Answer:
Force of gravity
Explanation:
when the force of gravity pulls large gas clouds and dust together, the concentrated gas clouds and dust collapse under the force of gravity forming stars.
There are many galaxies out there in the universe, each galaxy has its own solar systems, stars, and collection of gas and dust. We (earth) belong to the Milky Way galaxy, our galaxy got this name from the Romans. They called in 'via lactea', which directly translates to 'road of milk' because of the milky patch they saw at night.
The answer to this would be C
<u>Answer</u>
9 m
<u>Explanation</u>
The energy stored in a spring is given by:
Energy = 1/2 k²e
Where e is the compression and k is the spring constant.
Energy = 1/2 × 176,400 × 0.2²
= 3,528 N
The same energy will then be converted to potential energy given by:
Energy = mgh
Where m is the mass, g is the gravity and h is the height above the ground.
Energy = mgh
3,528 = 40 × 9.8 × h
3,528 = 392h
h = 9 m
