Answer:
Zero
Explanation:
here, the inductive reactance and the capacitive reactance is same, so this is the condition for resonance.
In the condition for resonance,
the circuit and the voltage in the circuit is in the same phase and the impedance of the circuit is minimum which is equal to the resistance of the circuit.
The phase angle is given by
Ф = 0
Explanation:
It is known that relation between torque and angular acceleration is as follows.
and, I =
So,
= 4
So,
= 1
as
=
Hence,
Thus, we can conclude that the new rotation is times that of the first rotation rate.
