<span>The turbine, since it is a rotary engine that turns into mechanical energy the energy of a stream of water, steam or gas. The basic element of the turbine is the wheel or rotor, which has blades, propellers, blades or hubs placed around its circumference, such that the moving fluid produces a tangential force that drives the wheel and turns it. This mechanical energy is transferred through an axis to provide movement of a machine, a compressor, an electric generator or a propeller.</span>

Answer:
20 Hz
15.8 times
Explanation:
A
Although the range of frequency for any human's ear is usually said to be between 20 Hz and 20 kHz. And since the question asked for the least intense frequency, that has to be 20 Hz. Essentially the frequency most people perceive the least intense sound is 20 Hz.
B
A 100-Hz sound must be 10^1.2 times or 15.8 times more intense compared to a 1000-Hz sound to be perceived as equal to 60 phons of loudness
