Answer:
Option A
Explanation:
From fundamental equation of motion
where v is the final velocity, u is the initial velocity, a is the acceleration of the body and s is the displacement.
Since the initial velocity is zero
Making acceleration, a the subject of the formula then
Substituting 5 m/s for v and 2.5 m for s then
B is a trough.
A trough is the opposite of a crest, in that it occurs at the maximum negative displacement of a wave.
In this problem, A would be the crest, C would be the wavelength, and D would be the amplitude.
Hope this helps!! :)
Answer:
They fold to create ridges and valleys perpendicular to the direction to which pressure is applied.
