B is correct. Every object has gravity, the more mass the object has, the stronger the gravitational pull, so the ship being closer to the moon makes the weight increase.
Not that we know of today, but we didn't know about dark matter until a few years ago.
Volume = mass / density
Volume = 20 / 7.87
Volume = 2.54 (2 s.f)
Answer: Mathematical Model
Explanation:
Took the test
Newton's third law: If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A. This law represents a certain symmetry in nature: forces always occur in pairs, and one body cannot exert a force on another without experiencing a force itself.
