Answer:
Electric motors build energy through the interaction between magnetic fields.
Magnetic fields may be generated by passing a current through a wire. Winding that wire into a coil intensifies the sector. Wrapping the coil around an iron core can intensify it more. One is going to be of the coil are North, the other South. Reverse the flow of current through the coil. The magnetic poles can swap. Place 2 separate coils close to one another and organize them therefore one turns whereas the opposite is fastened. Then build arrangements for this within the moving coil to reverse even as the opposite poles are about to line up.

Answer:
B because the earth rotational axis tilt away from the sun.
The mechanical advantage of the lever is 3 and the right option is A.) 3.
<h3>What is mechanical advantage?</h3>
Mechanical advantage can be defined as the ratio of load to effort in a machine.
To calculate the mechanical advantage of the lever, we use the formula below.
Formula
- M.A = y/x................ Equation 1
Where:
- M.A = mechanical advantage of the lever
- y = distance moved by effort (input arm)
- x = distance moved by load (output arm)
From the question,
Given:
Substitute these values into equation 1
Hence, The mechanical advantage of the lever is 3 and the right option is A.) 3.
