which of the following is true about the mass of an object?
it is equal to its weight.
it is proportional to its weight.
it is always more than its weight
it changes at different locations.

The correct answer is "It is proportional to its weight."

Explanation:

Mass is the amount of matter that a body contains. Weight is the action exerted by the force of gravity on the body.

The mass of an object will always be the same, regardless of where it is located, because the amount of matter does not vary. Instead, the weight of the object will vary according to the force of gravity acting on it.

The mass is measured in kilograms (kg) and the weight is measured in newtons (N).

The weight is equal to the product of the object's mass and the value of the local gravitational acceleration:

P = m * g

It can be seen that the weight is proportional to the mass of the object.

your answer would be a. 12.5 kg

6.4 cm (max) - 25 cm (min)
