Two color coding schemes exist to guide applicators when selecting. nozzles for pesticide applications. The color schemes are designed to. help applicators achieve accurate, effective crop protection. It may be. confusing, but the color schemes represent flow rate and droplet. size and are independent of one another.
If E = mc^2, and light = E, then light = mc^2. Therefore light is matter. Given, as Claude Bile stated (post #4), âE = mc^2 is the equivalence of mass and energy, not matter and energyâ, I guess they are saying that because light has relativistic mass it is matter.
Over 13 billion years since the Big Bang, hydrogen and helium still make up most of the visible matter in the universe. Nearly 10,000 galaxies appear in this Hubble Ultra Deep Field image.
