One-tenth kg of a gas in a piston-cylinder assembly undergoes a Carnot power cycle for which the isothermal expansion occurs at 800K. The change in specific entropy of the gas during the isothermal compression, which occurs at 400K, is -25 kJ/kg-K. Determinea)The net work developed per cycle, in kJ;( 1000 kJ)b)The thermal efficiency

True or false graphs must include scales that increase by the same amount

Why does karst topography exist in some geographic location? a. few climates have enough oxygen b. most regions have rock layers other than limestone c. in most regions, the soil is too thin d. the water is too acidic enough in most places

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
