At 10: 30 am, detectives discover a dead body in a room and measure its temperature at 27°c. one hour later, the body's temperature had dropped to 24.8°c. determine the time of death (when the body temperature was a normal 37°c), assuming that the temperature in the room was held constant at 22°c. (round your answer to two decimal places.)

: the time of death was hours before 10: 30 am.

Aplayground slide is 8.80 ft long and makes an angle of 25.0° with the horizontal. a 63.0-kg child, initially at the top, slides all the way down to the bottom of the slide. (a) choosing the bottom of the slide as the reference configuration, what is the system's potential energy when the child is at the top and at the bottom of the slide? what is the change in potential energy as the child slides from the top to the bottom of the slide? (include the sign of the value in your answer.)
