Rock 3, because it has the most mass while still moving at the same speed, it is kinetic because there is movement and energy being used
Solution :
Energy of photon, E = 6.7 eV
E =
joule
Kinetic energy, 


Kinetic energy at high speeds


r - 1 = 7130
r = 7130 + 1
r = 7131


![$v^2=C^2\left[1-\left(\frac{1}{7131}\right)^2\right]$](https://tex.z-dn.net/?f=%24v%5E2%3DC%5E2%5Cleft%5B1-%5Cleft%28%5Cfrac%7B1%7D%7B7131%7D%5Cright%29%5E2%5Cright%5D%24)

Δ = 1 - 0.99999999017
= 0.00000000933
Relative mass, 

kg
I think it’s cause no change i think
Answer:
Frequency
Explanation:
Each half wavelength has a point of largest amplitude (aka a node). Depending on the wavelength each node oscillates at a certain rate of swings per unit of time. The latter is referred to as frequency and measure in Hertz [Hz].
