Class 12th

When capacitor is removed

tan 45° = $\frac{X_L}{X_R}\Rightarrow \omega L=R$

When inductor is removed.

$tan45°=\frac{X_C}{X_R}\Rightarrow \frac{1}{\omega C}=R$

$i_0=\frac{V_0}{Z}=\frac{V_0}{\sqrt[]{R^2+{\left(\omega L-\frac{1}{\omega C}\right)}^2}}=\frac{V_0}{R}=\frac{220}{110}=2A$

Fermi level of p-type semiconductors will go downward

Stopping potential defined in terms of wavelength as :

$eV=\frac{hc}{\lambda }-?\Rightarrow 0.710eV=\frac{hc}{491}-?\Rightarrow 1.43eV=\frac{hc}{\lambda }-?$

Using above two equation we can calculate :

$\lambda =382nm$

Using truth table of logic gates

$Y=\overline{\left(A\overline{B}\right)+\left(\overline{A}B\right)}=\overline{\left(\left(A\overline{B}\right)\right)}\overline{\left(\left(\overline{A}B\right)\right)}$

$Y=\left(\overline{A}+\overline{B}\right)\left(\overline{A}+\overline{B}\right)=\left(\overline{A}+B\right)\left(A+\overline{B}\right)=AB+\overline{A}\overline{B}$

$A_2{B}_3?2A^{+3}+3B^{-2}$

1-α        2α        3α

$\therefore i=1+4\alpha =1+4*0.6=1+2.4=3.4$

$\Delta T_b=i{k}_{b}m=3.4*0.52*1=1.768\approx 1.77K$

$T_b=374.77K\approx 375K.$         

$logK=logA-\frac{Ea}{2.303RT}$

$Slope=\frac{Ea}{2.303R}=-10,000K$  

$\frac{Ea}{2.303R}=10^4$            

$log\left(10^{-5}\right)=logA-10^4*\frac{1}{500}$   (at 500 K temperature)

$\therefore T=\frac{10^4}{19}K=\frac{100}{19}*10^{2}K=5.2631*10^{2}K=526.31K\approx 526K$

When two or more individual charges are present in a system, the total charge will be an algebraic sum of all individual charges and not the vector sum. Therefore, an electric charge is considered as a scalar quantity.

This is an interesting question! Even though a proton has a positive charge, the net positive charge in a conducting material is always due to the removal of free electrons. 

This happens due to the availability of only free electrons in all conductors. Since protons are present in the nucleus, they can not roam freely in the conductor, as electrons travel freely in the conductor due to their presence in the outer shell.
