If the cold junction of a thermocouple is kept at $0{}^{\circ }\text{C}$ and the hot junction is kept at $T{}^{\circ }\text{C}$, then the relation between neutral temperature ($T_n$) and temperature of inversion ($T_i$) is:

Nickel shows ferromagnetic property at room temperature. If the temperature is increased beyond Curie temperature, then it will show:

In radioactive decay process, the negatively charged emitted $\beta$ -particles are:

A small coin is resting on the bottom of a beaker filled with a liquid. A ray of light from the coin travels up to the surface of the liquid and moves along its surface. How fast is the light traveling in the liquid?

What is the value of inductance $L$ for which the current is a maximum in a series $LCR$ circuit with $C=10\mu \text{F}$ and $\omega =1000{\text{s}}^{-1}$?
