First thing first, we need to fully understand what we are asked and what topic we are being tested on. From this question, we can see that we are involved in electric fields, sicn...
To start, the equation to use can be identified as the capactior discharge equation V(t) = Vmaxe-t/RC. From here, we can see that this equation can be solved to give capacitance, and...
F=Eq= 5x10^2 x 1.6x10^-19 = 8x10^-17 N
Kinetic energy theory: deltaEc= Fxd =1/2mv^2
thus v= squareroot(2xFxd/m)
v(proton) = squareroot(2x8x10^-17x1x10^-2/9.1x10^-31)=1.3x 10^6 m/s
The Doppler Shift describes a change in frequency of a wave that an observer sees when moving relative to the source of the waves.
A good example of the Doppler Shift is the change in pitch (how hi...
According to the particle theory of light, hf=φ+KEmax, so along with the minimum amount of energy required, there is a minimum frequency as well, φ= hfo. Thus, the incident photon must have a f...
