a=5 in

Step-by-step explanation:

surface area A=6a^2 ( it is a cube all edges are equal)

a=√A/6=√150/6=√25=5

The length of the side of one side of a square face is 5 in, which agrees with the second answer in the list of options.

Step-by-step explanation:

Recall that a cube has 6 equal faces, therefore, the area of each face must be :

Then, if the area of each square face is 25 , then, recalling that the area of a square of side "b" is:

then:

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
