Question

1. what is a joule? 1 foot /lb 1 meter 1 meter per second squared 1 n-m

Explanation:

A joule is the SI unit of energy and work. Work is calculated as force times distance. In SI units, force is in newtons (N) and distance in meters (m), so 1 joule = 1 newton - meter (1 N-m). 1 foot/lb is a non - SI unit related to work in the imperial system, 1 meter is a unit of length, and 1 meter per second squared is a unit of acceleration.

Answer:

D. 1 N-m
