The most appropriate answer is A, the the start winding on a split-phase motor is to provide a starting torque. A split-phase motor is a single phase electrical motor (common in many household applications such as washing machines and household fans), with two distinct windings on the stator coils, the start windings and the run windings, at 90 degrees apart. When the motor is energised the start coils acts like a second phase (2 phase motor) and helps provide the rotating magnetic field that is necessary to turn the rotor. Once moving, only the run winding (single phase) is required to keep the motor spinning.
The other answers are irrelevant for the starting of the motor.

Answer:
import math
l = float(input("Enter length in cm: "))
l = l / 100;
print("Entered length is " + str(l) + " meters")
area_square = l * l
print("Area of square is " + str(area_square))
area_circle = math.pi * l/2 * l/2
print("Area of circle is " + str(area_circle))
volume_cube = l * l * l
print("Volume of cube is " + str(volume_cube))
Explanation:
*The code is in Python
Ask the user to enter the length in cm
Convert the length to meters and print it
Calculate the area of the square and print it (Since length is equal to a side, the area is length * length)
Calculate the area of the circle and print it (Since length is equal to the diameter, you need to divide it by two to get the radius. The area is pi * length/2 * length/2)
Calculate the volume of the cube and print it (Since length is equal to a side, the volume is length * length * length)
