Calculate the work (in joules) required to pump all of the liquid out of a full tank. Assume a=6 m, b=12 m, liquid exits through the spout, c=3 m, and density of the liquid is 1000 kg/m3. (Use decimal notation. Give your answer to two decimal place.)

Explanation:

From the expression of workdone, we no that

Workdone= force * distance

also  

force=pressure *area

since pressure = density*height* gravity

we have

work done=pressure * area * distance

from the question, the workdone will be a dependent function on the height

hence we can write

to get the absolute workdone, we have to integrate both sides

Hence we have

hello, i am papaguy.

i have found an answer to your question but use it as information.

information: because weak acids/bases have low concentration of hydrogen ions, the addition of water has a large impact on the ph. 2. a difference in 1 unit is a 10x difference in concentration for example; a liquid with ph of 3 is 10x more acidic than a liquid with a ph of 4. therefore, a liquid with a ph of 3 is stronger.

best of luck!
