I didn't know these questions sorry
Answer:
The atomic mass unit is 1/12 of an atom of carbon 12, and is a very small amount to represent in kilograms:

is atomic mass unit.
This is why the benefits of the atomic mass unit is that it makes the representation of atomic masses easier in terms of the simplicity of the numbers that are used to represent the masses. Also using the atomic mass unit it is easier to compare the masses of different atoms, These numbers would be very small and would require negative powers of 10 to represent them, so it is more convenient to use the atomic mass unit.
I was hoping that there would be some options to choose from in regards to this question. Since there are no options given, so i am giving the answer based on my knowledge and hope that it helps. The charge exchanged through contact is known as static charge of electrostatic charge. This charge is exchanged mostly through rubbing between two objects.
