WebNothing can travel faster than 300,000 kilometers per second (186,000 miles per second). Only massless particles, including photons, which make up light, can travel at that speed. It's impossible to accelerate any material object up to the speed of light because it would take an infinite amount of energy to do so. Thus an accelerating universe took a longer time to expand from 2/3 to 1 times its present size, compared to a non-accelerating universe with constant ˙ and the same present-day value of the Hubble constant. Meer weergeven Observations show that the expansion of the universe is accelerating, such that the velocity at which a distant galaxy recedes from the observer is continuously increasing with time.

WebSo each electron gains kinetic energy equal to the amount of energy transferred electrically. The electron starts from rest (near enough) so the kinetic energy gained is given by ½ mv 2 where m is its mass and v is its speed. So we can say that: ½ mv 2 = eV. The mass of the electron is m = 9 × 10-31 kg. The electronic charge is e = 1.6 × 10 ...
