Calculate the maximum possible efficiency of a power plant that burns natural gas at a temperature of 600k, with low temperature surroundings at 300k. how much more efficient would the plant be if it were built in the arctic where the low temperature reservoir is at 250k? why don't we build all power plants in the arctic?

600-300=300 

300 divide by 600=0.5 

0.5x100= 50%

explanation:

as the height from which the ruler was dropped increased, the speed of the ruler at ryan's hand increased.

a) electrical > light, sound, and thermal< < < <

) the mechanical energy of the firefighter moving.< < < < a) electrical > light, sound, and thermal< < < <

c) both a and b.
