Hace 9 horas · Air is thin enough that in the Earth's atmosphere radio waves travel very close to the speed of light. The wavelength is the distance from one peak (crest) of the wave's electric field to the next, and is inversely proportional to the frequency of the wave. The relation of frequency and wavelength in a radio wave traveling in vacuum or air is.

Hace 9 horas · Newton's laws of motion are three physical laws that describe the relationship between the motion of an object and the forces acting on it. These laws, which provide the basis for Newtonian mechanics, can be paraphrased as follows: A body remains at rest, or in motion at a constant speed in a straight line, except insofar as it is acted upon by ...

Hace 9 horas · For blue giants (see this ), the masses are in the range 10 -300 M Sun and the radii vary in the range 10 -100 R E as the table of the Wikipedia article shows. The amount of ordinary baryons produced would be in the range 10 2 -10 4 M E at most and considerably smaller than M Sun ∼ 10 6 M E .
