Answer:
Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.
Explanation:
none
Refraction. refraction is always accompanied by a wavelength and speed change
Answer:
we need the graph to answer the question.
The work done by Sarah is 3000 J
Explanation:
The work done by Sarah in climbing the set of stairs up is equal to its change in gravitational potential energy, and it is given by:
![W=Fd](https://tex.z-dn.net/?f=W%3DFd)
where:
F is Sarah's weight
d is the vertical distance covered by Sarah
In this problem, we have:
F = 500 N is Sarah's weight
d = 6 m is the vertical distance covered by Sarah
Substituting, we find the work done:
![W=(500)(6)=3000 J](https://tex.z-dn.net/?f=W%3D%28500%29%286%29%3D3000%20J)
