A body of mass 42 kg is dragged on a horizontal rough road (coefficient of friction = 0.6) with a constant speed of 18 kmph. If 50% of the heat generated in 1.5 hour is absorbed by the body then is the rise in temperature (in degree celsius). (Note: Take specific heat of the material of the body to be 0.1 cal g = 10ms? `

A sample gas undergoes adiabatic process which is compressed from 900 cm to 450 cm. How much work is done by the gas if initial pressure is 150 122 Take Y as 1.3.
