I know there is an ether but there is also something else. What is it? I have tried to find a group that is in the compound, but I have had no luck. It seems to be...
light is refracted when it enters another medium. this is based on the index of refraction of the medium the light enters. Denser mediums have higher indexes, which leads to lower speeds of light. Although acceleration or deceleration usually apply to matter, in this case it would make sense to...

A uniform crate with a mass of 14.1 kg rests on a floor with a coefficient of static friction equal to 0.551. The crate is a uniform cube with sides 1.21 m in length.
If a horizontal force is applied to the top of the crate, what is the magnitude of the horizontal force...
at the top of the path, the normal force the bucket exerts on the water is 0. therefore, applied force, which is equal to normal force, is 0. Thus mg=(m)(v2/r) solving for v gets 5.94 m/s.
