What percent is 55 out of 90.

roughly 61.1%

Step-by-step explanation:

if you divide both numbers, 55 over 99 you'll get 0.61 repeated. then you'll multiply by 100 to get 61.1 repeated

just take the area of the square and then the area of the circle then subtract the circle area from the squares area

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
