Answer:
Yes
Explanation:
Newton's third law
For every action, there is an equal and opposite reaction.
SO if the apple is falling 9.8 m/s2 then the same force is pushing against it.

"D. Magnetic and electrical forces are similar because they are both related to the interactions between charged particles" best describes how the forces relate.
The pressure of nitrogen which is needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).
<h3>What is pressure? </h3>
It is defined as the continuous physical force applied on or against an object by something which is in contact with it.
It is also defined as the force per unit area.
<h3>What is henry's law? </h3>
The henry law constant is thr ratio of the partial pressure of compound in air to the concentration of compound in water at given temperature.
C= kp
where,
C is the concentration of compound = 0.53m
k is the henry constant = 6. 2×10−4matm
p is the pressure of compound
By substituting all the value we get,
C = 6. 2×10−4 × p
0.53 = 6. 2×10−4 × p
p = 0.53/6. 2×10−4
p = 3.2 × 10^(4)
Thus we find that the pressure needed to maintain a N2 concentration of 0. 53 m is 3.2 × 10^(4).

As we know that work done is defined as product of force and displacement in the direction of applied force
so we can say it is
or we can say
so we will have following options
A)Pushing against a locked door
There is no work done in above case as there will be no displacement in that case so work done is ZERO
B) Carrying a box down a corridor
While we move done and carrying a box then work done by gravity on the box while our work done is negative work.
C) Pulling a trailer up a hill
In above case our work done to pull a box up a hill is positive work as we need to work against gravity
D) Suspending a heavy weight with a strong chain
During suspension there is no displacement so there will be no work done in above case
so correct answer will be
<em>Pulling a trailer up a hill</em>
