If the number of molecular mass of a gas becomes half and velocity becomes doubled, then calculated the initial and final pressure.

If the mass of a body is halved and its velocity doubled, its momentum will not change. Explain.

If the number of molecules of a gas in a container is doubled what will be the affect on pressure and rms speed?

By doubling the mass of a solid body, its density becomes-

The efficiency of a Carnot engine is frac(1)(6) when temperature if the sink decrease by 65 K its efficiency becomes frac(1)(3) . Calculate the initial and final temperature.

An object of mass 100 kg is accelerated uniformly from a velocity of 5 m s^-1 to 8m s^-1 in 6 s. Calculate the initial and final momentum of the object. Also, find the magnitude of the force exerted on the object.

The rate of a gaseous reaction becomes half when volume of the vessel is doubled. What is the order of the reaction?

In the reaction A + B rarr Product , the initial rate becomes 4 times if the concentration of A is doubled (keeping B constant) and rate becomes doubled when we double the concentration of B (keeping A constant), what is the rate law and order of the reaction?

What will be the potential energy of a body when its mass becomes doubled.

From a rifle mass 4kg a bullet of mass 50g is fired with an initia, velocity of 35 ms^-1 . Calculate the initial recoil velocity of the rifle.

A bullet of mass 40gm is fired from a gun of mass 8kg with a velocity of 800 m/s, calculate the recoil velocity of gun.
