The answer to your question is AB is 50 kilometers.
50 kilometers
Answer:
2649600 Joules
Explanation:
Efficiency = 40%
m = Mass of air = 92000 kg
v = Velocity of wind = 12 m/s
Kinetic energy is given by
The kinetic energy of the wind is 6624000 Joules
The wind turbine extracts 40% of the kinetic energy of the wind
The energy extracted by the turbine every second is 2649600 Joules
D. The maximum electromotive force induced in the coil is determined as 3,200 V.
<h3>
Maximum electromotive force induced in the coil</h3>
emf(max) = NAB/t
where;
- N is number of turns
- B is magnetic field
- A is area of the coil
- t is time
Substitute the given parameters and solve for emf
emf(max) = (150 x 0.042 x 0.86) / (1.7 x 10⁻³)
emf(max) = 3,187.1 V
emf(max) ≈ 3,200 V
Thus, the maximum electromotive force induced in the coil is determined as 3,200 V.
