Answer:
The angle of reflection is the angle the reflected rays make with a perpendicular line to the reflecting surface.
Explanation:
Reflection It is the change of direction suffered by a luminous ray when hitting the surface of an object. The angle of reflection is that which is formed by the reflected ray and the normal vector to the study surface
Answer:
AN average heavy weight is 175 pounds. The heaviest weight ever recorded though was 1,400 pounds, or 635 kilograms.
Answer: One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter changes or controls and is assumed to have a direct effect on the dependent variable.
Work = (force) x (distance)
40,000 J = (20 N) x (distance)
Distance = (40,000 J) / (20 N)
= 2,000 meters
= 2 kilometers.
(20 N is not a huge force when it's being used to move a car.
It's only about 4.5 pounds.)
Well, an equilibrium means that no force are changing an object's inertia (current state of motion).
