Answer questions 5 and 7 and the problem next to 7 u, if there gets 2 answers if u ask i will give u the brainlest answer!

#5 (5^2+3^2) x (81+9) /10

(25+9) x 90/10

34x90/10

3060/10 = 306

7.  2 x 3 x 6 = 36 cubic feet

5 the 5 in 3.5 is 10 times the value as in 2.75 ( 0.05 x 10 = 0.5)

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
