For pure H2 at 3 atm, estimate the thermodynamic potential difference between pure oxygen and air at 3 Atm. For reformate, H2 is about 25%, estimate the decrease of thermodynamic potential relative to pure H2. If we are to develop a fuel cell under 700 bar with the H2 and air, please estimate the thermodynamic voltage; and comment on the value.

To protect all four receptacles on a branch circuit that surrounds a swimming pool, you would install which of the following configurations? a. gfci feed-through receptacle at the end of the load's circuit b. gfci-terminated receptacle at the beginning of the load's circuit c. gfci feed-through receptacle at the beginning of the load's circuit and the other receptacles connected to the load side of that receptacle d. gfci-terminated receptacle at each end of the load's circuit

The car hoist allows the car to be driven onto the platform, after which the rear wheels are raised. if the loading from both rear wheels is 1380 lb, determine the force in the hydraulic cylinder ab. neglect the weight of the platform itself. member bcd is a right-angle bell crank pinned to the ramp at c. the force is positive if in tension, negative if in compression.

Aphysical change is a change in the size, shape,, or stafe of matter true or false
