Aresistor with r1=25.0 ohm is connected to a battery that has internal resistance and electrical energy is dissipated by r1 at rate of 36.0 w . if a second resistor with r2= 15.0 ohm is connected in series with r1 , what is total rate at which electrical energy is dissipated by the two resistors

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).
