Marcus plucks at an outstretched coil and observes the following wave motion. what is the motion of the particles in this kind of wave? the particles will move up and down over large areas. the particles will move up and down over small areas. the particles will move side to side over small areas. the particles will move side to side over large areas.

option C

Explanation:

When Marcus plucks an outstretched coil, the coli sets into wave like motion that is oscillates to and fro. The particles of the medium do not move along the wave but just vibrate sideways about a fixed position.

The particles would move side to side over very small areas. Such type of wave is known as mechanical wave. Sound wave is a mechanical wave. The particles vibrate in the direction of the motion of the wave. The wave carries forward the energy.

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
