Question

Which of the following systems may be adequately described by classical physics?
(a) motion of a cricket ball
(b) motion of a dust particle
(c) a hydrogen atom
(d) a neutron changing to a proton.

Answer 1

Motion of a cricket ball and motion of a dust particle are the one which are adequately described by classical physics

Explanation:

• Classical physics adequately describes the movement of the ball and the movement of dust particles.
• He also describes Newton's law of motion, Newton's law of gravity, the laws of thermodynamics, Maxwell's electromagnetism and Lorentz force.
• Classical physics easily describes the system of celestial bodies such as the sun, the earth, and the moon.
• However, it is not enough to describe particle systems much smaller than 6 to 6 m (for example, atoms, nuclei, and other elementary particles).

Answer 2

(a) motion of a cricket ball

(b) motion of a dust particle

Explanation:

Options A and B can be adequately described by classical physics. Classical physics refers to physics not involving quantum mechanics or the theory of relativity. Physics is the branch of science that deals with things like motion, energy, and force. So classical physics does not deal with atomic and sub-atomic particles. So options C and D are not described by classical physics.

The motion of a cricket ball and dust particle can be described by classical physics.
