.81*10^-3) = acceleration... Is that right?
Hi I need help finding what the acceleration is for the following problem: A particle with a mass of 1.81x10(-3) kg and a charge of 1.22 x 10(-8) C has at a given instant a velocity v=(3.11 x 10(4) m/s)j. What are the magnitude and direction of the particle's acceleration produced by a uniform...
A coil is to be used as an immersion heater for boiling water. The coil is to operate at a voltage of V and is to heat an amount of water with a volume of v by T degrees C in a time interval of t seconds.
Use 4190 for the specific heat capacity of water and 1000 for the density of water. How...
Suppose that a person has a resistance of 13.0 kiloohms as part of a circuit which passes through his hands. This person accidentally grasps the terminals of a power supply with a potential difference of 16.0 V.
PART A:If the internal resistance of the power supply is 2100 ohms , what is the...

In this one problem I am given I=3.20A, L=4.2m, cross-section=.00220m, n=8.85*10^28, and e=1.6*10^-19.
I am using an equation that is set up like this to find the t=((l*w)*n*q*L)/I
When I calculate ((0.00220m)^2*(8.85*10^28)(1.6*10^-19)*(4.2))/(3.2) I get 8.99*10^4 and for some reason the sig...
Capacitor Problem!
Hi I have a problem where the applied potential is V_ab, Capacitors C1 and C2 are in parallel, and the combination is in series with C3. Now I'm trying to find the charge q1 on the capacitor C1. I thought that q1 = V_ab*((C3*C1*C2)/(C3 + C2+ C1)), but it is wrong. Can someone...
Two stationary point charges and +3.00*10^-9 C and +2.00*10^-9 C
are separated by a distance of 50.0 cm. An electron is released from rest at a point midway between the two charges and moves along the line connecting the two charges. What is the speed of the electron when it is 10.0 cm from...
Thank-you so much for your help! I have a part 2 of the problem that says "A point particle with mass, m, and negative charge, -q, is free to move along the x-axis (but cannot move off the axis). The particle is originally placed at rest at and released. Find the frequency of oscillation of the...
