6. Ben says to Jerry that the potential energy change of the Ben-Earth system as he climbs a ladder from the first rung to the fourth rung is smaller than the potential energy change of the same system as he
climbs from the second rung to the fifth rung because gravitational potential energy is proportional to
height and the height of the fifth rung is greater than the height of the fourth rung. In response, Jerry
draws a diagram with two ladders with one in the basement and one on the first floor. Construct Jerry's
diagram and annotate the diagram to support his evaluation of Ben's claim.

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

Anybody wanna ? (picture included? )

How is zig zagging a form of acceleration?
