Energy is never created and energy never is destroyed
krok68 [10]3 years ago

Explanation:

The process in which energy gets transferred from one form of energy to another is called energy transformations. This process also defines the law of conservation of energy.          

"Energy is neither be created nor be destroyed" is explained by the law of conservation of energy. It only changes one form of energy to another.

There are many forms of energy i.e. electrical energy, mechanical energy, electromagnetic energy, sound energy etc.

The example of energy transformation is best explained by a roller coaster. At the top of a big hill, there exists only kinetic energy. As it descent the hill, the kinetic energy is converted to gravitational potential energy.

Hence, the correct options are (c) Energy is never created. and (e) Energy is never destroyed.

What is a partial and total lunar eclipse?
Minchanka [31]

Partial Lunar Eclipse:

A partial lunar eclipse is when the earth gets between the Sun and Moon. However, all three bodies are not in alignment meaning we are able to see some more like part of the moon's surface as it moves in route of the Earth's shadow.

Total Lunar Eclipse:

The three celestial bodies are perfectly aligned which allows for the earth to completely block the sun's rays from hitting/reaching the moon. The sun is positions is in back of the Earth which then causes the shadow of the earth to be cast on the Moon covering the moon completely. When that happens you get the phenomenon called a total lunar eclipse.

Hopefully this helped and good luck.

Answer:

<u>Question 2</u>

<u>Part (a)</u>

Chlorine:  type of compound = chloride

Oxygen:  type of compound = oxide

<u>Part (b)</u>

The iron reacts with water and oxygen to form rust.

A water molecule is made up of two hydrogen atoms joined to one oxygen atom:  Di-hydrogen oxide.

<u>Question 3</u>

This circuit is in parallel.

The current in a parallel circuit splits into different branches then combines again before it goes back into the supply.

We are told that A₁ = 0.8 A

As the lamps have <u>equal resistance</u>, the current splits equally:

A₂ = 0.4 A

A₃ = 0.4 A

Then combines again:

A₄ = 0.8 A
