On the moon, what would be the force of gravity acting on an object that has a mass of 7kg?
1 answer:
Answer:
Force of gravity, F = 70 N
Explanation:
It is required to find the force of gravity acting on an object that has a mass of 7 kg. Force of gravity always acts in downward direction.
The force of gravity is equal to the weight of an object. It is given by :
g = acceleration due to gravity, for Earth, g = 10 m/s²
So,
So, 70 N of force of acting on an object.

b. a large elliptical galaxy
Explanation:
In elliptical galaxies the stars are grouped in an elliptical shape, it has a low quantity of gas and dust in comparison to spiral galaxies, and its stars belong to an old population, there is not new stellar formation in it.
The stars orbit in a messy way which made to believe that they form from the merger of galaxies.
They are also really massive (around solar masses).
The most massive and luminous can be found in the center of cluster of galaxies.
