Which of the diagrams in figure, correctly shows the change in kinetic energy of an iron sphere falling freely in a lake having sufficient depth to impart if a terminal velocity ?

A

B

C

D

Text Solution

Verified by Experts

(b) First velocity of the iron sphere increases and after sometime becomes constant called terminal velocity. Hence accordingly first KE increases and then becomes constant which is best represented by(b).

Two discs A and B are mounted coaxiallay on a vertical axle. The discs have moments of inertia I and 2 I respectively about the common axis. Disc A is imparted an initial angular velocity 2 omega using the entire potential energy of a spring compressed by a distance x_1 Disc B is imparted an angular velocity omega by a spring having the same spring constant and compressed by a distance x_2 Both the discs rotate in the clockwise direction.
