According to the Law of Universal Gravitation, the gravitational force is directly proportional to the mass, and inversely proportional to the distance. In this problem, let's assume the celestial bodies to be restricted to the planets and the Sun. Since the distance is specified, the other factor would be the mass. Among all the celestial bodies, the Sun is the most massive. So, the Sun would cause the strongest gravitational pull to the satellite.

Speed is a scalar quantity that refers to “how fast an object is moving.”

**Answer:**

1 and 4, 2 and 3, 5 and 9, 6 and 8

**Explanation:**

7 would not have a pair because there is not enough statements

**Answer:**

5.66 m/s

**Explanation:**

p=mv

255 = 45v

v = 255/45

v = 5.66 m/s

If you want to verify your answer, just insert your value to the equation.

**Answer:**

Magnetic Forces on Moving Charges. The magnetic force on a free moving charge is perpendicular to both the velocity of the charge and the magnetic field with direction given by the right hand rule.
