Question

Which of the following quantities would be acceptable representations of weight? Check all that apply. a.12.0 lb b.0.34 g c.120 kg d.1600 kN e.0.34 m f.411 cm

Answer 1

a.12.0 lb; b.0.34 g; c.120 kg

Explanation:

To measure weight using the English system of measurements, we use ounces, pounds, tons, etc.

To measure weight using the metric system, we use grams, milligrams, kilograms, etc.

This means that pounds, grams and kilograms are all acceptable representations of weights.

Kilonewtons (kN) measure force, not weight.

Meters and centimeters (m and cm) measure length, not weight.

Answer 2

a.12.0 lb

d.1600 N

Explanation:

THe weight of objects is the force with which each object is attracted by the gravitational force where they are located, for example on earth gravitational force is equal to 9.81 m/
`s^(2)`, so an object that is 1 kg of mass, would have a weight of 9.81 Newtons, pounds are also a measure of force.
