Answer:489 Revolutions
Explanation:
Given
Angular deceleration
Given wheel angular velocity =96 rad/s when machine is turned off
time taken by machine to reach zero angular velocity
0=96+(-1.5)t
t=64 sec
angular displacement is given by
For revolutions =
The answer is a,(what is the velocity of the current
Answer:
The strength of magnetic field is 0.25 T
Explanation:
Time period sec
Mass of proton kg
Charge of proton C
Here proton moves in circular path
Velocity of proton is given by,
Put the value of velocity in above equation,
Now magnetic field is given by,
T
Therefore, the strength of magnetic field is 0.25 T
