Which of the following statements is not correct. ?

  1. Physics is the study of nature and natural phenomena.

  2. Physics and technology are not related to each other.

  3. Electrodynamics deals with electric and magnetic phenomena associated with charged and magnetic bodies.

  4. The physical quantities that remain unchanged in a process are called conserved quantities.

B Correct answer
Explanation

Complex technologies are making use of more rarefied physical concepts. Physics describes the things that are possible in the universe, and technology is eventually built to do work within that which has been discovered by physics. This interplay also works in reverse. Modern physicists are frequently making use of extremely high-tech machines and processes. For example, the Large Hadron Collider in Switzerland is the world's largest particle accelerator. It can be operated at higher energies than any previous one. It was built explicitly to perform experiments in particle physics.

Thus Physics and technology are very much related to each other. So statement B is not appropriate. Although the other three statements are very much correct and factful.

Thus option B is correct.

What is the two principal thrust in Physics?

  1. Unification and Reduction

  2. Unification and Oxidation

  3. Magnification and Reduction

  4. Simplification and Reduction

A Correct answer
Explanation

The principal thrust in physics is to unity all the fundamental forces into a single framework and reduce the no.of different theories to minimal no. of models which can describe a great number of a phenomenon. (a)

where Unification is the act of unifying the different laws valid for different phenomena into a single theory that explains all the different phenomena.

The reduction is breaking down of a complex system into simple constituent systems to so that laws of physics can be applied to these systems and we can understand the working of the complex system.
