Answer:

Longitudinal Mechanical Wave

Explanation:

Mechanical waves are the waves that require medium to propagate. And a longitudinal wave is a wave in which the vibration of the energy(here: mass specifically) is in the direction of propagation of wave.

Shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by supersonic aircraft, explosions, lightning, or other phenomena that create violent changes in pressure.

Shock waves travel faster than sound and their speed increases as the amplitude of the wave is increased but their intensity fades faster due to the fact that some of its energy gets expended in the form of heat due to the resistance of the medium.

A football field is about 100 m long. If it takes a person 20 seconds to run its length, how fast (what speed) were they running

leonid [27]

Answer:

Speed, v = 5 m/s

Explanation:

We have,

The length of the football field, l = 100 m

A person takes 20 seconds to run its length.

It is required to find the speed of the person with which he should run. The distance covered divided by time taken is called its velocity.

$v=\dfrac{d}{t}\\\\v=\dfrac{100\ m}{20\ s}\\\\v=5\ m/s$

So, the speed of the person is 5 m/s.
