you park in a garage 3 floors
below ground level. then you get in the
elevator and go up 12 floors. write an
addition expression to represent this
situation. then find the sum.

it's easy if you're 3 below ground level then it would be -3 and now you just add 12

Step-by-step explanation:

-3+12=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
