the pressure thing is a law- look at pascal's vases. Pressure in a liquid is not affected of the base changes. - do you see A area in the formula pgh ;)

when the circuit is open its obvious that everything would be O bcuz no current no voltsage
i wrote the vaukle but realsied when i READ the othe part which said when the circuit is colsed i am like wait a minute whats for a) so yaaa:D

HEY CAN ANYONE PLEASE TELLL MEE IF THEY USED EFFICIENCY EQUATION TO FIND POWER OUTPUT?????????
efficiency = power output/power input * 100???
and did they get 54W or something like that??
and d fraction is 1/8????

i got first output = 54000 W and my fraction was 1\8 ..but how did you guys know tht 1\8 is surely correct??
