Question

what is the S.I AND C.G.S unit of volume?

Answer 1

Length, mass, and time are the three fundamental dimensions on which the measurement of all physical quantities is dependent.

Physics is a science based upon exact measurement of physical quantities that are dependent upon three fundamental dimensions. The three fundamental or primary dimensions are mass, length, and time. These three fundamental units must be understood in order to lay the foundation for the many concepts and principles presented in this material.

Mass

Mass is the amount of material present in an object. This measurement describes "how much" material makes up an object. Often, mass and weight are confused as being the same because the units used to describe them are similar. Weight (a derived unit, not a fundamental unit) is a measurement that describes the force of gravity on the "mass" of an object.

Length

Length is the distance between two points. The concept of length is needed to locate the position of a point in space and thereby describe the size of a physical object or system. When measuring a length of pipe, the ends of the pipe are the two points and the distance between the two points is the length. A typical unit used to describe length is the "foot."

Answer 2

Answer:

force which produces unit acceleration in unit mass In SI, force is measured in newton (N).

Force is said to be I N, if it produces an acceleration of I ms-² in a body of mass 1 kg.

The C.G.S. unit of force is dyne. If m = 1 g;a = | cms-² : F= l dyne.

Hence, force applied is said to be 1 dyne if it produces an acceleration of 1 cms-² in a mass of 1g, 1 N = 10^-5 dyne.
