If two balls of same metal weighing 5 gm and 10 gm strike with a target with the same velocity. The heat energy so developed is used for raising their temperature alone, then the temperature will be higher

two copper balls having masses 5 gm and 10 gm collide with a target with the same velocity. If the total energy is used in heating the balls. Which ball will attain higher temperature?

Two metal balls having masses 50g and 100g collides with a target with same velocity. Then the ratio of their rise in temperatures is

Two metal balls having masses 50g and 100g collides with a target with same velocity. Then the ratio of their rise in temperature is

A lead bullet (Specific heat= 0.032" cal/gm"^(@)C ) is completely stopped when it strikes a target with a velocity of 300 m/s . The heat generated is equally shared by the bullet and the target. The rise in temperature of bullet will be

A lead bullet (specific heat=0.032cal/gm .^(@)C ) is completely stopped when it strikes a target with a velocity of 300m/s. the heat generated is equally shared by the bullet and the target. The rise in temperature of bullet will be

A bullet of mass 10 gm strikes a target at 400 m//s velocity and does half of its initial velocity. The loss of kinetic energy in joules is

One mole of an ideal gas requires 207 J of heat to raise the temperature. If the same gas is heated at constant volume to raise the temperature by the same range, the heat required will be [R=8.3 J/mole K]

Two ball at the same temperature collide which is consved?
