Question

A student claims to have a weight is 45 kg What is the problem with the claim?

Most people way more than 45 kg

most people weigh less than 45 kg

kg is a unit of mass in the SI system so she has confused mass and weight

the student has confused kg with newtons and must weigh 45 N

Answer 1

Kg is an SI unit for mass. So in order to get weight, you’d have to times Kg by gravity.

So I think it’s C.

I hope that helps.

Answer 2

Answer:

kg is a unit of mass in the SI system so she has confused mass and weight

Explanation:

Kilograms are the SI unit for mass, and Newtons are the SI unit of weight.  Therefore, the student needs to reevaluate their claim by using N instead of Kg.
