Afuel oil tank is an upright cylinder, buried so that its circular top 12 feet beneath ground level. the tank has a radius of 6 feet and is 18 feet high, although the current oil level is only 13 feet deep. calculate the work required to pump all of the oil to the surface. oil weighs 50 lb/ft^3.

I end up with 625pi(27^2-14^2)

=635pi(504)

=315000pi lb-ft

for a it would be 24 children.

for b i don't understand the question. is it saying for each individual person they pick 5 reds to 7 greens or is it the whole group. clarify and i hope this can you.

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
