How much work is done by a man who uses a force of 7 newtons to push a box 3 meters across the room? explain.

The formula to calculate work done is -

Work done ( in joule, J) = Force (in Newton) X Distance (in meters)

So, we will use the formula to calculate work done,

Here, force is given as = 7 newtons

Distance is given as = 3 meters

So, work done will be -

Work done ( in joule, J) = 7 Newtons X 3 Meters

Work done ( in joule, J) = 21 J (in joule)

for the first question it would be the second answer for the second question it would be the third answer and for the third question it would be the first answer

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
