The well know mineral flourite is chemically calcium fluoride. It is a well known fact that in one unit cell of this mineral, there are four Ca^(2+) ions and eight F^(-) ions and Ca^(2+) ions are arranged in f.c.c. lattice. The F^(-) ions fill all the tetrahedral holes in the face centred cubic lattice of Ca^(2+) ions. The edge length of the unit cell is 5.46xx10^(-8) cm. The density of the solid is 3.18"g cm"^(-3) . Use this information to calculate Avogadro's number (Molar mass of CaF_(2)=78.0"g mol"^(-1) )

Under the action of a constant voltage U , a capacitor of capacitance C =10^(-11) F included in the circuit shown in Fig. 113 is charged to q_(1) = 10^(-9) C . The inductance of the coil, is L = 10^(-5) H , and the resistance of the resistor is R = 100 Omega . Determine the amplitude q_(0) of steadystate oscillations of the charge on the capacitor at resonance if the amplitude of the external sinusoidal voltage is U_(0) = U .
