Explanation:
No of electrons,
Time, t = 3 ms =
We need to find the electric current. We know that electric charge per unit time is equal to the electric current.
q = ne (Quantization of electric charge)
So, the electric current is 0.96 A.
Answer:
(a) The final angular speed is 12.05 rad/s
(b) The time taken to turn 5.5 revolutions is 5.74 s
Explanation:
Given;
number of revolutions, θ = 5.5 revolutions
acceleration of the wheel, α = 20 rpm/s
number of revolutions in radian is given as;
θ = 5.5 x 2π = 34.562 rad
angular acceleration in rad/s² is given as;
(a)
The final angular speed is given as;
(b) the time taken to turn 5.5 revolutions is given as
