Physics Questions

Land breezes are more common during winter and fall season. It occurs as it becomes night, the air on the land colls fast and air on the water surface are warmth than that and begin to rise.

Gravitational force is the force that binds everything at the surface of the earth. Gravitational force is maximum at Poles.

On the basis of magnetic properties, substances are classified into three groups namely diamagnetic, paramagnetic and ferromagnetic.

As solids diffuse and reorder very slowly under ambient conditions, the net, directionally dependent (anisotropic) magnetic moment can persist. Conversely, liquids and gases freely tumble and reorder: water rearranges every few pico seconds (10^12 times per second).

Hence liquids and gases can never show ferromagnetic properties.
