Gamma rays are emanations that have neither mass nor charge.

The first talkie film in India was Ardeshir Irani released Alam Ara, on 14 March 1931.

Galvanised iron sheets have a coating of zinc.

In the given options, a high-fat diet is the only factor that contributes to hypertension.

Let the two different rates of interests be r1 and r2 respectively.

From the given data,

$$\begin{gathered} 2600 x 4 x r1 - r2100 = 402.80 \\ r1 - r2 = 402.80104 = 3.87 \end{gathered}$$

Hence, the difference in the interest rates = 3.87

S8 is an elemental form of sufur. In elemental form it can't be reduced or oxidized. Hence, it oxidation number is zero and thus sulfur is zerovalent here.

Electronegativity, is a chemical property that describes the tendency of an atom to attract a shared pair of electrons (or electron density) towards itself.

Sound waves cannot travel through a Vacuum.

A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.
