Question

The magnitude of the weight of a 3.0 kg object on the surface of the earth is 29 N. True False

Answer 1

True

Step-by-step explanation:

3.0 * 9.8 = 29 N

Answer 2

True

In fact, the weight of an object on the surface of the Earth is given by:

`F=mg`
where m is the mass of the object and
`g=9.81 m/s^2` is the gravitational acceleration on Earth's surface. If we use the mass of the object, m=3.0 kg, we find

`F=mg=(3.0 kg)(9.81 m/s^2)=29 N`
