The second law of thermodynamics states that the state of entropy of the entire universe, as an isolated system, will always increase over time. The second law also states that the changes in the entropy in the universe can never be negative.
There's no possible way to think about the validity of that equation until we know what the variables v, R, and g represent.
Answer:
v = 6295.55 m/s
Explanation:
Given that,
The radius of a planet, 
The free fall acceleration of the planet, a = 7.45 m/s²
We need to find the tangential speed of a person standing at the equator.
Also, the centripetal acceleration was equal to the gravitational acceleration at the equator.
We know that,
Centri[etal acceleration,
So, the tangential speed of the person is equal to 6295.55 m/s.
When the temperature increases the volume will increase, and when it cools it will decrease. This is because the molecules spread further apart as the temp gets higher, which creates a bigger volume.
The chair and floor have a static friction coefficient of 7.9523 and a kinetic friction coefficient of 0.8114, respectively.
<h3>What causes static friction?</h3>
The braking force of an item is static friction. The resistance humans encounter when attempting to move something fastened to the ground without actually moving thier own bodies or the surface that are sitting on is described as static friction.
<h3>What causes static friction to form?</h3>
Adhesion, a slight chemical attraction between contact objects, is what causes static friction. Friction is also produced by the interaction of the flaws on each surface.
