The kinetic energy of a man is half that of a boy whose mass is half that of the man. When the man speeds up by 5 m/s, his kinetic energy doubles that of the boy’s kinetic energy. What is the initial velocity of the man?
The mean kinetic energy of one mole of gas per degree of freedom (on the basis of a kinetic theory of gases) is ___________
A box contains 105 molecules. The average kinetic energy of each molecule is 0.5*10-6J. With respect to an observer at rest the box, having a mass of 1kg, is moving with a velocity of 2m/s. What is the value of kinetic energy that will contribute to the internal energy?
Kinetic theory of gases assumes that the collisions between the molecules are
Assertion: Oxygen addition in the control flow gases of solid rocket engine will result in a higher characteristic velocity of the exit jet. Reason: Because of secondary combustion, stagnation temperature and pressure increase. Higher stagnation temperature results in exhaust jet characteristic velocity.
According to kinetic theory of gases, the absolute zero temperature is attained when
