A, with a charge of−5.0μC, is located 3.0cm to the left of sphereB, with a charge of +3.0μC. a. What is the force of sphereB on sphereA? b. A third sphere, C, with a +2.0 μC charge, is added 5.0cm directly beneathA. What is the new net force on sphereA : Convert μCto C . (x10 -6)Convert cm to m . (x 10-2)

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

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

Anybody wanna ? (picture included? )
