The angle turned through the flywheel of a generator during a time interval t is given by theta = at + bt^3 -ct^4, where a, b, a

Answer:
α =
Explanation:
The angle, θ, has been given as:
θ =
To obtain angular acceleration, α, we have to differentiate the angle twice, with respect to time, t.
Differentiating once will yield the angular velocity, ω:
ω = dθ/dt =
This can then be differentiated to obtain angular acceleration:
α = dω/dt =

Answer:
The magnetic field is
Explanation:
From the question we are told that
The mass of the metal rod is
The current on the rod is
The distance of separation(equivalent to length of the rod ) is
The coefficient of kinetic friction is
The kinetic frictional force is
The constant speed is
Generally the magnetic force on the rod is mathematically represented as
For the rod to move with a constant velocity the magnetic force must be equal to the kinetic frictional force so
