Statement-1 : For any collision, coefficient of restitution (e0 lies between 0 and 1. Statement-2 : This is because no collision may be 100% elastic or 100% inelastic.

A block of mass 5 kg moves from left to right with a velocity of 2ms^(-1) and collides with another block of mass 3 kg moving along the same line in the opposite direction with velocity 4 ms^(-1) . (i) If the collision is perfectly elastic, determine velocities of both the blocks after their collision. (ii) If coefficient of restitution is 0.6, determine velocities of both the blocks after their collision.

Which of the following option is correct for the given statements, 'X', 'Y' and 'Z'? Statements : Statement 'X' : R.Q. of fat containing palmatic acid is less than onc, whereas RQ of glucose is 1.

Two masses m and 2m are placed in fixed horizontal circular smooth hollow tube of radius r as shown. The mass m is moving with speed u and the mass 2m is stationary. After their first collision, the time elapsed for next collision. (coefficient of restituation e = 1//2 )

This question contains Statement -1 and Stantement -2 Of the four choices given after the statements, choose the one that best desctibes the two statemesnts. Statement -1: For a mass M kept at the center of a cube of side 'a', the flux of gravitational field passing through its sides 4piGM. Statement -2: If the direction of a field due to a point source is radial and its dependence on the distance 'r' from the source is given as (1)/(r^2) , its flux throught a closed surface depends only on the strength of the source enclosed by the surfcae and not on the size or shape of the surface.
