Atwo dimensional ideal bose gas: n bosons of spin oland mass : / moving in a region of are. a with. n,a-→o , and finite concentration nan/a.ヤ the gas is in equilibrium at temperature t. (a) whát is the energy density of single-particle states? (b) calculate u as à function of temperature t, (hint: the relevant integral can be simplified with substitution x-exp(-e/kt) (ans. 2makt

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

Arefrigerator uses r-134a as the working fluid and operates on the ideal vapor-compression refrigeration cycle except for the compression process. the refrigerant enters the evaporator at 120 kpa with a quality of 34 percent and leaves the compressor at 70°c. if the compressor consumes 450 w of power, determine (a) the mass flow rate of the refrigerant, (b) the condenser pressure, and (c) the cop of the refrigerator. (0.00644 kg/s, 800 kpa, 2.03)

What would people living along the coast in south florida do if there was a hurricane warning? move to locations away from the water flock along coasts to watch the natural phenomenon buy instruments to predict the exact location of the hurricane measure water levels to know the exact time of the hurricane
