Question 2 (1 point) Which of the following are correct descriptions of a force? 1 A force is a push or pull on an object. 11 A force has a magnitude, a unit, and a direction. III The SI unit of force is the newton (N). IV A force acting on an object can change its mass.
( 12.000- 1.50x10m The gravitational force exerted on Earth by the Moon is 1.9 X 1020 N (toward the Moon's centre). The gravitational force exerted on Earth by the Sun is 3.5 X 1022 N [toward the Sun's centre). The magnitude of the net gravitational force exerted on Earth by the Moon and the Sun is a.bX 100 N.
