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.
Answer:
They have mass is always true.
<span>all life on Earth is
sustained by energy from sunlight. This energy is transmitted from sun
to Earth in the form of electromagnetic radiation emitted by hot gas at
the sun's surface. The sun is heated by nuclear fusion taking place
within its core.</span>
Answer:
PE = 882 J
Explanation:
Through the International System we know that the gravity of the earth is 9.8 m/s², so...
Data:
- m = 45 kg
- g = 9.8 m/s²
- h = 2 m
- PE = ?
Formula:
Replace and solve:
The potential energy of the sled is <u>882 Joules</u>.

When a star collapses to form a black hole,
its mass increases, that is letter C. One example of this is the Big Bang
Theory.
<span>
It is by no doubt that our universe had had its own
starting point but how it really started became a debate for the scientists
over the past centuries. From theories such as Ekpyrotic theory, White Holes,
Matrix theory, and Quantum theory, the Big Bang theory is the theory mostly
accepted by scientists. According to the theory, the universe started as a
singularity, that is, from a black hole under extreme gravitational pressure
and expanded (instead of exploded) and cooled. Its cooling, according to the
theory, is still happening now as of the moment.</span>
