Answer:
1) Kepler's three laws of planetary motion can be stated as follows: (1. All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. (2.A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time. The image is also attached below....
2) The weight of the man would be 90 kg on the Earth. Then it will be 90/6 = 15 kg on the Moon.
3) If a carpet is beaten with a stick then the carpet begins to move. But, the particles of dust are trying to resist their state of rest. The dust particles remain in a state of rest, while the carpet moves, as per Newton's first law of motion. The particles of dust thus emerge from the carpet.
4) I don't know.... Sorry for that.
5) The inverse square law proposed by Newton suggests that the force of gravity acting between any two objects is inversely proportional to the square of the separation distance between the object's centers. Altering the separation distance (d) results in an alteration in the force of gravity acting between the objects.
