Question

Two descriptions about physical quantities are given below: Quantity A: It is unaffected by the location of an object in space. Quantity B: It can be measured in kilograms. What quantities are these most likely describing?

a.  Both Quantity A and Quantity B are mass.
b.Both Quantity A and Quantity B are weight.
c. Quantity A is weight and Quantity B is mass.
d. Quantity A is mass and Quantity B is weight.

Answer 1

I would base my answer on the choices. There are only two parameters mentioned: mass and weight. Mass is constant regardless of the the location. So, definitely it is neither Quantity B nor Quantity A. Weight, on the other hand, is a consequence of gravitational force. Since gravity is different in the moon and the Earth, weight varies. Thus, the answer is B.

Answer 2

Option A, Both Quantity A and Quantity B are mass

Step-by-step explanation:

Mass is the total amount of matter contained in an object or substance and it remains the same irrespective of any external factor such as gravity.

This means that an elephant which has a mass of 100 kg on earth has a mass of 100 kg on moon or any other planet.

Since mass can be measured in kilogram, option A is the most suitable answer.
