Answer:
525.2
Explanation:
w = 154 rad/s, e0 = 16.5 V, A = 1 x 3 = 3 cm^2 = 3 x 10^-4 m^2, B = 0.68 T
Let the number of turns be N.
By use of law of electromagnetic induction
e0 = N B A w
16.5 = N x 0.68 x 3 x 10^-4 x 154
N = 525.2
Answer:
True
Explanation: due to the high leg,
It has to be grounded in order to stabilize the high alternating current voltage providing an alternative route for current to flow into the ground. and also protect it from lightening and thunder.
Just gonna grab some points by answering this. Have a good day!
Answer:
It will take 40 seconds to catch the speeding car
Explanation:
Initial speed of the patrolman = 55 mph
after one minute speed of patrol man = 115 mph
now acceleration of patrolman is given by


now at this acceleration the distance covered by patrolman in "t" time is given as


now we know the speed of the speeding car is given as

now in the same time distance covered by it

now since the distance covered is same
