Answer:
A force has both magnitude and direction, making it a vector quantity. It is measured in the SI unit of newton (N). Force is represented by the symbol F. The original form of Newton's second law states that the net force acting upon an object is equal to the rate at which its momentum changes with time.
Other units: dyne, pound-force, poundal, kip, kilopond
SI unit: newton (N)
Common symbols: F→, F, F
Answer:
Law of conservation of momentum states that "The total momentum of an isolated system always remains constant"
Or
"In an isolated system the total momentum of the interacting bodies remains constant before and after collision or interaction".
Answer:
A substance known to reflect red and blue light, and illuminated by green light, will have all the three primary light colors. The color it would reflect is white.
Explanation:
In visible light spectrum, a combination of red light and blue light gives magenta. Also a combination of red and green lights gives yellow light. and when green and blue lights mix the resulting light color is cyan.
However, if these three primary colors mix in equal proportion, we will have a neural color or white color and in the absence of these primary colors we will have black.
Thus, a substance known to reflect red and blue light, and illuminated by green light, will have all the three primary light colors. The color it would reflect is white.
