the seven basic physical quantities ;lenght, mass,time temperature,electric currrent ,luminous intensity and amount ofsubstance which areindependent of any other quantities for their measurement are clled
The unit of a physical quantity in physics is a standardized way to express and measure that quantity. Units give the quantity a numerical value and specify the scale at which it is being measured. Units are essential for consistency and clarity when communicating about physical quantities.
When the numerical value of a quantity is equal to the unit of that quantity, it means that the quantity being measured is equal to 1 in that unit. This often simplifies calculations and conversions in physics and mathematics.
Inertia is not a physical quantity but rather a property of matter. It is the tendency of an object to resist changes in its motion. Its SI unit is the kilogram (kg).
A light year is a unit of distance, not a physical quantity. It represents the distance that light travels in one year in a vacuum.
The physical quantity that has the unit joule per coulomb is electric potential, which is measured in volts. Electric potential is a measure of the electric potential energy per unit charge at a point in an electric field.
A standard use for a measurement of a physical quantity is called the unit of that physical quantity
The unit of a physical quantity in physics is a standardized way to express and measure that quantity. Units give the quantity a numerical value and specify the scale at which it is being measured. Units are essential for consistency and clarity when communicating about physical quantities.
the physical quantity is distance and unit is meters
the formula showing the relation between the unit of any physical quantity n the unit of fundamental physical quantity is called dimensional formula.........of dat quantity
pressure
It is a commercial unit of energy.
The physical quantity is simply called area. The official unit (in SI) is the square meter.
The physical quantity with the SI unit JC^-1 is the electric permittivity. It is a scalar quantity because it describes the ability of a material to store and transmit electrical energy.
Electric flux.
When the numerical value of a quantity is equal to the unit of that quantity, it means that the quantity being measured is equal to 1 in that unit. This often simplifies calculations and conversions in physics and mathematics.
Density.
To measure a physical quantity correctly and need to compare it with some standard quantities. Thus a standard unit is needed to measure a quantity correctly.
