Which is a true statement regarding the law of mass balance? a. solids, gases, and liquids have their own specific equations for the law of mass balance. b. when the body converts a nutrient to another substance, there is no effect on mass balance. c. the law of mass balance applies to the input/output relationship of solids, liquids, and gases. d. the law of mass balance states that substances in the body are kept at constant levels because the human body is a closed system.

How are calculation for velocity and speed different

Some material consisting of a collection of microscopic objects is kept at a high temperature. a photon detector capable of detecting photon energies from infrared through ultraviolet observes photons emitted with energies of 0.3 ev, 0.5 ev, 0.8 ev, 2.0ev, 2.5ev, and 2.8ev. these are the only photon energies observed. (a) draw and label a possible energy-level diagram for one of the microscopic objects, which has four bound states. on the diagram, indicate the transitions corresponding to the emitted photons. explain briefly. (b) would a spring–mass model be a good model for these microscopic objects? why or why not? (c) the material is now cooled down to a very low temperature, and the photon detector stops detecting photon emissions. next, a beam of light with a continuous range of energies from infrared through ultraviolet shines on the material, and the photon detector observes the beam of light after it passes through the material. what photon energies in this beam of light are observed to be significantly reduced in intensity (“dark absorption lines”)? explain briefly.
