Question

Just need the answers in red. Thanks

In the figure, a metal rod is forced to move with constant velocity along two parallel metal rails, connected with a strip of metal at one end. A magnetic field of magnitude 8 = 0.466 T points out of the page. (a) If the rails are separated by 22.9 em and the speed of the rod is 53.6 cm/ s, what is the magnitude of the emf generated in volts? (b) If the rod has a resistance of 26.2 0 and the rails and connector have negligible resistance, what is the current in amperes in the rod? (c) At what rate is energy being transferred to thermal energy?

Explanation / Answer

b) V = IR

I = 0.057/26.2

= 0.002175 A

c)

P = IV = 0.002175*0.057

= 0.000124 W
