At its peak, a tornado is 74.0 m in diameter and carries 335-km/h winds. What is its angular velocity in revolutions per second?

0.399 rev/s

Explanation:

Given that,

The diameter of a tornado, d = 74 m

Radius, r = 37 m

Linear velocity, v = 335 km/h = 93.05 m/s

We need to find the angular velocity in revolutions per second. Let it is . The relation between angular velocity and linear velocity is as follows :

or

So, the angular velocity of the blade is 0.399 rev/s.

c)as speed changes, wavelength and frequency change.

everything changes!
