A 150Ω resistor is connected to a coil with 30 turns and a cross sectional area of 0.02m2. A magnet is lowered as shown in the figure. The magnetic field increases from 0.01T to 0.06T in 20ms. Find the magnitude of the current going through the resistor. I = 0.1 A
I = 0.2 A
I = 0.01 A
I = 0.02 A
I = 0.001 A

pls answer :)

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Asolid cylinder and a cylindrical shell have the same mass, same radius, and turn on frictionless, horizontal axles. the cylindrical shell has light-weight spokes connecting the shell to the axle. a rope is wrapped around each cylinder and tied to blocks of equal masses that are held the same height above the ground. both blocks are released simultaneously. the ropes do not slip. which block hits the ground first? or is it a tie?
