If a person was interested how light passes through clear substances, what field of science would be the best course of study? A. thermodynamics
B. quantum mechanics
C. optics
D. electromagnetism

C. Optics

Explanation:

We need to understand each of the fields first.

A. Thermodynamics: Thermodynamics is the branch of science the deals with the transfer of heat as it is clear from the name. Thermo means Heat and Dynamics means motion,

B. Quantum Mechanics: It is the study of the physical laws and properties in nature, at atomic or even sub-atomic level.

C. Optics: Optics is the branch of physics that deals with the nature of light light and the phenomena related to the light.

D. Electromagnetism: It is the branch of physics that deals with the interaction of electricity and magnetism.

Since, optics deals with the phenomena of light. Hence, person interested in how light passes through clear substances, should study:

C. Optics

option number c is the right answer.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
