Two identical objects go around circles of identical diameter, but one object goes around the circle twice as fast as the other. the centripetal force required to keep the faster object on the circular path is 1. four times as much force as required to keep the slower object on the path. 2. half as much force as required to keep the slower object on the path. 3. one fourth as much force as required to keep the slower object on the path. 4. twice as much force as required to keep the slower object on the path. 5. the same force required to keep the slower object on the path.

Athin plate moves between two parallel, horizontal, stationary flat surfaces at a constant velocity of v = 7.5 m/s. the two stationary surfaces are spaced 4 cm apart, and the medium between them is filled with oil whose viscosity is 0.9 n·s/m2. the part of the plate immersed in oil at any given time is 2 m long and 0.5 m wide. if the plate moves through the mid-plane between the surfaces, determine the force required to maintain this motion. what would your response be if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top surface (h1)? if the plate moves through the mid-plane between the surfaces, the force required to maintain the motion will be n. if the plate was 1 cm from the bottom surface (h2) and 3 cm from the top (h1) surface, the force required to maintain the motion would be n.
