Using the standard potential values given below, decide which of the statements P,Q,R,S are correct? Choose the right answer from (a), (b), (c ) and (d). Fe^(2+) + 2e^(-) rightarrow Fe , E^(@) = -0.44V Cu^(2+) + 2e^(-) rightarrow Cu , E^(@) = +0.34V Ag^(+) + e^(-) rightarrow Ag , E^(@) = +0.80V (P) Copper can displace iron from FeSO_(4) solution (Q) Iron can displace copper from CuSO_(4) solution (S) Iron can displace silver from AgNO_(3) solution

A horizontal tube having cross sectional area A_(1)=10cm^(2) has a venturi connected to it having cross sectional area A_(2)=4 cm^(2) . A moanometer, having mercury as its liquid is connected to be has uniform cross section and it has a horizontal part of lenght L=10cm. When there is no flow in the tube the height of mercuty column in both vertical arms is H=12cm. calculate the minimum flow rate (in m^(3)//s ) of air through the tube if it is required that the entire amount of mercury move to one vertical arm of the manometer. Gives, density of Hg=13.6xx10^(3)kgm^(3) , density of air=1.2 kg m^(-3) .
