two iron balls of different mass are heated to 100°c and dropped in water. if the same amount of heat is lost by the two balls to water, what can be said about the final temperatures of the two balls? (heat lost = mcpδt, where m = mass of the object, cp = specific heat capacity of the material, and δt = change in temperature).
a) both balls will have the same temperature as the heat lost by both balls is the same.
b) both balls will have the same temperature as the specific heat capacities of both balls are the same.
c) the lighter ball will have a higher temperature because the change of temperature is directly proportional to mass.
d) the heavier ball will have a higher temperature because the change of temperature is inversely proportional to mass.

Aproduction line at v. j. sugumaran's machine shop has three stations. the first station can process a unit in 7 minutes. the second station has two identical machines, each of which can process a unit in 16 minutes (each unit only needs to be processed on one of the two machines). the third station can process a unit in 10 minutes. ▼ is the bottleneck station, with a bottleneck time of nothing minutes per unit (enter your response as a whole number).
