The ball accelerates because of gravity.
Wave speed = frequency * wavelength
Wave speed = 4 * 25
Wave speed = 100 m/s
Breathe and now I’m just filling in more letters so it’ll go thru
It is defined by their wavelength. Different colors have different wavelengths. For example, radio waves have a really long wavelength, whereas gamma-rays have a very short wavelength.
Newton's first law of motion best illustrates the principle of inertia<span />
