Power is the rate of generating, moving, or using energy.
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
Answer:
140.85 is the correct answer
The correct answer is the Sun.i hope that helped! if you have any questions or concerns about the answer i gave you please let me know!!
Answer:
Explanation:
2F-F=ma, so F=ma or .17=(13x10-3kg)a then a=13.07m/s2
