    Some light properties

    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...

    Torque problem with a crate

    Homework Statement 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...

    Circular motion of a bucket

    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.

    Circular motion of a bucket

    the normal force and gravity must equal the applied force. But if that is the case, then ay is 0 and the problem is unsolvable.
