The angle of reflection made when the angle of incidence of light falling on a plane mirror is 30 degrees is 30 degrees (made with a surface normal to the mirror surface.) The reflected ray will make an angle of (90- 30=) 60 degrees with the mirror surface.
It is referred to as light reflection when a light ray hits a polished or smooth surface and bounces back. The incident light rays hit the surface and are reflected off of it. The beam that returns is referred to as the reflected ray.
The angle of reflection and the angle of incidence, are the angles formed by these light rays when they reflect back or fall on a surface, respectively.

Answer:
The gravitational attraction between two objects in the solar system is greatest when their masses are <em>closer</em>
Explanation:
According to Newton's law of universal gravitation two bodies attract each other with a force directly proportional to the square of their masses and inversely proportional to the square of the distance that separates them, and is directed along the line that joins the bodies. Mathematically it is expressed in the form:
Where:
So, according to the equation, it can be conclude that the gravitational attraction between two objects in the solar system is greatest when their masses are <em>closer</em>
Dalton's theory was identified using light microscope images of atoms.
Answer:
-0.10472
Explanation:
Remember that any <u><em>clockwise</em></u> rotation is considered negative, and any <u><em>counterclockwise</em></u> rotation is considered positive.
The formula for period is:
Solve for and you get:
The period is 60 seconds so make that division and you're left with -0.10472 or -0.10 if significant figures apply (negative because the rotation is clockwise).
