Class X Formula for gravitational potential energy is Ep = mg/h, where m is mass, g is gravitational pull and is height Ep = m/gh, where m is mass, g is gravitational pull and is height Ep = mgh, where m is mass, g is gravitational pull and is height Ep = gh/m, where m is mass, g is gravitational pull and is height Mass of a car is 500 kg, which is lifted up by a crane at a height of 200 m, gravity is 10 N kg-1. Ep of car will be 1000000 J 10000 J 4 J 25 J A bus travelling eastwards at 60 m s-1 takes 10s to come to halt, its deceleration is equal to 6 m s-1 eastward -6 m s-1 eastward 6 m s-1² eastward -6 m s-1² eastward In physics, pressure is defined as P = A × F P = A/F P = F/A P = F/d Volume of mercury is 0.4 m³ and mass is 5440 kg, density of mercury is 1360 kg m-3 136 kg m-3 13600 kg m-3 13.6 kg m-3 Do you really want to submit this quiz?
