Consider the standard equation for force, F = ma. In a centripetal system, the acceleration a is given by a = v^2/r. Plugging this in to the equation for force yields F = mv^2/r; hence to calculate centri...
EM waves invariantly travel at the speed of light, and can do so in a vacuum. They transfer energy from their source to the absorber. Some kinds of EM waves can be reflected and refracted. The spectrum of...
F = 10NA = 1x10^-6 m^2Therefore, Stress = 10 MPaStrain = Stress / E = 10 / 200 x10^3 = 5x10^-5 delta L = strain x length = 5x10^-4 cm = 5 micrometers
At the centre of the atom, is the nucleus. This is made up of protons and neutrons. Protons are positively charged, with a relative charge of +1. Whilst neutrons are neutral (relative charge = 0).Surround...
This problem should be split into two parts, the time it takes the ball to reach its maximum point, and the time it takes it to fall to the ground from the maximum point.part 1) We can calculate the balls...
