Physics Questions

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.

Nuclear Force

A gamma ray or gamma radiation, is a penetrating electromagnetic radiation arising from the radioactive decay of atomic nuclei. It consists of the shortest wavelength electromagnetic waves and so imparts the highest photon energy.

Gamma rays are emanations that have neither mass nor charge.

The primary agent of contact metamorphism is heat or temperature.

Graphite is a good conductor of electricity as it contains free electrons to move through the structure of the graphite.

The viscosity of a fluid is a measure of its resistance to deformation at a given rate. For liquids, it corresponds to the informal concept of "thickness".

Here in the given options, syrup has the highest viscosity.
