W wodospadzie o wysokości 50 m w czasie 12 min spada 900 m3 wody. Oblicz jaką moc można uzyskać z turbin wodnych napędzanych wodą tego wodospadu, zakładając że uda się wykożystać tylko 50% spadającej wody.

Two vectors are shown. which statement best compares the vectors? vector x has greater magnitude than vector y. vector y has greater magnitude than vector x. the vectors have the same displacement. the vectors have the same direction.

Agas contained within a piston-cylinder assembly undergoes three processes in series: process 12: compression with pv= constant from 1 bar and 1 liter to 4 bar. process 23: constant pressure expansion to 1 liter. process 31: constant volume calculate the pressure and volume at each state, and sketch the processes on a p-vdiagram labeled with pressure and volume values at each numbered stat
