Question

How would the absence of gravity affect the formation of planets?

A The rocks and debris would take longer to accrete into a planet.

B The rocks and debris would never accrete into a planet.

C The rocks and debris would accrete into a smaller orbiting body.

D The rocks and debris would be pushed closer to the Sun.

Answer 1

The correct answer is B. The rocks and debris would never accrete into a planet.

Step-by-step explanation:

Gravity refers to a force of attraction between objects due to their masses. This force is described through the formula F= G M m/ r2 in which G is equal to the gravitational constant, M and m describe the mass of objects, and r refers to the distance.

Moreover, gravity was essential for the formation of planets, stars and other elements in the universe, because this caused gas, dust, rocks, and other particles or elements to aggregate or accrete into planets and other celestial bodies. Moreover, gravity is responsible for phenomena such as planets orbiting. The previous idea implies that without gravity the formation of planets would not have possible and therefore "the rocks and debris would never accrete into a planet".

Answer 2

Answer : The rocks and debris would never accrete into a planet.

Explanation : Gravity is an attraction force and dependents on the mass of the objects but in the absence of the force the rocks and debris would not come together to form a clump.

So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet.
