When the roller coaster moves down from the top of the hill, all of its stored potential energy is converted into kinetic energy to move it and when it goes back up the hill it turns kinetic into potential.
Answer:
60 V
Explanation:
Let the potential on capacitor be V . This will be equal to voltage of the source .
During discharge this voltage of capacitor will create current .
V / 120 = .5
V = 60 V
So this would have been the voltage of the source . So voltage of source
= 60 V
Answer:
C
Explanation:
The total kinetic energy is the sum of the kinetic energy in the center of mass (Rotational Kinetic energy) plus the kinetic energy of the center of mass( Translational Kinetic Energy).
The formula
is applicable only when
The moment of inertia must be taken about an axis through the center of mass.
<u>Answer </u>
kinetic
<u>Explanation</u>
Matter is anything that occupies space and has mass. There are four states of matter, solids, liquids, gases and plasma. All this consist of small molecules that are in constant random motion. This is called kinetic theory of matter.
When these molecules are in motion they may collide. No energy is gained or lost during collision. The particle/molecules move in a constant linear motion.
