The base of a rectangular tank measures 50 cm by 40 cm. What will the height of the water level be when it contains 9 liters of water (1 liter = 1000 cm3).

height = 4.5 cm

Step-by-step explanation:

9 liters = 9000 cm^3

(50x40xH) = 9000

H = 4.5 cm

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
