Three liquids are at temperatures of 6 °C, 24°C, and 40°C, respectively. Equal masses of
the first two liquids are mixed, and the equilibrium temperature is 13°C. Equal masses of the second and third are then mixed, and the
equilibrium temperature is 36.6°C. Find the equilibrium temperature when equal masses of the first and third are mixed. Answer in units of °C.

The magnitude of the poynting vector of a planar electromagnetic wave has an average value of 0.939 w/m^2 . the wave is incident upon a rectangular area, 1.5 m by 2.0 m, at right angles. how much total electromagnetic energy falls on the area during 1.0 minute?

The average atmospheric pressure on earth is approximated as a function of altitude by the relation patm = 101.325 (1 − 0.02256z)5.256, where patm is the atmospheric pressure in kpa, and z is the altitude in km with z = 0 at sea level. determine the approximate atmospheric pressures at atlanta (z = 306 m), denver (z = 1610 m), mexico city (z = 2309 m), and the top of mount everest (z = 8848 m).
