Answer:
The correct option is;
E. motion of tectonic plates.
Explanation:
The Moon is formed from the Earth, and so have similar composition. However, the smaller size of the moon as well as the low temperature of the Moon's mantle compared to the interior of the earth, contribute the state of the Moon having no active tectonic plate motion and no convection.
The convection in the mantle, drives Earth's tectonic plate motions. The mantle within Earth moves at a rate of some centimeters annually, while the Moon, geologically is a dying world.
I’m pretty sure it’s a starting point... unless it’s asking for an actual object
A pull between two objects, for example, between an object and Earth. When forces on an object are balanced, there is no change in speed or direction.
So the answer is I agree
Answer:
The experiment to determine the coefficient of static friction between a rough block and an incline plane is detailed in the explanation.
Explanation:
A simple experiment is as follows:
Take a weight in which its mass is known and hold it with a roller at the end of the inclined plane with a rope.
Place the weight on the plane inclined horizontally with the ground, forming a zero degree angle.
Gradually lift the weight so that the angle of incline begins to increase.
Observe that the weight will begin to slide. This angle will be the angle theta.
In this way, the coefficient of friction will be calculated as the tangent of the angle theta.
Take a different weight and repeat the procedure to get different values of the coefficient of friction.
By averaging the coefficients of friction, a final value will be obtained.
