A Changing the mass of an object B Changing the velocity of an object C Changing the shape of an object D Changing the direction of motion of an object

Diagram 2 shows a boy using the correct long jump technique to avoid injury to his legs. What is the reason for the above situation?

A Increase the force B Increase the impulse C Reduce the momentum D Reduce the impulsive force

Newton's Universal Law of Gravitation states that

A The gravitational force between two bodies is directly proportional to the product of the masses of both bodies and inversely proportional to the square of the distance between the centers of the two bodies B A line that connects a planet to the Sun sweeps out equal areas in equal times C All planets move in elliptical orbits with the Sun at one focus D The square of the orbital period of any planet is directly proportional to the cube of the radius of its orbit

A Temperature of L is higher than M B The quantity of heat in L is the same as in M C Rate of change in temperature of L is bigger than that of M D Net heat transfer between L and M is zero

Why does a person feel cold after swimming in the sea if the body is not dried immediately?
