A person does not apply sunscreen and has 0.43 m2m2 of skin exposed to the sun for 1.00 hh. Calculate the total energy (in joules) absorbed by the skin. Assume there are 3.066×1021 photons/(m2⋅s)photons/(m2⋅s) (photons per square meter-second). Assume an average wavelength of 320 nmnm to calculate the energy of a UV photon. Assume that half of the photons that strike the skin are reflected. Express the energy in joules to three significant figures
