Answer:
The work done is 2800 Joules
Explanation:
When a force causes a body to move, work is being done on the object
by the force
Work is the measure of energy transfer when a force moves an object
through a distance
→ Work = Force × Distance
→ The SI unit for work is the joule (J)
A refrigerator of 700 N is lifted straight up a distance of 4 meters
We need to find the work done
→ The weight of the refrigerator is 700 N
→ The force = 700 Newtons
→ The refrigerator is lifted straight up 4 m
→ The distance = 4 meters
Substitute these values in the rule below
→ Work = Force × Distance
→ Work = 700 × 4 = 2800 Joules
<em>The work done is 2800 Joules</em>
