Question

ten seconds after an electric fan is turned on,the fan rotates at 300rev/min.its average angular acceleration is​

Answer 1

Answer:see the attachment

Explanation:

Answer 2

The final angular velocity of the fan after 10 seconds is 31.4 radians/second. The average angular velocity of the electric fan after 10 seconds is approximately 3.14 rad/s.

To calculate the average angular acceleration of the electric fan, we need to know the initial angular velocity of the fan and the final angular velocity after 10 seconds. Since the initial angular velocity is not given, we cannot calculate the average angular acceleration.

However, we can calculate the final angular velocity of the fan after 10 seconds, which is 300 revolutions per minute (rev/min). To convert this to radians per second, we can use the conversion factor 2π radians per revolution:

= 300 rev/min x (2π radians / 1 revolution) x (1 minute / 60 seconds)

= 31.4 radians/second

To calculate the average angular velocity, we can use the formula:

average angular velocity =

(final angular velocity - initial angular velocity) / time

In this case, the initial angular velocity is 0 rad/s, the final angular velocity is 31.4 rad/s (calculated in the previous answer), and the time is 10 seconds.

Substituting the values, we get:

average angular velocity = (31.4 rad/s - 0 rad/s) / 10 s

average angular velocity = 3.14 rad/s
