Answer:
The correct options are;
Mechanical
Faraday
Explanation:
The principle of working of electric generators is to convert kinetic energy, which is the energy present in the spinning turbine into electrical energy. Electricity is generated by the use of the electric generators has the largest share of all forms of electricity generated electricity and it is based on Faraday's law of of induction, which states that Emf = N×(ΔФ/Δt)
Where;
Emf = The induced voltage
ΔФ = Change in magnetic flux
Δt = Change in time.
Therefore, we have;
Traditional power-generating stations do not store electrical energy. In such power stations, the original energy source spins a turbine which an electric generator. It converts <u>mechanical </u>energy into electrical energy using a fundamental principle of physics called <u>Faraday's</u> law.

Answer:
15.7 ; 78.5
Explanation:
Mechanical advantage of a screw = Circumference / pitch
Circumference = pi × d
Where :
pi = 3.142, D = diameter
Therefore ;
Circumference = 3.142 × (1/4) = 0.785 in
Pitch = 1/TPI
TPI (thread per inch) = 20
Pitch = 1/ 20 = 0.05
Mechanical advantage = 0.785 / 0.05 = 15.7
Resistance force if effort force is 5lb
Mechanical advantage = Fr / Fe
Fe = effort force, Fr = resistance force
15.7 = Fr / 5
Fr = 15.7 × 5 = 78.5 lbs
