A type of matter made up of a combination of elements is called a compound. for example table salt, is made up of two elements that by themselves are lethal but chemically combined cancel each other out there for becoming edible.

What is storage of energy

Talja [164]

Hey,

Storage of energy is known as potential energy. If you take a spring for example, and you stretch it then you hold it, it has the energy you put into it but it is potential since it's not moving. Of course once you let go of it its potential energy turns into kinetic energy.

There are other examples as well, such as a battery. I decided to use the spring example because it is simpler.

I hope it helped.

I wrote all that^.

1. A plane flying a triangular patter flies 150 km[N], then 400 km(E). What is the total displacement of the

zhenek [66]

Answer:

1. The displacement is 427.2 km.

Explanation:

1. A = 150 km North

B = 400 km East

The net displacement is given by

$R =\sqrt{400^2 + 150^2 }\\\\R = 427.2 km$

Times will the kinetic one

mixer [17]

Answer:

The new kinetic energy is 9 times of the initial kinetic energy.

Explanation:

The kinetic energy of an object is given by the formula as follows :

$E=\dfrac{1}{2}mv^2$

Where

m is mass and v is speed of the body

If the speed of the body is tripled. Let v' is the new speed, v' = 3v. The new kinetic energy is E' and it is given by :

$E'=\dfrac{1}{2}mv'^2\\\\\text{Put v' = 3v}\\\\E'=\dfrac{1}{2}m\times (3v)^2\\\\=\dfrac{1}{2}m\times 9v^2\\\\=9\times (\dfrac{1}{2}mv^2)\\\\E'=9\times E$

Hence, the new kinetic energy is 9 times of the initial kinetic energy.
