The half-life of a radioactive substance is $30\text{minutes}$. The time (in minutes) taken between $40\%$ decay and $85\%$ decay of the same radioactive substance is:

For CE transistor amplifier, the audio signal voltage across the collector resistance of $2\text{k}\Omega$ is $4\text{V}$. If the current amplification factor of the transistor is $100$ and the base resistance is $1\text{k}\Omega$, then the input signal voltage is:

The given circuit has two ideal diodes connected as shown in the figure below. The current flowing through the resistance $R_1$ will be:

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