A lead bullet weighing 20 g and moving with a velocity of `100 ms^(-1)` comes to rest in a fixed block of wood. Calculate the heat developed and the rise in temperature of the bullet assuming that the half of the heat is absorbed by the bulley. The specific heat of lead is `0.03 cal g^(-1).^(@)C^(-1)`.

A bullet moving with a velocity of 230 m/s is stopped by a block of wood. Calculate the rise in temperature of the bullet assuming that all the heat generated is retained by the bullet. Specific heat capacity of lead = 126 J/kg/K.

A lead bullet strikes a target with a velocity of 500 ms^(-1) and the bullet falls dead. Calculate the rise in temperature of the bullet assuming that 40% of the heat produced is used in heating the bullet. Given specific heat of lead = 0.03 cal g^(-1).^(@)C^(-1), J = 4.2 J cal^(-1) .

A bullet of mass 20xx10^(-3)kg enters into a fixed block of wood with a velocity of 100ms^(-1) and is brought to rest in the wood. Calclate the rise in temperature of te bullet if two -third of the heat produced is absorbed by the bullet. (Specific heat capacity of lead =32calkg^(-1)K^-1) and J=4.2J//"callorie" )

Mass of a piece of cppper is 20 g. Find the rise in temperature of the piece when 100 cal of heat is supplied to it? Specific heat of copper ="0.09 cal. g"^(-1).^(@)C^(-1).

A lead bullet of mass 21g travelling at a speed of 100 ms^(-1) comes to rest in a wooden block. If no heat is taken away by the wood, the rise in temperature of the bullet in the wood nearly is (Sp. Heat of lead 80cal/kg .^(@)C )

If a lead bullet hits a wall, its temperature rises by 200^(@)C . What is the speed of the bullet if the heat so produced remains completely in the bullet? Specific heat of lead = 0.03 cal cdot g^(-1) cdot^(@)C^(-1) .

A lead bullet of mass 21 g travelling at a speed of 100m//s comes to rest in a wooden block . If no heat is taken away by the wood , the rise in temperature of the bullet in the wood nearly is (specified heat of lead = 30 cal//kg^(@)C )
