If the concentration of ag+ is 0.0115 m, the concentration of h+ is 0.355 m, and the pressure of h2 is 1.00 atm, calculate the cell potential at 25.0°c. the standard reduction potentials are: $$ eo = 0.80 v $$ eo = 0.00 v

In a system, when potential energy decreases, then entropy also decreases. true false

Engines for propeller-driven aircraft are limited in their maximum rotational speed by the fact that the tip speed of the propeller must not approach the speed of sound in air (mach i). taking 6 ft as a typical diameter for a propeller of a light airplane and 1100 fils as the speed of sound, find the upper limit on the rpm (revolutions per minute) of the propeller shaft.

I’ve been stuck on this for a while
