In a longitudinal wave, the motion of the medium is parrellel to the direction of the wave.
<h2>Positive Affects:</h2>
- Technology aids in the research of curing diseases or other environmental problems. Without technology, we would not have been able to eradicate diseases like polio.
- Technology allows us to communicate to people quicker, in spite of the distance and conditions.
<h2>Negative</h2>
- Over-dependence of technology makes humans lazy. We won't be paying much attention because everything is available on Google.
- There are health affects due to the radiation. Our vision gets weakened and the laziness can lead to physical problems like obesity and fatigue.
it is easier to thrust a magnet into a wire coil with one loop than one with four loops Because with four loops it becomes more difficult to push the magnet in.
<h3>What is a magnetic field?</h3>
It is the type of field where the magnetic force is obtained. The magnetic force is obtained it is the field felt around a moving electric charge.
The quantity of turns or loops in a coil directly relates to the intensity of the magnetic field within the coil.
As a result, the magnetic field strength has increased fourfold when there are four loops instead of one, making it more difficult to push the magnet in.
A single-looped wire coil is simpler to insert a magnet into than one with four loops. because inserting the magnet gets more challenging when there are four loops.

Answer:
(1) weight = 565N
distance = 325m
time= 12.6s
power = work done/time
work done= force * distance
= 565*3.25 =1836.25
:. power = 1836.25\12.6
=145.7!
(2) the books will add more to her weight and thereby increasing her power output.
