What is the emf of the coil? A 1000-turn coil of wire 2.20 cm in diameter is in a magnetic field that increases from 0 T to 0.130 T in 12.0 ms . The axis of the coil is parallel to the field.

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

The radius of a sphere is increasing at a rate of 9 cm/ sec. find the radius of the sphere when the volume and the radius of the sphere are increasing at the same numerical rate.

Ball bearings are made by letting spherical drops of molten metal fall inside a talll tower-called a shot tower- and solidify as they fall. a-if a bearing needs 4.0 s to solidify enough for impact, how high must the tower be? b- what is the bearing's impact velocity?
