Which of the following is the best prediction of what would happen if the distance across section 1 in the diagram were to decre
ase?
1. Frequency would increase
2. Energy would decrease
3. Wavelength would increase
4. Amplitude would decrease
1. Frequency would increase
2. Energy would decrease
3. Wavelength would increase
4. Amplitude would decrease
1 answer:
Answer:
Option (1)
Explanation:
Relation between wavelength and frequency of a wave is,
Wavelength (λ) ∝
That means wavelength is inversely proportional to the frequency of a wave.
When the wavelength of the wave is decreased, frequency of the wave will increase.
Therefore, if the distance across section 1 is decreased in the given picture,
wavelength gets decreased.
As a result frequency of the wave will increase.
Option (1) will be the answer.

Answer:
1.78 m upward
Explanation:
We can find the displacement of the volleyball by using the SUVAT equation:
where, assuming upward as positive direction:
u = 6.0 m/s is the initial velocity
v = 1.1 m/s is the final velocity
a = g = -9.8 m/s^2 is the acceleration of gravity
d is the displacement
Solving the equation for d, we find:
And since it is positive, the displacement is upward.
