As the clay ball falls and hits the floor, does the total amount of energy in the system (the clay ball and the floor) increase, decrease, or stay the same? Why? The total amount of energy in the system increases because the clay ball and the floor are warmer, and therefore, have more energy.

The total amount of energy in the system decreases. Although the energy of the clay ball and the floor increases as they get warmer, the energy of the clay ball decreases by an even greater amount as it moves closer to the ground.

The total amount of energy in the system stays the same because the decrease in energy due to the clay ball moving closer to the ground is equal to the increase in energy due to the clay ball and floor getting warmer.

The total amount of energy in the system stays the same. Even though the clay ball and the floor are warmer, being warmer is not associated with the amount of energy an object has.

Ms. w, a 21-year-old woman, came into a clinic after suffering a deep laceration on her foot while walking barefoot around her yard. the wound was cleaned, sutured, and bandaged, and she was released to return home after receiving tetanus antitoxoid. within 72 hours, the wound area was red and swollen, the suture line was dark in color, and it was accompanied by severe throbbing pain. ms. w had a high fever, her heart felt like it was racing, and she was finding it hard to concentraten even on simple tasks. she returned to the clinic and was immediately taken to the hospital. following lab tests, a diagnosis of acute necrotizing fasciitis was made. discussion questions 1. explain why ms. w. received a tetanus antitoxoid before leaving the hospital. (see chapters 3 and 4, infection and passive immunity.) 2. explain how acute necrotizing fasciitis developed in this case and the pathophysiology involved. (see acute necrotizing fasciitis.) 3. what is the potential outcome for ms. w if antibiotic drugs do not reduce the infection quickly?
