A pie chart uses wedges to show the amount of data points in a category.
Answer:
Electromagnetic radiation is made when an atom absorbs energy. The absorbed energy causes one or more electrons to change their locale within the atom. When the electron returns to its original position, an electromagnetic wave is produced. ... These electrons in these atoms are then in a high energy state.
Explanation:
Answer:
We have many uses for infrared: night-vision cameras, remote controls, infrared astronomy, and fiber-optic cables. The greenhouse effect is even related to infrared waves because greenhouse gases absorb the infrared emitted by the ground, trapping it on the Earth.
Explanation:
The sun, that's our main source. Without it the world can die
Answer:
The angle is 
Explanation:
From the question we are told that
The objective focal length 
The eyepiece focal length is 
The diameter of the sunlight is 
The distance of the sun from from the earth is
Generally the magnification of the object is mathematically evaluated as

The negative sign is because the lens of the telescope is diverging light
substituting values


Now we can obtain the angle made by the object (sunlight ) with respect to the telescope as follows

substituting values


![\theta= tan^{-1}[0.0001667]](https://tex.z-dn.net/?f=%5Ctheta%3D%20%20tan%5E%7B-1%7D%5B0.0001667%5D)

The magnification can also be mathematically represented as

Where
is the angle the image made with telescope
Since the negative sign indicate direction of light movement we will remove it from the calculation below
