Answer:
Waves have many properties, including frequency, wavelength, amplitude, timbre, and direction. ... A higher frequency sound is perceived as a higher note, because frequency is the same thing as pitch. The amplitude is how tall the wave is. A higher amplitude sound wave is a louder sound.
Explanation:
Answer:
There are many ways to compare waves and how they change direction. The most common way is through the wind. This is different from human force because of direct contact in the wind and human force. However they both intact something physically moving the ocean. This compares how different waves move.

Answer:
f = 3.97 Hz
Explanation:
Given that,
Centripetal acceleration,
The radius of motion is 0.02 m
The formula for the centripetal acceleration is given by :
The speed of an object in a circular path is given by :
t is time period
Also, f=1/t (f is frequency)
Hence, the frequency of motion s 3.97 Hz.
Answer:
Explanation:
In a rotating system , when a torque is applied , angular acceleration or deceleration takes place . The child is walking towards the center . He must be applying force on the ground . In return , ground must be applying reaction force on him which helps him to go towards the center . These two force of action and reaction are internal forces . One will increase the angular momentum of one and the other force will decrease the angular
momentum of other . But total angular momentum of the whole system will remain constant . So angular momentum will be conserved.
A tornado is a natural force It is a very strong wind that causes thing to damage
