1.93 x 10∧3 N
Explanation:
The picture attached shows the calculation
The answer is actually 1 & 17, maybe you meant to put 1&17 as option b
Answer:
Part 1) Voltage in secondary windings is 61.08 Volts
Part 2) Current in secondary windings is 0.53 Amperes
Explanation:
The potential developed in the primary and secondary winding of a transformer are related as

where
Np no of turns in primary coil
Ns no of turns in secondary coil
Vp Voltage of turns in primary coil
Vs Voltage of turns in secondary coil
Applying values in the formula we get

Part 2)
Using Ohm's law the current is given by

Answer:
Grams, I believe..! (Meter, liter, gram)
If the input machine produces an
output of 80 Newtons, then the mechanical advantage is that it produces work. If
the required output must be 80 Newtons, then the input force is desirable
having 100 percent production of force even though it requires a large amount
of input to produce 80 Newtons of force.
