If a person is standing near a building that explodes, which of the following
injuries would he or she MOST likely experience as a result of the pressure wave?
A. Eardrum rupture
B. Fractured bones
C. Impaled objects
D. Severe burns - ANSWER -A. eardrum rupture
By what mechanism is a person injured when he or she falls from a significant
height?
A. Kinetic energy is converted to potential energy; the potential energy is then
converted into the work of bringing the body to a stop.
B. Potential energy is converted to kinetic energy; the kinetic energy is then
converted into the work of bringing the body to a stop.

converted into kinetic energy upon impact. - ANSWER -B. potential energy is
converted to kinetic energy; the kinetic energy is then converted into the work of
bringing the body to a stop
