1. Graph the motion of the cheetah. It was standing near a tree then started running at a very fast speed 35 meters in 5 minutes. It stopped for 6 minutes trying to look further for his prey. Then
he started running for 15 meters in the same direction for 10 minutes. Then the cheetah
stopped for 4 minutes and went back to 35 meters towards the tree where he started in 5
minutes.

Under conditions for which the same room temperature is maintained by a heating or cooling system, it is not uncommon for a person to feel chilled in the winter but comfortable in the summer. provide a plausible explanation for this situation (with supporting calculations) by considering a room whose air temperature is maintained at 20â°c throughout the year, while the walls of the room are nominally at 27â°c and 14â°c in the summer and winter, respectively. the exposed surface of a person in the room may be assumed to be at a temperature of 32â°c throughout the year and to have an emissivity of 0.90. the coefficient associated with heat transfer by natural convection between the person and the room air is approximately 2 w/m2 â‹…â‹… k. what is the ratio of the thermal resistance due to convection to the thermal resistance due to radiation in the summer? what is the ratio of thermal resistances in the winter
