Thee acceleration due to gravity on Earth is maximum at, Equator, Poles, Center of Earth , Everywhere same, kepler's first law states that planets move in, Circles, Straight line , Parabolas, Ellipses, Which law explains equal area in equal Times, Newton's first law , Kepler's first law , Kepler's second law, Kepler's third law , Centre of mass depends on, Shape only , Mass distribution , Volume only , Density only , The centre of mass of a system can lie, only inside the body, only outside the body, either inside or outside, only on the surface, At the mean position of SHM , velocity is, Zero, Minimum, Maximum, Constant, When force and displacement are in opposite directions , work done is, Zero, None, Positive, Negative, A force of 10 N moves an object by 5 m in the same direction. Work done is, 2 J, 15 J, 50 J, 100 J, The first law of thermodynamics is based on, Conservation of mass, Conservation of energy , Conservation of Moment , Conservation of charge , In an isothermal process, which quantity remains constant , Pressure, Volume, Temperature, Internal energy .
