A hollow sphere with a mass of 2 kg and a radius of 15 cm rolls without slipping down a 30° ramp. Starting from rest, how long does it take (in s) for it to travel 14.7 m down the ramp? You may assume that no energy is dissipated due to friction.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
