Application of a forward bias to a $p-n$ junction

A $1\, kg$ stone at the end of $1\, m$ long string is whirled in a vertical circle at constant speed of $4\, m / s$. The tension in the string is $6\, N$, when the stone at $\left(g=10\, m / s ^{2}\right)$

The core of any transformer is laminated so as to

At a certain temperature, the first order rate constant, $k_{1}$ is found to be smaller than the second order rate constant, $k_{2}$. If the energy of activation, $E_{1}$ of the first order reaction is greater than energy of activation, $E_{2}$ of the second order reaction then with increase in temperature

The Brownian motion is due to

For a first-order reaction $A \rightarrow B$ the plot of $\log \left\{[A]_{t} / 1 M \right\}$ versus $t$ is linear with a

$\left[ CoCl _{2}\left( NH _{3}\right)_{4}\right]^{+}+ Cl ^{-} \longrightarrow \left[ CoCl _{3}\left( NH _{3}\right)_{3}\right]+ NH _{3}$ In the reaction only one isomer of complex product is obtained. The initial complex is

Consider the sequence of oxides : $Na _{2} O , SiO _{2}$, $P _{4} O _{10}$. Which factor decreases from $Na _{2} O$ to $SiO _{2}$ and also from $SiO _{2}$ to $P _{4} O _{10}$ ?

Which element belongs to $4n$ series?

$0.037\, g$ of an alcohol, $R$-OH was added to $C _{2} H _{5} MgI$ and the gas evolved measured $11.2\, cc$ at STP. The molecular mass of $R- OH$ will be
