Can someone help me with this

9

Step-by-step explanation:

If the x:y ratio is 6:72, then first you have to find how to get 72 from 6. 12*6 is 72

The formula now is y = 12x, then you reverse that to find y. y/12 = x

So do 108/12 = 9

9 is x

step-by-step explanation:

we can use this expression to calculate the energy gain as a particle moves with a field or the energy loss as it moves against it. (note that it is also used to define the electron-volt, a unit of energy equal to that gained by an electron as it falls through a pd of 1 v, i.e. w = 1 ev = 1.6 10-19 c 1 v = 1.6 10-19j).in fact this expression is really nothing more than the statement that potential is the potential energy per unit charge. in this case, v= w/qis simply stating that the change in potential energy(or work done) per unit charge is equal to the change in potential (or potential difference), v.student questions: uniform electric fields2electron beamcathode+5 kvanode0 v
