Awave travels at a speed of 74 m/s. if the distance between crests is 12 m,
what is the frequency of the wave? use f =

f = 6.17 hertz

Explanation:

A wave is said to be a disturbance  which travels through a medium. This disturbance that travels through the medium carries energy. Generally, it is a physical phenomenon that possess amplitude, wavelength and frequency.

Frequency = velocity / wavelength

F = v/∧

where

v = velocity

∧ = wavelength

v = 74 m/s

∧ = 12

wavelength is the distance between successive crest or trough.

F = v/∧

f = 74/12

f = 6.16666666667

f = 6.17 hertz

answer; /// i believe the name your looking for is called (plaque)or check good luck

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
