Be sure to answer all parts. A woman expends 93 kJ of energy in walking a kilometer. The energy is supplied by the metabolic breakdown of food intake and has a 35 percent efficiency. If the woman drives a car over the same distance, how much energy is used if the car gets 8.8 km per liter of gasoline (approximately 20 mi/gal)? The density of gasoline is 0.71 g/mL, and its enthalpy of combustion is 49 kJ/g. Enter your answer...

Be sure to answer all parts. What is the energy (in J) of one photon of 639 nm wavelength light? Enter your answer in scientific notation. Cx10J Enter your answer in the provided box. The human eye is a complex sensing device for visible light. The optic nerve needs a minimum of 2.0 x 10'7 J of energy to trigger a series of impulses that eventually reach the brain. How many photons of blue light (475 nm) are needed?

Be sure to answer all parts. Mass and energy are alternate forms of a single entity called mass-energy. The relationship between these two physical quantities is described by Einstein's equation, E = mc², where Els energy, mis mass, and c is the speed of light (3.00 x 108 m/s). In a combustion experiment, it was found that 12.096 g of hydrogen molecules combined with 96.000 g of oxygen molecules to form water and released 1.715 10 kJ of heat. Calculate...

Be sure to answer all parts. A person inhales air richer in O2 and exhales air richer in CO2 and water vapor. During each hour of sleep, a person exhales a total of about 300. L of this CO2−enriched and H2O-enriched air. (a) If the partial pressures of CO2 and H2O in exhaled air are each 28.3 torr at 37.0°C, calculate the masses of CO2 and of H2O exhaled in 1 h of sleep. -g CO2 -g H2O (b) How...
