PLSSS HELP I GIVE BRAINIEST

A.

Step-by-step explanation:

correct answer is

if to compare the values of the y, (0;100), (1;91), (2;82.81), (3; 75.3571), then

75.3571/82.81=82.81/91=91/100=0.91, it means the next value is decreased at 9%.

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

one set of data has more variation than the other. hope this !
