Answer

Brief Explanations:

For the first question, according to Newton's law of universal gravitation, the gravitational pull between two objects depends on their masses. For the second question, in the absence of air - resistance, an object in free - fall near the Earth's surface has a constant acceleration of approximately 10 m/s². Starting from 0 m/s, after 1 s it is at 10 m/s, and after 2 s, using the formula (v = v_0+at) (where (v_0 = 0), (a = 10m/s²), and (t = 2s)), it will accelerate to (v=0 + 10\times2=20m/s).

Answer:

  1. B. mass
  2. C. the ball will accelerate to 20 m/s
