You and Tim, who is larger than you, are outside with a wagon. Tim (the bigger person) gets in the wagon and you (the smaller one) pull it. As you pull it, you accelerate until you reach a comfortable velocity. Then you stop and switch places with Tim. Tim now pulls you in the wagon, accelerating from a stop to a comfortable velocity. Now, Tim may be bigger than you, but you have been working out and are just as strong as Tim, so the force that Tim uses to pull the wagon is the same force that you used. You both pull with the exact same amount of force. Who was riding in the wagon when it had the greatest acceleration during startup? (2 points) Why? Use Newton’s second law to explain. (3 points)

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
