A. The vibrations of the fields are perpendicular to the direction in which the wave moves.
Answer:
F1 = G m1 m2 / R^2 force of attraction
F2 = G m1 m2 / (R/2)^2
F2 / F1 = 4 the force of gravity will be quadrupled
A device that uses electricity and magnetism to create motion is called a "Motor" (which converts electric energy into mechanical energy) & <span>In a reverse process, a device that uses motion and magnetism can be used to create "Electromagnetism".
In short, 1st Blank = Motor
2nd Blank = Electromagnetism
Hope this helps!</span>
In scientific notation", that number would be written as
6.81 x 10⁻⁴ .
