Answer:
1. 23°
2. 65°
Explanation:
1.
The law of reflection provides that for the same medium, the angle of reflection equals the angle of incidence.
Similarly, here, angle of incidence and reflection will be 46°÷2=23°
2. Since the normal, angles of reflection and incidence lie on the same plane and also the angles of reflection and incidence are equal then the angle between the plane of the mirror and the reflected beam will be given by 90-25=65°

Answer:
Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay. All the known forces of nature can be traced to these fundamental forces
