Aplatform oscillates in the vertical direction with shm. its amplitude of oscillation is 0.20 m. what is the maximum frequency (hz) of oscillation for a mass placed on the platform to remain in contact with the platform?

The maximum frequency is 1.114 Hz.

Explanation:

Given that,

Amplitude = 0.20 m

We need to calculate the maximum frequency

Using formula of frequency

Where, a = amplitude

g = acceleration due to gravity

Put the value into the formula

Hence, The maximum frequency is 1.114 Hz.

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
