you should use brackets to obtain the proper order of operation, f '(x) = (2- lnx)/(2x^(3/2)) why don't we do part b) first, then 2 - lnx = 0 lnx = 2 , by definition lnx = 2 <----> e^2 = x so e^2 = x = appr. 7.39 so when x=e^2 we have a max/min value of the function f(e^...

A quantity of an ideal gas is compressed to half" its initial volume. The process may be adiabatic, isothermal or isobaric. Rank those three processes in order of the work required of an external agent, least to greatest. doesn't adiabatic mean no work, so it would be the ...

If you tried to copy and paste, it obviously didn't work. You'll need to type your question(s) in by hand. I've also heard (but not tried) that if you copy and paste into Notepad and then into Jiskha, that might work.

physics - power(1)
Have you learned that Work = Force x distance? Have you learned that Power = Work/Time ? Put them both together for the answer. The force is the weight, which M g. These are things you should know by now.
