Answer:
262.5 Nm
Explanation:
Torque is the rate of change of angular momentum.
Hence, we have
Δ<em>L</em> is the change in angular momentum.
Using values in the question,
Answer:
(a) 108
(b) 110.500 kW
(c) 920.84 A
Solution:
As per the question:
Voltage at primary, (rms voltage)
Voltage at secondary, (rms voltage)
Current in the secondary,
Now,
(a) The ratio of secondary to primary turns is given by the relation:
where
= No. of turns in primary
= No. of turns in secondary
≈ 108
(b) The power supplied to the line is given by:
Power, P =
(c) The current rating that the fuse should have is given by:
Answer:
The minimum time to get the car under max. speed limit of 79 km/h is 2.11 seconds.
Explanation:
isolating "t" from this equation:
Where:
a= (negative because is decelerating)
First we must convert velocity from km/h to m/s to be consistent with units.
So;
