Answer:
Wavelength.
Explanation:
1 period, or wavelength, is measured from one crest to another or from one trough to another.
Planets orbit the sun in the paths which are known as elliptical orbit. Each planet has its own orbit around the sun and direction in which all the planets orbit around the sun are the same. These orbits were well explained by the astronomer Kepler. The gravity of the Sun keeps the planets in their orbits. They stay in their orbits because there is no other force in the Solar System which can stop them.
Answer:
Explanation:
The Coulomb's Law gives the force by the charges:
Let us denote the positon of the charge q on the y-axis as 'y'.
The force between 'Q' and'q' is
where Θ is the angle between 
and x-axis.
whereas
Finally, the x-component of the net force is
