Can you help me pleaseee!​

Step-by-step explanation:

=0.4

because a objest cannot be wieghed negatively unless its lighter than air

-0.4

Step-by-step explanation:

Because 93.5g - 93.9g you could either flip the equation around or keep it the same and subtract and you would get 0.4 but add the - because yoyr subtracting sorry if im wrong but hope this helps <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

ratio is 2 : 9

the answer is three

13.5 : 3
