(Numerator is the number on the top, denominator is the number on the bottom: )

Decimal ⇒ Percent

Multiply by 100 (OR Move the decimal 2 places to the right.)

Decimal ⇒ Fraction

Say the decimal out-loud (correctly). Write the fraction as it sounds, then simplify if needed.

Percent ⇒ Decimal

Divide by 100 (OR Move the decimal 2 places to the left)

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
