Aproton moves in an electric field from point x to point y. if the potential difference
between the two points is 400 v, what is the speed of the proton when it passes through point y? the
speed of the proton at point x is 4.5 x 10^5 m/s. (charge on a proton = 1.6 x 10^-19 c mass of proton
= 1.67 x 10^-27kg)

This chart shows characteristics of three different types of waves. which statement is best supported by the information in the chart? wave x and wave y are mechanical waves, and wave z is an electromagnetic wave. wave x and wave y are electromagnetic waves, and wave z is a mechanical wave. wave x and wave z are electromagnetic waves, and wave y is a mechanical wave. wave x and wave z are mechanical waves, and wave y is an electromagnetic wave.
