Why system international consists of seven basic quantities why not eight or six?
The seven basic quantities are selected to allow other quantities to be defined in terms of these measures. It is possible to have 8 or more, but then they would not be independent and at least one could be derived from the others.
Some people argue that even the seven are not independent since distance and time are related by c, the speed of light which is a fundamental constant (under defined conditions). Therefore metre or second can be eliminated as a basic quantity by defining metre = c*time or second = metre/c. However, I contend that this is simply replacing distance and time by either speed and time or by speed and distance so that the number of basic quantities does not change.
What else can I help you with?
What is the basic system international metric system unit of mass?
Kilogram
What are basic quantities and derived quantities?
Basic quantities are physical quantities that are independent and cannot be defined in terms of other physical quantities, such as length, time, and mass. Derived quantities, on the other hand, are physical quantities that are defined in terms of one or more basic quantities, such as speed, acceleration, and force.
What are a basic fundemental quantities?
The basic fundamental quantities in physics are related to energy. They are mass m; charge e; and distance r and speed c. Three fundamental constants relate these fundamental quantities; G the gravitational constant; c the speed of light and z the free space impedance.These quantities and constants are related in the fundamental energy of mass and charge:mass Energy Em = -GmM/r + mcV and charge Energy Ec = -zce^2/4pi r + mcV
What are the differentiate between the basic quantities from derived quantities?
Basic quantities are quantities which can be arrived at without performing any mathematical procedure. Derived quantities are those which can be arrived at only after performing mathematical procedure.
What is basic quantitis?
Basic quantities refers to the quantities from which the others are derived from. This is what is commonly referred to as SI units.
What is the system of a car?
A system usually refers to the audio set up of the vehicle. A basic system usually consists of an amp and a sub woofer.
