Answer:

Ratio of the amplitude of two given SHM is 1.414 : 1

Explanation:

As we know that we have two SHM equations given here

so for the first SHM we have

x_1 = 4 sin 2\pi t

so amplitude of the above motion is

A_1 = 4

for another SHM we have

x_2 = 2(sin2\pi t + cos2\pi t)

so we can write it is

x_2 = 2\sqrt2 sin(2\pi t + \frac{\pi}{4})

so the amplitude of this motion is

A_2 = 2\sqrt2

now the ratio of the amplitude of the two motion is given as

A_1 : A_2 = 4 : 2\sqrt 2

A_1 : A_2 = 1.414 : 1
