Please put the right answer and work out problem
thank you
A metal rod is forced to move with constant velocity = 55.0 cm/s along two parallel metal rails, connected with a strip of metal at one end, as shown in the figure. A magnetic field B = 0.45 T points out of the page. The rails are separated by 25.0 cm. What emf is generated If the rod has a resistance of 19.0 ohm and the rails and connectors have negligible resistance, what is the current in the rod At what rate is energy being transferred to thermal energyExplanation / Answer
Emf Generated E = B*l*v
E = 0.45 * 25/100 * 55.0/100 Volt
E = 0.0619 Volt
V = I*R
I = V/R
I = 0.0619/19 A
I = 3.25 * 10^-3 mA
Power = V*I
Power = 0.0619 * 3.25 * 10^-3 Watt
Power = 2.01 * 10^-4 Watt
Rate at which energy is getting transferred to thermal Energy = 2.01 * 10^-4 Watt
