The efficiency of the turbine is 50%.
The given parameters:
- <em>Kinetic energy of the wind, E = 3000 J</em>
- <em>Output electrical energy, E(out) = 750 J</em>
- <em>Energy lost to heat, E(lost) = 750 J</em>
- <em>Kinetic energy of the turbine, E(in) = ?</em>
The kinetic energy of the turbine which is the input energy is calculated as follows;
E(in) = 3000 - (750 + 750)
E(in) = 1500 J
The efficiency of the turbine is calculated as follows;
Thus, the efficiency of the turbine is 50%.

Answer:
Only if the acceleration is uniform
Answer:
I think it is the last one
Hot air rising and cool air sinking.
Explanation:I am not 100% sure. I just think the hot air rises bc evaporation.
Good luck. : )
