Answer:
400 N
Explanation:
Due to action-Reaction, the wall pushes back on the person with a force of equal magnitude and in opposite direction to the force exerted by the person.
So the magnitude must be also 400 N.

Use P=F/a
whereas P= 350000 and a=.9m2
substitute into the formula we get
350000=f/.9m2 multiply .9 on both sides as LHS=RHS WE get 315000 Newtons as the answer
<h3>Answer;</h3>
<em>Energy is transferred.</em>
<h3>Explanation;</h3>
- Work is the force applied over a given distance, in other words work is the product of force and distance. That is; Work = force × distance.
- Work is measured in Joules.
- Energy on the other hand, is the ability to do work.
- According to the principle of work-energy a change in the kinetic energy is equivalent to the net work don e by the object. Therefore, when work is being done energy is being transferred from one point to another.
A philosophical theory or approach that emphasizes that the existence of the individual person as a free and responsible agent determining their own development through acts of the will.
