10r - 5r + 3r - 8r
Simplify the expression by combining like terms

The answer is 0

Step-by-step explanation:

0

Step-by-step explanation:

10r - 5r + 3r - 8r

all of these have the common term of r, therefore simple addition of the integers would get you the answer in terms of r

10-5+3-8=0

question is incomplete.

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
