Physics Questions

Tensional forces normally cause normal faults.

We know that, solids have definite shapes and definite volumes, whereas liquids have definite volumes but indefinite shapes and coming to gases it has indefinite volumes and indefinite shapes.

Hence, only in solids, the forces of attraction limit the motion of particles.

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.

Land is considered as an important resource because it is useful in producing many things. For example, in agriculture, land is used for cultivating the crop, in industrial use, it is used for constructing factories and to make products that we use.

Cast iron is a group of iron-carbon alloys with a carbon content greater than 2% and is a brittle material.

Its usefulness derives from its relatively low melting temperature.
