What is the average atomic mass (in amu) of element M?

1 answer:

4 0

An atomic mass unit (symbolized AMU or amu) is defined as precisely 1/12 the mass of an atom of carbon-12. The carbon-12 (C-12) atom has six protons and six neutrons in its nucleus. In imprecise terms, one AMU is the average of the proton rest mass and the neutron rest mass.

Which of the following is not an appropriate unit for momentum?

ioda

Answer: Option (c) is the correct answer.

Explanation:

Momentum is the product of mass and velocity.

Mathematically, p = m × v

where p = momentum

m = mass

v = velocity

It is known that mass can be measured in Kilograms or grams. Whereas velocity is measured in meter per second or centimeter per minute or hour.

On the other hand, unit kilometer is a unit of distance and not mass.

Thus, out of the given options km.m/s is not an appropriate unit for momentum.
