Answer:
a and b
Explanation:
Hydro static equilibrium holds a star steady and balanced. Whenever a star stops burning hydrogen in its center, there must be evolutionary improvements to maintain equilibrium for the star Of example, if a star's internal pressure and temperature fall, gravity will take over and force the star to contract and heat up, restoring stability. By contrast, if a star's internal pressure and temperature rises, the extra pressure causes the star to widen and cool, restoring balance.
so, according to above explanation options a and b both are true
a) A small increase in the star's internal pressure and temperature causes the star's outer layers to expand and cool.
b) A small decrease in the star's internal pressure and temperature causes the star's outer layers to contract and heat up.
Geology because It is the study of processes that shape Earth.
Answer:
the answer is the diagram B
The displacement would be the final position (37) minus the initial position (50) if using the displacement formula.
In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force
