36) Ravi is attending an interview at Kochi which is 400 km from his home. He plans to leave home at 7.00 AM and drive at 100 km/hr so that he reaches for the interview scheduled at 11.00 AM on time. Ravi drives at that speed of 100 km/hr for the first 200 km,

37) A stone is dropped into a river from a stationary balloon 405 m above water. Another stone is thrown vertically down 1.00 s after the first is dropped. The stones strike the water at the same time. The initial speed of the second stone is (acceleration due

38) The head loss due to friction in a pipe of 1 m diameter and 1.5 km long when water is flowing with a velocity of 1 m/s is (Darcy's friction factor fd = 0.02 and acceleration due to gravity g=10 m/square second)

39) A stationary mass of gas is compressed without friction from an initial state of 0.3 cubic meter and 0.105 Mpa to a final state of 0.15 cubic meter and 0.105 Mpa, the pressure remaining constant during the process. There is a transfer of 37.6 kJ of heat fr
