13. which statement accurately describes the relationship between mass and weight?
a. an object with twice the mass of another object will weigh twice as much

the correct option is A.

Explanation:

Weight = Mass X Acceleration due to gravity(10m/s2)

If A has a mass of 4Kg and the mass of B is twice that of A. Then their weight will be :

For A:

W = 4 x 10 = 40N

For B:

Mas of B is two times that of A i.e

2 x 4 = 8kg

W = 8 x 10 = 80N

Comparing the weight of A and B it is clear that the weight of B is also twice the weight of A
