Stress = Force/Area and cross sectional area of a cyclinder = pi.r2As diameter = 10.0cm=0.1m r=0.05m so area = 3.14*0.052 = 0.00785m2As the force is 50.0N the...
E=hf, so as you increase the frequency of light, the energy of each photon hitting the metal surface is greater. Thus the electrons liberated from the surface of the metal have a greater maximum kinetic e...
A stationary wave is a wave formed by the superposition of two progressive waves. These waves must have equal amplitude frequency and speed. They must also be travelling in opposite directions. When a wav...
If we break down the velocity vector into its x and y components, then the point at which the ball would be moving horizontally is the point where the y velocity is zero. The y velocity decreases initiall...
First recall the suvat equation: v^2=u^2+2as.It is always handy to draw a diagram in physics to illustrate the problem. Next, using u=5, a=10, s = 10, solve for v in the suvat equation, arrivi...
