Question

Find the amplitude of the oxygen level fluctuations. A weight hanging on a spring will oscillate up and down about its equilibrium position after it is pulled down and released. This is an example of simple harmonic motion. This motion would continue forever if there were not any friction or air resistance. Simple harmonic motion can be described with the function y = A cos(t Squareroot k/m), where |A| is the amplitude, t is the time in seconds, m is the mass of the weight, and k is a constant particular to the spring.

Explanation / Answer

Amplitude is minimum value minus maximum value divided by 2 so here minimum value is 5 and maximum is 9

A = (9-5)/2 = 4/2 = 2

So amplitude is 2 mg/L
