Answer:
Mass of the silver will be equal to 46.70 gram
Explanation:
We have given heat required to raise the temperature of silver by 24°C is 269 J , so 
Specific heat of silver = 0.240 J/gram°C
We have to find the mass of silver
We know that heat required is given by
, here m is mass, c is specific heat of silver and 
is rise in temperature
So 
m = 46.70 gram
So mass of the silver will be equal to 46.70 gram
Explanation:
As it is given that hot pan of copper is dropped into a tub of hot water and the temperature of water rises. This means that heat from the pan has been released and this heat is gained by water.
As a result, temperature of copper pan has decreased and this decrease will continue till the time temperature of both copper pan and water will reach the same temperature.
As thermal energy is defined as the energy in which when two objects come in physical contact with each other then no exchange of heat energy will take place.
Thus, we can conclude that when temperature of both copper pan and water will be equal then it means that both of them has reached thermal equilibrium.
Greater the mass greater is inertia. Greater the inertia greater is the force required to stop motion of an object. Linear motion depends only on mass whereas rotational motion depends on mass, size and shape of an object. So conclusion is that it would be difficult to stop 10 kg mass cuz of greater inertia compared to 1kg mass. Hope it clears your doubt.
It depends on how you want to solve it you can solve it in many different meathods:$
