At a sale carnival, Encik Rosli chooses a T-shirt from a rack which displays tag as shown in Diagram 20. The original price of the T-shirt is RM85. When Encik Rosli scans the price tag of the shirt, the scanner shows that the price is RM57.80. Determine whether this percentage discount corresponds to the percentage discount displayed. Give a reason for your 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

hello i might . what do you need.

friend me

y∈r, 8> y≥0

hope i !

p.s the first bit only matters if you know what that means.

p.p.s brainliest would really

umm you say your want to . but you do know that this is the mathematics.
