Pitch
Explanation:
The pitch of a sound wave is the perceived frequency of a sound wave.
The quality of sound that makes it discernible to the ear is the pitch.
- Sound wave is a longitudinal wave that is transmitted by series of rarefaction and compression.
- Pitch helps to distinguish between the different sound qualities.
- Pitch is how high or low sound is perceived.

Explanation :
It is given that,
Diameter of the coil, d = 20 cm = 0.2 m
Radius of the coil, r = 0.1 m
Number of turns, N = 3000
Induced EMF, 
Magnitude of Earth's field, 
We need to find the angular frequency with which it is rotated. The induced emf due to rotation is given by :




So, the angular frequency with which the loop is rotated is 159.15 rad/s. Hence, this is the required solution.
Temperature, The highness, and the time.
Hope this helps!
C=
Radioactive "decay" means particles and stuff shoot OUT of a nucleus.
After that happens, there's less stuff in the nucleus than there was before.
So the new mass number is always less than the original mass number.
