Answer:
The angular velocity at the beginning of the interval is .
Explanation:
Given that,
Angular acceleration
Angular displacement
Angular velocity
We need to calculate the angular velocity at the beginning
Using formula of angular velocity
Where, = angular acceleration
= angular velocity
Put the value into the formula
Hence, The angular velocity at the beginning of the interval is .
Without wind, many of the trees and plants you see today would not be there. The wind blows seeds through the air, like wish flowers. Also, some electricity wouldn't work because some people's electricity comes from wind turbines. Wind turbines are generated by wind :)
THIS IS A PROBLEM OF PHYSICS MECHANIC, PLEASE READ CAREFULLY THE ATTACHED FILE.<span />
Answer:
We define voltage as the amount of potential energy between two points on a circuit. One point has more charge than another. This difference in charge between the two points is called voltage.
Answer:
5.74s
Explanation:
We can first solve for the initial angular velocity using the following formula
Where is the final angular velocity, is the angular acceleration and is the angular displacement
So for the wheel to get from 22.4 to -22.4 with angular acceleration of -7.8 then the time it takes must be
