No, and the actual percentage is disputed and varies greatly.

It depends on how it is designed.But most of them are generally not accurate. For example one such lie detector works on the principle of conductivity of our body.Generally resistance of our body is very high.When we lie we swet(may not be externally but surely our glands swet).Since water conducts electricity the resistivity decreases and so lie is detected. But this is not always true.resistivity of people vary and so it cannot give accurate results always. In the same way each method has its own limitations.
answer for me please
Distortion.
there are two types:- 1) simple diode detector 2) practical diode detector the diode is common device used in am demodulator. signal(am demodulator signal ) is applied anode and output is taken from cathod
a device which output voltage is almost the real peak valueof an applied signal
The time constant in an envelope detector affects the speed at which the detector can track changes in the input signal. A longer time constant results in smoother output but slower response to changes, while a shorter time constant provides faster response but may introduce more noise in the output signal. Balancing the time constant is important for optimizing the performance of the envelope detector.
Both output and outputs is correct, although in American English the word output is used.
The circuit that generates signal having the shape like imaginary curve is called an envelope detector. The effect of the time constant RC in envelope detector is that the output follows the input curve and the circuit performs like a demodulator.

Yes, that's correct. When the work input to a machine equals the output work, the machine is considered 100 percent efficient. This means that all the energy put into the machine is transformed into useful work without any energy being wasted or lost.
