Each time Laurie dove 5 feet deeper she would stop and clear her ears. After she had checked her instruments 3 times she was at her maximum depth of 60 feet. Which expression best represents Laurie's Maximum depth. (4)(-5)(3) or (-4)(-5)(-3) or (-5)(20)(3) or (-5)(-20)(-3)

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

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
