What quantity measures the number of complete cycles an oscillation makes per second?

Frequency

Explanation:

A periodic oscillation can be described by using different quantities. The most important are:

- Amplitude: the maximum displacement of the oscillation, relative to its equilibrium position

- Period: the time it takes for the system to complete one full oscillation

- Frequency: the number of complete cycles the oscillation makes per second

From the definitions above, we see that the quantity that the problem is asking for is the frequency. Frequency is also related to the period by the equation

where T is the period of oscillation.

the answer is a 3.8cm

explanation:

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
