The sound produced is called wheezing. It is somewhat like a whistle except it's more course and you don't do it voluntarily like whistling, but rather it occurs because of obstructions. It can be either vocally or you can hear it when there are nasal obstructions when you are breathing through your nose.

Answer:
a)
b)
Explanation:
Given that
Charge = q
Magnetic filed = B
Radius = R
We know that kinetic energy KE
----------1
m v² = 2 .KE
The magnetic force F = q v B
Radial force
For uniform force these two forces should be equal
q v B R =m v²
q v B R = 2 .KE
Now put the velocity v in the equation
Answer:
The position of the spring in terms of g, m & k is
Explanation:
Stiffness of the spring = k
Mass = m
When a mass m is attached with the spring then spring stretched. in that case the force exerted on the spring is equal to weight of the mass attached.
⇒ Force exerted on the spring F = k x
⇒ m g = k x
⇒
This is the position of the spring in terms of g, m & k.
Answer:
Since the waves must carry a great deal of visual as well as audio information, each channel requires a larger range of frequencies than simple radio transmission. TV channels utilize frequencies in the range of 54 to 88 MHz and 174 to 222 MHz. (The entire FM radio band lies between channels 88 MHz and 174 MHz.)
