Physics Questions

Pitot tube is used to measure stagnation pressure.

When you compress or stretch a spring, as soon as the stress is relieved, the spring attains its normal shape instantly. Its Elastic potential energy helps it do so. Generally, these elastic substances follow the Hooke’s law.

According to this Law, the force needed to change the shape of spring is proportional to the displacement of the spring. The displacement referred here is how far the spring is compressed or stretched from its normal shape. Mathematically, Hook’s Law can be summarised as F= – k x. Here ‘k’ is the spring constant and ‘x’ is the displacement.

A Mirage is a naturally occurring optical phenomenon due to unequal heating of different parts of the atmosphere in which light rays bend to produce a displaced image of distant objects or the sky.

Magma is injected into surrounding rock forming an igneous intrusive.

Actually it is a plutonic formation in which magma present beneath Earth surface deforms the shape of rocks present above it
 

Tin and Silver are malleable and good conductors of electricity. The other combinations have a non metal in them which are bad conductors.

A star is a self luminous astronomical object and shines due to internal radiation from the enrgy sources. All stars are held together by their own gravity called Gravitational force.

All automobiles uses satellite communication channel for their GPS devices.
