The common Indian bullfrog is:

The conjugate base of $HBr$ is:

$\sqrt[3]{61 - 46\sqrt{5}} = $

What is the output $Y$ in the following circuit,when all the three inputs $A, B, C$ are first $0$ and then $1$?

$A$ charge $Q$ is divided into two charges $q$ and $Q-q$. The value of $q$ such that the force between them is maximum,is

In the circuit shown in the figure,the $AC$ source gives a voltage $V = 20 \cos(2000t)$. Neglecting source resistance,the voltmeter and ammeter readings will be
