A trader bought a TV set for birr 2000 and sold it at a loss of 11% what was the selling price? ​

Step-by-step explanation:

loss of 11%

2000*(1-0.11)

2000*(0.89)

1780 birr

you subtract the 0.11 from 1 because you don't want to know how much he lost but you want to know how much he sold it for

you could also multiply 2000 from 0.11 and then subtract that from 2000

you would get the same answer

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
