A) 1/4a + 1/2b

Step-by-step explanation:

3/4a +1/2b - 1/2a

3/4a -1/2 a     + 1/2 b

We need a common denominator for the a terms which is 4

3/4a - 1/2*2/2 a  + 1/2 b

3/4a -2/4a     + 1/2 b

1/4a + 1/2 b

x=half

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
