Answer:
The minimum inductance needed is 2.78 H
Explanation:
Given;
frequency of the AC, f = 26.5 Hz
the root mean square voltage in the circuit, = 41.2 V
the maximum current in the circuit, I₀ = 126 mA
The root mean square current is given by;
The inductive reactance is given by;
The minimum inductance needed is given by;
Therefore, the minimum inductance needed is 2.78 H
Answer:
(a)
(b)
Given:
Time period of Pulsar,
Equatorial radius, R = 15 Km = 15000 m
Spinning time,
Solution:
(a) To calculate the value of the centripetal acceleration, on the surface of the equator, the force acting is given by the centripetal force:
(1)
where
(2)
Now, from (1) and (2):
(b) To calculate the tangential acceleration of the object :
The tangential acceleration of the object will remain constant and is given by the equation of motion as:
where
u =
