Are all atoms the same in an element?

Are all atoms the same in an element? Yes, all things are made of atoms, and all atoms are made of the same three basic particles – protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. What property […]

How many alternate universes are there?

How many alternate universes are there? One obvious question that arises, then, is exactly how many of these parallel universes might there be.

Two characteristics define brightness: luminosity and magnitude. Color. A star’s color depends on its surface temperature. Surface Temperature. Size. Mass. What is the most important characteristic of a star […]

What can cause a population to be in a uniform distribution?

What can cause a population to be in a uniform distribution? Uniform patterns of dispersion are generally a result of interactions between individuals like competition and territoriality. Clumped patterns usually occur when resources are concentrated in small areas within a larger habitat or because of individuals forming social groups. What are the factors for population […]

What is the direction of average velocity?

What is the direction of average velocity? Average velocity is the ratio of total displacement to total time. Its direction is the same as the direction of the moving object. Even if the object is slowing down, and the magnitude of the velocity is decreasing, its direction would be still the same as the direction […]
