Two capacitor of value 4 micro farad and 6 micro farad call connected in parallel is connected to a 30 micro farad in series of a 220volt power supply is connected across this arrangement 1) the equivalent capacitance of the circuit .

2) the voltage across 30micro farad

3) the charge on each capacitor​

Agas initially at p1 = 1 bar and occupying a volume of 0.5 liter is compressed within a piston–cylinder assembly to a final pressure p2 = 4 bar. (a) if the relationship between pressure and volume during the compression is pv = constant, determine the volume, in liters, at a pressure of 3 bar. (b) repeat for a linear pressure–volume relationship between the same end states. reference

30 points - when can a theory be modified if a new type of technology allows for new observations that raise new questions? a. immediately, while the questions about the theory are being asked b. after new hypotheses related to the theory are tested in experiments c. only after the new observations disprove all parts of the theory d. while scientists begin to think about how the theory could improve

Scientific models are based on current knowledge, which can limit their effectiveness when new discoveries are made.
