The difference of a square of a number and 12 is equal to four times that number

Hello there! Your answer is 4.

Step-by-step explanation:

N^2 - 12 = N * 4.

4^2 - 12 = 4 * 4.

16 - 12 = 16.

4 = 16.

The number on the right is 4 times of the number on the left.

Hope this helped!

76%

step-by-step explanation:

24% are dogs and the remaining is 76% because 100-24=76

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
