<u>Compression - "</u>Compression is a process in which the actual space covered by any sort of entity is reduced and the values of the given parameters are lowered."
Explanation:
<u>Definition with respect to Stress and strain-</u> "The change in actual length,L to a new length,ΔL due to applied stress is called as compression".
<u>Definition with respect to longitudinal wave-</u> "The region of the wave where the particles present are more close to each other is called as compression".
<h3><u><em>Compression. A compression is a region in a longitudinal wave where the particles are closest together. Rarefaction. A rarefaction is a region in a longitudinal wave where the particles are furthest apart.</em></u></h3>
Answer: For me personally i have a Biblical faith and first of all there is evidence that looks convincing that the big bang made the universe, but man wants answers and God in the Bible says he created the universe for us it is hard to believe it but i have faith.
Applying the work-energy theorem, if we can neglect the friction between truck and road, the total change in kinetic energy must be equal to the work done by the external forces.
This work, is just 4,475 J.
So we can write the following equation:
where m= mass of the truck = 2.5*10³ kg.
So, we can find the speed v, as follows:
b)
The work done by the man, is just the horizontal force applied, times the displacement produced by the force horizontally:
