Answer:

We can use the formula w = mg, where w is weight, m is mass, and g is acceleration due to gravity (which is approximately 9.8 m/s^2 on Earth).

Given that an object whose mass is 4kg weighs 12N, we can find g as:

w = mg

12 = 4g

g = 3

Now, we can find the weight of an object whose mass is 7kg as:

w = mg

w = 7 x 3

w = 21N

Therefore, an object whose mass is 7kg weighs 21N.
