Two friends are playing a version of proton golf where the hole is marked by a single proton. the first friend reads his meter, and declares he has a field strength of 24.0 n/c. the second friend looks at her meter and realizes she is three times as far away. what field strength does the second friend's meter read?

Determine the amount of work done when a crane lifts a 100-n block form 2m above the ground to 6m above the ground

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
