12 we throw a ball upwards it will come to the ground by a force called
a.Friction
B. gravity
C. magnetic D. Velocity
13. Earth orbits around the sun because there is
a.gravitational push from the Sun on the Earth
B. gravitational pull from the Sun on the Earth
C.The Earth is pulled towards the sun rather than going off in a straight line
D strong magmetic interaction between the Sun on the Earth. The Gravitional Interaction between the sun and the earth is small.

Answer:
12)B.
13)B.
Explanation:
12)Once you release the ball, you are not applying a force to it; it is freely falling (despite its upward motion). The only force acting on it is the gravitational force, pulling it downwards (which is why it slows down and stops momentarily at the apex, before coming back down).
13)Anyway, the basic reason why the planets revolve around, or orbit, the Sun, is that the gravity of the Sun keeps them in their orbits. Just as the Moon orbits the Earth because of the pull of Earth's gravity, the Earth orbits the Sun because of the pull of the Sun's gravity.
