Iwill give which of the following is a rational number? square root of 2, square root of 3, square root of 4, or square root of 5

The answer is the square root of 4.

2 * 2 = 4

2 is a rational number; therefore, the square root of 4 is a rational number.

Square root of 4

Step-by-step explanation:

First we need to find the square root of each of these numbers

Square root of 2: 1.41421356 and so on

Square root of 3: 1.73205080 and so on

Square root of 4: 2 this is the only rational number

Square root of 5: 2.2360679 and so on

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

answer: -0.5 would be the most likley outcome
