Answer:
ultrasound: high pitch, above the human range of hearing, reflects back
infrasound: longitudinal waves, in the human range, low pitch
Explanation:
Answer:
= 2 beats per seconds
Explanation:
- From |f -f'| = modulus of the difference between the frequency given.
- Difference between the frequency will give us the number of beat per seconds.
These also shows how to get the period of the tuning forks.
W = F * s
Here, F = 50 N
s = 15 m
Substitute their values,
W = 50 * 15
W = 750 J
In short, Your Answer would be 750 Joules
Hope this helps!
The energy travels in a disturbance, in an ocean that disturbance is a wave, so the wave makes energy and moves it through the water
