Hi,
The Capture Theory pro<span>poses that the moon was a passing asteroid pulled into orbit by earth's gravity.
The Capture Theory is not a valid theory, per se. The Impact Theory is the theory most recognized. The theory states </span><span>that the moon formed from dust produced by a collision between Earth and another large body.

Explanation:
if radius is greater than the force acting on that object is more and if the radius is smaller then the force acting on it is less.
Answer:
6.4 m/s
Explanation:
From the question, we are given that
Speed of the river, v(r) = 5 m/s
velocity relative to the water, v(w) = 4 m/s
Width of the river, d = 780 m
The magnitude of his velocity relative to the earth is v(m)
v(m) can be gotten by using the relation
[v(m)]² = [v(w)]² + [v(r)]²
[v(m)]² = 4² + 5²
[v(m)]² = 16 + 25
[v(m)]² = 41
v(m) = √41
v(m) = 6.4 m/s
thus, the magnitude of the velocity relative to earth is 6.4 m/s
To calculate the velocity relative to car A, you have to add the opposite of the velocity of car A to car B.
the velocity of car B relative to car A:
(let east and north directions be positive)
v = v (car B) - v(car A)
v(east-west direction) = -120 * cos 30° - 110
v(north - south direction) = -120 * sin 30° - 0
