Answer:
a. the desired signal is 90 degrees out of phase with the intelligence signal.
Explanation:
The signal to noise ratio of FM detector is defined as function of modulation index for SSB FM signal plus narrow band Gaussian noise at input. The ratio is usually higher than 1:1 which indicates more signals than noise.
1.) A semiconductor is a device whose conductivity lies between the conductivity of the conductors and the insulators.
2.) A Zener diode is a semiconductor device made of silicon that allows current to flow in both directions.
<h3>What is a semiconductor?</h3>
A semiconductor is a device whose conductivity lies between the conductivity of the conductors and the insulators.
Due to the inclusion of an impurity or temperature effects, a solid substance with conductivity between that of an insulator and that of most metals. Semiconductor devices, particularly silicon devices, are key components of most electronic circuits.
Zener diode:-
A Zener diode is a semiconductor device made of silicon that allows current to flow in both directions.

Answer:
7.72 seconds
The answer is not realistic as the time is very less to reach to a speed of 100 km/hr
also, we have not taken other factors into consideration like wind drag etc.
Explanation:
Data provided in the question:
Mass of the engine = 1500 kg
Power rating = 75 kW = 75,000 W
Initial speed, v₁ = 0
Final speed = 100 km/hr = = 27.78 m/s
Now,
Power = Work done ÷ Time
also,
Work done = Final energy - Initial energy
=
=
= 578703.70 J
thus,
75,000 = 578703.70 ÷ time
or
time = 7.716 s ≈ 7.72 seconds
The answer is not realistic as the time is very less to reach to a speed of 100 km/hr
also, we have not taken other factors into consideration like wind drag etc.
Answer:
Applied pressure on piston (P) = 50 psi. We know that work done is given by W = Force x displacement. S Force = Pressure x Areas > W = ( PXA ) X L W = PX ( AL ) W = PX AV = 50x 43.7088. W= 2185.

Answer:
zero off your workpiece so you can work from a datum, usually the centre of your work on a lathe. change your tool to a drill and drill a hole to a size smaller than your thread diameter, change out your tool for a threaded tap and away you go.
I'm not sure which part they want but I'd say ensure your tool is set to the right height, you have the tool lines up where you want to cut and that you have calculated the speed you need to cut at safety. Drill a hole before you tap though.
If you have a CNC lathe you just set the programme to do the processes and tool change for you.
