Answer:

1. Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in the Solar System. Clyde Tombaugh carefully studied images of the night sky, and after a lot of hard work he finally discovered Pluto.

2. Well, Pluto was most likely difficult to find, because of its small size and great distance from Earth.

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^.
