(PLEASE HELP I'LL MARK BRAINLIEST) Breanna connected a wire coil to a lightbulb to demonstrate that a moving magnet can cause a current to flow in a wire. Then she moved a bar magnet first toward and then a way from the wire coil. However, she could not make the lightbulb up. Which factor could explain this outcome? A. She moved the bar magnet toward the wire coil too quickly.

B. She did not connect the wire coil in the correct direction.

C. She moved the bar magnet below the wire coil instead of above the coil.

D. She did not move the bar magnet through the wire coil.

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
