What is the name of the force that slows it down?.

A beam of light from a monochromatic laser shines into a piece of glass. The glass has thickness L and index of refraction n=1.5.

a ball was projected in such a way that it attained the maximum horizontal distance with a velocity of 20m/s calculate the vertical distance reached

The kinetic or potential energy associated with the motion and position of an object is a. nuclear energy. b. thermal energy. c. gravitational potential energy. d. mechanical energy.

Determine the total mechanical energy of a 250 g baseball if it has a velocity of 30 m/s when it leaves the pitcher's hand 1.2m above the ground.

When distances were carefully measured from Earth to globular clusters above and below the Milky Way plane (where our view of them is not obscured by interstellar dust and gas), their distribution was found to be

Imagine you transfer heat into a gas. This heat splits up in two different ways: Additional thermal energy making the gas hotter and "fuel" for the gas to do work. Let's suppose, 64% of the transferred heat transforms into thermal energy.

How much heat is absorbed by a 61g iron skillet when its temperature rises from 5oC to 29oC?

Explain the relationship between motion and frame of reference.
