As CPH has mass, how massless photon is made of two or more CPH? Answer; The Photon carries energy and energy has mass. But the rest mass of photon is aero. No one can see phot
3 scenarios: You have an object such as a jar, and you submerge it under water to 50m depth. (Every 10m down increases pressure by 1 bar, thus the pressure is 5 bar). Scenario 1:
As a longitudinal wave moves through a medium, the particles of the medium: w) Vibrate in a path parallel to the path of the wave x) Vibrate in a path perpendicular to t
