You and a friend both work two different jobs. the system of linear equations represents the total earnings for x hours worked at the first job and y hours worked at the second job. your friend earns twice as much as you. one week, both of you work 4 hours at the first job. how many hours do you and your friend work at the second job? both of you work the same number of hours at the second job. compare the number of hours each of you works at the first job?

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
