Factor of k for air is 8.93x10(power)9 Nm(power)2/C(power)2 Calculate force between charges of +150.0(micro)C and -75.0(micro)C that are 0.600 m apart in air. * I am not able to use the proper symbols for (power), or (micro)
Imagine in a remote area of the countryside a 70-kV, 60-Hz power line. A shifty local resident has erected a large open loop just below the line with the intention of drawing power. Is this possible and, if so, how would it be transferred? Where would the energy stolen come from? Would anyone be able to detect the loss? Might it
Multiple choice: 1. An ideal source of emf is connected in series with a resistor in closed loop, and a current or 0.e50 A circulates. An additional 6.0-Ohm resistor is added in series, and the current drops to 0.30 A. The original resistance was: (a) 9.0 Ohm (b) 6.0 Ohm (c) 15 Ohm (d) 3.0 Ohm (e) none of these. Explain your ch
Consider a rectangular loop of length l (parallel to x) width w (parallel to y) total resistance R, is being pulled at constant force F=fx. If at tiem t=0 it is aligned with the front edge at x=0, has velocity vx, and the magnetic field everywhere is B= 0 x<0 B= BoZ x>0 solve and draw plots for the time dependence of:
