Answer:
(a) 0.81 V
(b) 0.52 V
Explanation:
Number of turns, N = 150
Radius, r = 2.5 cm = 0.025 m
Magnetic field, B = 0.060 T
f = 440 rev/min = 440 / 60 = 7.33 rps
A.
The maximum emf is given by
e = N x B x A x 2 x π x f
e = 150 x 0.060 x 3.14 x 0.025 x 0.025 x 2 x 3.14 x 7.33
e = 0.81 V
B.
The back emf is given by
e' = 2e / π = 2 x 0.81 / 3.14 = 0.52 V
It’s a dynamic load.
Hopes this helps :)
Answer:
C
Explanation:
becauase i just tooke the test
Rutherford was the first person to make a model of an atom that was mostly accurate, the only thing is in his early model there were electrons and protons, at this time Rutherford did not know of a neutron and was not discovered until 1932.<span />
Yes they are equivalent because 7x5=35 and 8x x 5=48x
