Mark is pushing a box down the hall. Mark is using 5N to push the box 20m. How much work is Mark doing?

Explanation:

The work done by an object can be found by using the formula

From the question

force = 5N

distance = 20m

We have

workdone = 5 × 20

We have the final answer as

Hope this helps you

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy

hope that                                         : )

the higher the current the higher the mag field around it the higher the influence on the compass
