We call it differential rotation when parts of a body move at different speeds. This is true of the gas giants, and of the sun, too.
It varies. The planets move in their orbits at different distances from the sun and at vaying speeds. The distances between them is constantly changing.
They all move at the speed of light. Wavelength varies, but the speed is the same.
It means they spin. They turn in space, pivoting around an invisible axis that runs from pole to pole through each planet. Different planets spin at different speeds, and their spins are not perfectly aligned with their orbits (revolution) around the Sun. The spin or rotation of the Earth is what makes the Sun appear to move across the sky.
No only when in earth's atmoshpere can the gravity be on.
A year is different on each planet because the planets move at different speeds (e.g. Earth takes 365 and a a quarter days to spin around the sun once and Mercury takes 88 days to orbit on its axis.
Yes.
The question is meaningless; different dwarf planets move at different speeds.
The planets move on little circles that move on bigger circles.
They move at different speeds.
No. All sound waves in the same air move at almost exactly the same speed. If different frequencies moved at different speeds, then live orchestras, choruses, and bands would be impossible ... sounds from different instruments or voices would reach the audience in the seats at different times. It would be a mess.

A circle.
Different cells move at sightly different speeds, but due to their size, it is very slow.
An object can move in a circle at different speeds.
It can
