Answer:
The average atomic mass of X is 206.0346
Explanation:
Atomic mass of 200X = 200.028
% abundance of 200X = 40% = 40/100 = 0.4
Atomic mass of 210X = 210.039
% abundance of 210X = 100% - 40% = 60% = 60/100 = 0.6
Average atomic mass of X = (0.4×200.028) + (0.6×210.039) = 80.0112 + 126.0234 = 206.0346
Answer:
B
Explanation:
The nucleus is made up of protons and neutrons, and electrons float around the neucleus in the electron cloud.
Answer:
Amino acids and proteins are the building blocks of life. When proteins are digested or broken down, amino acids are left. The human body uses amino acids to make proteins to help the body: Break down food.
The variables which are involved in understanding Kepler's third law of
motion are
<h3 /><h3>What is Kepler's third law of motion?</h3>
Kepler's third law of motion states that the the square of the orbital period of
a planet is proportional to the cube of the semi-major axis of its orbit. He
also inferred that the greater the distance, the slower the orbital velocity.
This thereby makes option D the most appropriate option as it contains the
orbital velocity and distance to sun variables.
