A reasonable estimate for the height of an ordinary adult male is
A) 50 cm.
B) 70 cm.
C) 200 cm.
D) 300 cm.
Question 2
Compared with the efficiency of a typical steam-electric generating plant, the efficiency of a typical hydro-electric generating plant is
A) smaller because a steam-electric converts thermal energy into non-thermal forms and the second law of thermodynamics implies that this is a highly efficient process.
B) smaller, because only a small amount of the energy in the water behind a dam can be converted into electricity.
C) greater because a hydro-electric plant uses the sun as its source of energy, rather than hard-to-obtain fossil fuels.
D) about the same, because both are heat engines and so both have the large inefficiency implied by the second law of thermodynamics.
E) greater because a hydro-electric plant is not a heat engine and so it does not have the large inefficiency implied by the second law of thermodynamics.
