  • Question 1
    4 / -1

    Which of the following statements is not correct?

    Solution

    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.

  • Question 2
    4 / -1

    Solution

    Classical physics is applicable to macroscopic world.

  • Question 5
    4 / -1

    Classical physics does not include subjects like

    Solution

    In classical theory theories of mechanics, relativity, field theory is not included. These are the category of subject which comes under Quantum mechanics(Physics) where we study small particles and classical physics also include electromagnetism (light, heat).
