The blades on a fan rotate at 750 revolutions per minute and have a diameter of 16 inches. Find the angular velocity of a fan blade and the linear speed of a point on the tip of the fan blade. Use 3.1416 as the value of pi.

Angular velocity 78.5

The value of liner speed of a point on the tip of the fan blade V = 16

Explanation:

Given data

N = 750 R.P.M

D = 16 in = 0.4064 m

R = 0.2032 m

Angular velocity of a fan blade is given by

Put all the values in above formula we get

78.5

The linear speed of a point on the tip of the fan blade is given by

V = R

V = 0.2032 × 78.5

V = 16

This is the value of liner speed.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
