The universal wave equation states that v = fë, therefore wavelength is directly related to the speed of the wave. That means that if the frequency is increased, the speed is also increased and vice versa, as long as frequency is kept constant.

My question is 'what does the area under the curve represent?' it's a Maxwell-Boltzmann curve. My first idea was the number of particles but that's just what the y axis says and surely that wouldn't just mean under the curve. My second idea was to write tha...

, block A (mass 2.04)kg rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B (mass 3.00 )kg. The coefficient of kinetic friction between block A and the tabletop is 0.215. After the blocks are released from re...
