(II) Suppose that the U-shaped conductor and connecting rod in Fig. 29–12a are oriented vertically (but still in contact) so that the rod is falling due to the gravitational force. Find the terminal speed of the rod if it has mass m = 3.6 grams, length l = 18 cm , and resistance R = 0.0013 Ω. It is falling in a uniform horizontal field B = 0.060 T. Neglect the resistance of the U-shaped conductor.

I have a physics question as follow "Consider the apparatus shown below in which a conducting bar can be moved along two rails connected to a lightbulb. The whole system is immersed in a magnetic field of magnitude B = 0.340 T perpendicular and into the page. The distance between the horizontal rails is ℓ = 0.800 m. The resistance of the lightbulb is R = 51.4 Ω, assumed to be constant. The bar and rails have negligible resistance. The bar is moved toward the right by a constant force of F = 0.600 N. We wish to find the maximum power delivered to the lightbulb.(a) Find an expression for the current in the lightbulb as a function of B, ℓ, R, and v, the speed of the bar.(b) When the maximum power is delivered to the lightbulb, what analysis model properly describes the moving bar?(c) Use the analysis model in part (b) to find a numerical value for the speed v of the bar when the maximum power is being delivered to the lightbulb.(d) Find the current in the lightbulb when maximum power is…
A proton is located on the Earth's magnetic equator at an altitude of 1.0 km. In which direction will it be deflected when it is propelled vertically upwards away from the Earth's surface?
-East, Upward, Downward or West? Why?
(I) A single square loop of wire 22.0 cm on a side is placed with its face parallel to the magnetic field as in Fig. 20-34b. When 5.70 A flows in the coil, the torque on it is 0.325 m • N. What is the magnetic field strength?
