Me man idk how to do this i tried but this ain't working

just going to explain the first one

Step-by-step explanation:

so, you can tell by the square in the corner that its a 90 degree angle.

take 56 and subtract from 90 and you should get 34

after that its straight forward from there

just do 3+7= 10

subtract 10 that from 34

and what you have left should be x.

x=24

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
