The wavelength<span> can always be determined by </span>measuring<span> the distance between any two corresponding points on adjacent </span>waves<span>. In the case of a longitudinal </span>wave, awavelength measurement<span> is made by </span>measuring<span> the distance from a compression to the next compression or from a rarefaction to the next rarefaction.

Answer:
2632 foot-pound
Explanation:
Work done: Work is said to be done when ever a force moves a body through a given distance. The S.I unit of force is Newton (N).
From the question,
The expression for work done is given as,
W = Fdcos∅......................... Equation 1
Where W = work done, F = force, d = distance, ∅ = angle between the force and the horizontal.
Given: F = 32 lbs, d = 90 feet, ∅ = 24°
substitute into equation 1
W = 32×90×cos24
W = 2880(0.914)
W = 2632.32
W = 2632 foot-pound
Answer:
0(zero)
Explanation:
Given that 
=0.20kg, radius of the bowl,
and that the mass slides from point A to B.
-Since the normal force is perpendicular to the displacement at every point of the motion,then work done by the normal force is zero.
