Answer:
revolution of the planets around the Sun.
Explanation:
The revolution of the planets around the Sun is a result of the gravitational force exerted by the Sun. The Sun's gravitational pull attracts the planets, causing them to move in an elliptical orbit around it. This motion is known as the revolution of the planets around the Sun. The other options listed (rotation of the planets on their axes, rotation of the Moon on its axis, and revolution of the Moon around Earth) are also related to motion and gravity, but they are different phenomena.
Answer:
b) 67.5 N
Explanation:
Force (F) = mass (m) × acceleration (a)
The mass (m) is 45 kg, and the acceleration (a) is 1.5 m/s². Plug these values into the formula:
F = 45 kg × 1.5 m/s²
F = 67.5 N
So, the force created by the person is 67.5 Newtons.
The right answer is 280 N.
When a woman stands with two feet on a scale, the scale reads 280 N and when she lifts one foot, the scale also reads 280 N because the weight of the other leg also comes on the one leg.
First, the whole weight of the body depends on two feet but when the second feet is lifted, the weight of the whole body including the lifted feet comes on the single feed so we can conclude that the right answer is 280 N

Answer:
402m
Explanation:
We can solve this easily by using the free fall formula:
On both cases the final velocity will be 0m/s (maximum height), so we have:
We know that the velocity the person imparts to the ball will be the same either on Earth or on the Moon, so we write for both cases:
Which means
So we get (taking into account that gravity on earth is 6 times gravity on the Moon):
