A generator transforms mechanical into electrical, a transformer reduces/increases the voltage of an alternating current, a magnet attracts metal, and a motor converts electrical energy into mechanical energy.
So, the answer is Motor.
When you do work to lift the object, the amount of work you do BECOMES the object's gravitational potential energy. It GETS its potential energy from the work you do to lift it. They're equal. You lose it, and the object gains it. Energy is not created or destroyed. It's just transferred from you to the object.
Later, when you DROP the object, GRAVITY does the same amount of work on it, to pull it to the ground. Again, no energy is created or destroyed. Every time a force acts to move anything, the energy to do it comes from somewhere, and the energy goes somewhere.
Answer:
quasars are massive celestrial bodies that are far or remotely placed emitting large energy radiations.
parallax is the best way of determining distances between astronomical bodies and parallaxes of stars are measured relative to a quasar to minimise the measurement error. each observations is stimulated with the basic angle variations leading to minimum uncertainty in the results as the assumptions in the measurements are as minimal as possible.
Answer:
155 118 in
Explanation:
3.94 km * 1000 m / km * 39.37 in / m = 155 118 in
The intensity of light is related to our perception of brightness.
