The mechanical efficiency = actual work / ideal work
So ζ = 1540 / 1600 * 100% = 96.25%

Answer:
The speed stays constant after the force stops pushing.
Explanation:
Speed always stays constant when the force stops pushing it.
(A)
Explanation:
We can see that the resistors are connected in parallel so all of them have the same voltage of 100 V. We also know that
Since resistor Y dissipates 100 W of power, we can solve for the current as
