Answer:How is potential energy converted to thermal energy in a system?
Explanation:
Relative motion is the calculation of the motion of an object with regard to some other moving object.
<span>P= work/time and work is = to force x distance so its 500x4 =2000joules
and 2000/4 =500 watts</span>
Answer:
The oldest stars in spiral galaxies are younger than the oldest stars in elliptical galaxies.
Explanation:
Spiral galaxies have a greater star formation than elliptical galaxies, since the latter contain less gas and dust. Therefore, the rate of creation of new stars is lower in elliptical galaxies. These galaxies are dominated by old stars, with a long evolution. While the spiral galaxies have stars with a faster evolution.
The correct answer is:
= g
Explanation:
When the object leaves the hand it has a force acted on it mainly it’s weight.
