Determine the time it takes for a satellite to orbit the moon in a circular "near-moon" orbit. a "near-moon" orbit is at a height above the surface of the moon that is very small compared to the radius of the moon. [hint: you may take the acceleration due to gravity as essentially the same as that on the surface.]

Two polarizers are oriented at 70∘∘ to one another. unpolarized light falls on them. what fraction of the light intensity is transmitted?

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

The material that keeps its new shape after it is stretched is called?
