The answer is (A.) 135.6 N

Here is the formula you will need to answer the question.
Formula:
Force(N) = Mass(kg) x Acceleration(m/s²)
or... F(N) = m(kg) x a(m/s²)
————
We need to be certain of the information presented. The problem says the man has a "Mass" of 83 kilograms on Earth. If a man has a Mass of 83 kilograms on Earth, he has a mass of 83 kilograms everywhere. The mass for this problem (even on the moon) is 83.
Mass(kg): 83
————
To find the acceleration of object on other planets, moons, ect, you'll need to search the internet or ask a teacher. There are ways to calculate this, but the problem didn't supply the necessary information to do so.
Acceleration: 1.625 m/s²
————
Now just plug the information into the formula.
F(N) = m(kg) x a(m/s²)
N = 83 x 1.625
N= 135.875
When considering that there could be a slighty more accurate number for acceleration, it can be concluded that the best answer is (A.)
Answer:
A.outer-shell electrons of one atom are transferred to the inner electron shells of another atom.
Explanation:
In covalent chemical bond, outer shell share pair of electrons to fill both atoms outer shell. Covalent bond can be polar and non-polar. Hydrogen and carbon bonding is example of non-polar bonds; while hydrogen bonding with chlorine is polar covalent bond example
