What is density?
Density is a physical characteristic, and calculates of mass per unit of volume of a material or substance. It is a measurement of the quantity of matter in a given volume of something.
The higher an object's density, the higher it's mass per unit of volume. The average density of an object equivalent its total mass divided by its total volume. A denser object (like iron) will have less volume than an equal mass of some less dense substance (like water).

Q. What are the affect does electricity have on the soil? Answer:- Electrical current and ions are able to cause certain molecules (and moisture) to adhere to soil. Large
What is the Directionality of LASER? Directionality: Laser emits light which is highly directional. Laser light is emitted like a relatively narrow beam in an exact direction.
Motion of a swing Periodic Motion : Motion that repeats itself in equal intervals of time is known as periodic motion.
