The table shows the values of two quantities for an astronaut on Earth and Jupiter.
Astronaut's Details
Earth
Jupiter
Quantity A 705.6 units 1,868.4 units
Quantity B 72 units
72 units
Which of the following names the quantity and correctly explains why that represents the amount of matter present in the astronaut?
O Quantity A, because it is proportional to mass
O Quantity A, because it changes with gravitational pull
O Quantity B, because it is the gravitational pull exerted
astronaut
O Quantity B, because it is independent of the astronaut's location in space

Answer 1

Quantity A because it changes with gravitational pull.

Explanation:

Mass defines the constitutive matter of an object. It is immutable (does not change). Although it could be converted into energy, the matter is constant.

On the other hand, the weight of an object (gravitational force) depends on the acceleration due to gravity.

That is why an astronaut weighs about three times more on earth than on Mars. The gravitational acceleration on Mars is about one third that on earth.
