Question

work is when an object moves a distance due to a specific force.
in order for work to be done, the object must move a distance in the direction of the applied force.
the formula for work is: force distance = work
work is measured in newton meters, n·m.
which of the following is true about work?
work is measured in kilometers per second (k/s).
work is measured in feet per hour (f/hr).
work is measured in newton meters (n·m).

Explanation:

The text on the left - hand side of the image clearly states that "Work is measured in newton meters, N·m". Kilometers per second (k/s) is a unit of speed, and feet per hour (f/hr) is also a unit related to a rate (speed - like in a very slow context).

Answer:

Work is measured in newton meters (N·m).
