Im pretty sure the answer would be thermometer
The four classes of polymers are:
1. Nucleic acids. Examples are DNA and RNA
2. Protein. Examples are enzymes and hemoglobin
3. Carbohydrates. Examples as starch and glycogen
4. Lipids. Examples are triglycerides and phospholipids
The building blocks of nucleic acids are called bases and there are four types known as Guanine, Adenine, Thymine and Cytosine.
The building blocks of carbohydrates are glucose molecules.
The building blocks of protein are amino acids.
The building blocks of lipids are a combination of fatty acids and glycerol.
The resultant of the given forces is; 6√2 N
<h3>How to find the resultant of forces</h3>
We are given the forces as;
10 N along the x-axis which is +10 N in the x-direction
6 N along the y-axis which is +6N in the y-direction
4 N along the negative x-axis which is -4N
Thus;
Resultant force in the x-direction is; 10 - 4 = 6N
Resultant force in the y-direction is; 6N
Thus;
Total resultant force = √(6² + 6²)
Total resultant force = 6√2 N

<u>Answer:</u>
The correct answer option is D. The distance between the planet and the Sun changes as the planet orbits the sun.
<u>Explanation:</u>
Kepler’s laws of planetary motion, derived by the German astronomer Johannes Kepler, are the laws of physics that describe the motions of the planets in the solar system.
According to the Kepler's first law of planetary motion: the path on which the planets orbit around the sun is elliptical in shape, with the center of the sun at one focus.
Therefore, the distance between the Sun and the planets vary as the planet orbit around the sun.
First, we need to find the number of protons, which is the total mass divided by the mass of one proton:

protons
Then, the total charge is the number of protons times the charge of a single proton:
