Atoms gain energy as a solid changes to a liquid. If atoms energy during a change of state, they are pulled together by attractive forces and become more organized.
<u>Given data:</u>
M.A. = 8 (No units),
Ramp height (h)= 1.5 m, lifted,
Determine how long is the ramp=?
<em>General formula </em>
<em> Mechanical Advantage = (Ramp length) ÷ (Ramp height),</em>
<em> M.A = l ÷ h </em>
<em> 8 × 1.5 = l = 12 m long</em>
<em>length of the ramp l ramp = 12 m</em>
This is an example Newton's Third Law. All the kinectic energy from the moving car transferred the potential energy of the parked car. This potential is not much since the brakes are on (hopefully) and it's not in a non-moving position.
The answer to the question is true
Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.
