Answer:
The number of turns is 64.
Explanation:
Given that,
Magnetic field = 0.050 T
Area of coil = 100 cm²
Frequency = 60 Hz
Output voltage emf= 12 V
We need to calculate the number of turns
Using formula of induced emf
Hence, The number of turns is 64.
Answer:
Energy Ouput (Useful) / Total Energy Input = 4000 / 4800 = .833
E = 83% assuming 4800 is actually input to fan
Commercial airliners encounter very little turbulence above 25,000 feet because the air is so thin at altitudes above 25,000 feet that turbulence has much less effect. That is option A.
<h3>What is turbulence?</h3>
A turbulence is a sudden disturbance that an airline encounters when it hits a strong wind current that can push or pull the plane.
The depth at which the airline flies determines whether the turbulence will have little or more effects on it.
At altitudes above 25,000 feet the air is so thin and light than below 25,000 feet therefore, the airline will encounter little turbulence effect.
