Answer:
W=1.5×10⁸J
Explanation:
first change the km to m then you get 10000m
- W=Fd
- W=15000*10000
- W=1.5×10⁸J
A. I looked it up and it should be somewhere around A
The maximum speed of the face is determined as 6.75 x 10⁻⁵ m/s.
<h3>
Maximum speed of the face</h3>
v = fλ
where;
- f is frequency of the wave
- λ is the wavelength
<h3>Angular speed of the wave</h3>
ω = 2πf
v(max) = ωA
v(max) = 2πfA
where;
- A is amplitude of the wave
v(max) = 2π(215)(50 x 10⁻⁹ m)
v(max) = 6.75 x 10⁻⁵ m/s
Thus, the maximum speed of the face is determined as 6.75 x 10⁻⁵ m/s.

The answer is B this can be easily shown if you have ever gotten up on a bus its the same effect but if you have trouble just elimination works A and D are outrageous and wrong C i can see the confusion but a train or a bus making you go in motion but your body wants to keep moving so it keeps in motion
Light warms objects when it shines on them. Sound waves from a powerful stereo can make the floor vibrate. Water waves crash on the beach with force. These observations support the claim that waves transfer energy.
