During photosynthesis in a certain plant, eight photons of 670-nm wavelength can cause the following reaction: 6CO₂ + 6H₂O → C6H12O6 + 60₂- During respiration, when the plant metabolizes sugar, the reverse reaction releases 4.9 eV of energy per CO₂ molecule. Part A Determine the ratio of the energy released (respiration) to the energy absorbed (photosynthesis), a measure of photosynthetic efficiency.

A. The binding energy of Sodium is 2.28 eV. Calculate the number of photoelectrons ejected from a 1.00 mm? area of Sodium metal by 500-nm electromagnetic radiation having an intensity of 1.30 kW/m?. What power is carried away by the electrons? B. A 60-kg person accidentally ingests a small source of alpha particles (RBE=15). The activity of the source is 0.04 Ci, the half-life of the source is 110 years, and each alpha particle emitted has an energy of 0.586 MeV. It takes 12 hours for the alpha source to pass through the person's digestive system and exit the body. i. How many alpha particles are absorbed by the person (assume that 100 percent of the alpha particles emitted by the source are absorbed by the person)? ii.
