Answer:
140 Hz
Explanation:
Frequency is the reciprocal of period hence f=1/T
Here, the frequency is 140 times per second hence the period will be 1/140= 0.0071428571428 s
Rounded off to 3 significant figures then the period is 0.00714 s or 0.714 ms
Otherwise, the frequency is already given as 140 cycles per second which is equivalent to 140 Hz

Answer:
Answer to the question is:
Explanation:
Direct Current:
It is that current where electrons circulate in the same amount and sense in time, that is, flowing in the same direction. Its polarity is invariable and causes a current of relatively constant amplitude to flow through a load. This type of current is known as direct current (DC), and is generated by a battery.
the current of electrons will leave the negative terminal of the battery, (because they repel each other and also repel free electrons in the copper conductor), and go to the positive terminal where there is a lack of electrons, passing through the circuit to which it is connected. In this way the electric current is produced.
Answer:
I=0.0361 kg.m^2
Explanation:
Torque is the rotational equivalent of a force
Torque= perpendicular distance r X Force F
Torque T = I(moment of inertia) X α (angular acceleration)
T= Iα
r= 0.0285m
F= 1.9 x 10^3
T=0.0285 x 1.9 x 10^3
T= 54.15Nm
I=T/α
I=54.15/150
I=0.361 kg.m^2
