Answer:
The atmosphere is a thin layer of gases that surrounds the Earth. It seals the planet and protects us from the vacuum of space. It protects us from electromagnetic radiation given off by the Sun and small objects flying through space such as meteoroids.
The region of the spectrum that best corresponds to light with a wavelength equal to;
1) The diameter of a hydrogen atom is; X-ray
2) The width of your pinky finger; microwaves.
3) The size of a virus; X-ray and Ultraviolet rays.
<h3>Electromagnetic spectrum</h3>
- From online tables, the diameter of an hydrogen atom is approximately 1 × 10^(-10) m but according to electromagnetic spectrum, any wavelength between 10^(-8) m and 10^(-12) m is an x-ray.
- From online tables, width of your pinky finger is 1.06 × 10^(-2) m but according to the electromagnetic spectrum the range between 1 and 10^(-3) m corresponds to microwave.
- The size of a virus has the range from 2 × 10^(-9) m to 4 × 10^(-7) m. This Range falls into x-ray or ultraviolet rays.
The complete question is;
What region of the spectrum best corresponds to light with a wavelength equal to:
(1) the diameter of a hydrogen atom
(2) the width of your pinky finger
(3) the size of a virus
Choices:
(A) radio
(B) mircowave
(C) infrared
(D) visible light
(E) gamma ray
(F) x-ray
(G) ultraviolet

The coordinates of p without using any new variables are; (a, b).
<h3>Finding Rectangle Coordinates</h3>
From the properties of a rectangle, we know that;
- each of its angle is a right angle.
- each side of the rectangle is perpendicular to its adjacent side.
- the distance of a point from a line is the length of the perpendicular drawn from the point to the line.
From the rectangle image attached, we can see that;
Point P is at a distance of b units from x-axis and a units from y-axis.
Thus, the coordinates of Point P is (a, b)
