Answer:
8 meters per second per second
Explanation:
Newton's second law: 
, force = mass multiplied by acceleration.
Therefore 56 / 7 = acceleration = 8

Answer: Option D
Quantity A is mass and Quantity B is weight.
Explanation:
Mass of the body is the amount of matter in that body. The amount of matter remains the same regardless of the position or location of the body. Mass is also not affected by gravitational pull. Thus mass remains constant everywhere. Mass of the body will be the same on Earth and on Moon.
Hence Quantity A represents mass
Weight of the body is totally dependent on the gravitational pull. Infact, weight is calculated as mass times gravitational acceleration (g) i.e.
w = mg
Weight will vary at different positions. Weight of a body on Earth will be different than its weight on moon because the gravitational pull of Earth and Moon is different.
Hence Quantity B represents weight.
