Base of rectangular tank is 3.2m by 2.8m. Height=2.4m. It contains water to a depth of 1.8m. Calculate surface area inside tank that is not in contact with water.​

answer: the answer is 35%

the answer is a

step-by-step explanation:

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

the correct answers i think are b. and d.

give me brainliest if it is correct!
