Two resistors have resistances r1= ( 24+- 0.5)ohm and r2 = (8 +-0.3)ohm . calculate the absolute error and the percentage relative error in calculating the combination of two resistances when they are in parallel.

Which one of the following research methods can show cause and effect

Which best describes the difference between internal and thermal energy?

On a mild saturday morning while people are working inside, the furnace keeps the temperature inside the building at 23degreesc. at noon the furnace is turned off, and the people go home. the temperature outside is a constant 16degreesc for the rest of the afternoon. if the time constant for the building is 3 hr, when will the temperature inside the building reach 18degreesc? if some windows are left open and the time constant drops to 2 hr, when will the temperature inside reach 18degreesc?
