Directions: Read the following information and give answer.A rat runs 20' towards East and turns to right, runs 10' and turns to right runs 9' and again turns to left, runs 5' and then turns to left, runs 12' and finally turns to left and runs 6' Now, which direction is the rat facing?
Correct answer: C. North
- A. East
- B. West
- C. North
- D. South
Explanation
To determine the final direction the rat is facing, follow these steps:The rat starts by running 20' East.It turns right (now facing South) and runs 10'.It turns right again (now facing West) and runs 9'.It turns left (now facing South) and runs 5'.It turns left again (now facing East) and runs 12'.Finally, it turns left (now facing North) and runs 6'.After these movements, the rat is facing North. The rat makes a total of four left turns and two right turns. The final orientation is determined by the cumulative effect of these directional changes.Other options such as East, West, or South are incorrect because they do not match the final orientation after considering all movements and turns.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
