Answer:A piece of driftwood moves up and down as water waves pass beneath it. However, it does not move toward the shore with the waves. What does this demonstrate about the propagation of waves through a medium?
A) Waves transmit energy but not matter as they progress through a medium.
B) Waves transmit matter but not energy as they progress through a medium.
C) Waves do not transmit matter or energy as they progress through a medium.
D) Waves transmit energy as well as matter as they progress through a medium.

Answer:
The woman's average velocity during the trip is 36.2 miles/hour.
Explanation:
Velocity can be define as the displacement of an object per time. It is a vector quantity, and measured in m/s.
i.e velocity = 
From the given question,
Displacement = 
= 
= 
= 425
The displacement of woman is 425 miles.
velocity = 
= 36.1702 miles/hour
The woman's average velocity during the trip is 36.2 miles/hour.
Three complete orders on each side of the m=0 order can be produced in addition to the m=0 order.
The ruling separation is d=1/(470mm-1)

Diffraction lines occurs at an angle θ such that dsin=mλ,when λ is the wavelength and m is an integer.
Notice that for a given order,the line associated with a long wavelength is produced at a greater angle than the line associated with shorter wavelength.
we take λ to be the longest wavelength in the visible spectrum (538nm) and find the greatest integer value of m such that θ is less than 90°.
That is,find the greater integer value of m for which mλ<d.
since,d/λ

There are three complete orders on each side of the m=0 order.
The second and third orders overlap.
