In physics intensity is the energy density (that is, the energy per unit volume) multiplied it by the velocity at which the energy is moving. The resulting vector has the units of power divided by area, that is in watts per m². It is possible to define the intensity of the water coming from a garden sprinkler, but intensity is used most frequently with waves (i.e. sound or light).
Magnitude is a measure of the size of a mathematical object.

Earthquakes are measured either by Modified Mercalli Scale, if one is interested in building behaviour; or the Richter scale (or its modifiers) if one is concerned with the source energy of earthquakes.
Stars also have a magnitude scale for comparison.

What is unit for magnitude?
A Bar
If a vector quantity is divided by its magnitude the vector obtained is called?
A unit vector.
Do physical quantities have numerical magnitude and a unit?
Many do. For instance, you would probably agree that your own height and weight are physical quantities. Each of these has a magnitude or size and a unit of measurement. They might be, say, 157 cm and 50 kg.
Which units can velocity be expressed?
(any unit of length) / (any unit of time) is a unit that can be used for the magnitude (size) of velocity, and must always be accompanied by a description of direction. Without it, all you have is a speed, not a velocity.
How understand that all physical quantities consist of numerical magnitude and units?
Basically, a unit is a type of standard against which a measurement is compared. For example: the standard unit of length is the meter. If you claim that your house (for example) measures 9 meters from north to south, then you are really claiming that the length of your house is 9 times as much as a meter.
What is the SI unit for the magnitude?
A magnitude is a pure number - with no SI unit.
What is magnitude unit?
A Bar
What is unit for magnitude?
A Bar
The si unit used for magnitude?
A magnitude is a number and so has no units.
Why unit vector has magnitude one?
That's what "unit" means.
What is the standard unit of amount?
magnitude
Can a unit vector have any components with magnitude greater than unity?
No, by definiton, a unit vector is a vector with a magnitude equal to unity.
Define the unit vector?
The unit vector is a vector whose magnitude is 1.
What is unit vector in physics?
a vector having unit magnitude and have a certain direction.
What is the unit for mersuring earthquake?
Richter scales are used to measure the magnitude of an earthquake. There is no specific unit used for earthquakes. I hope this helps. =)
What is a unit vector?
It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.It is a vector whose magnitude is 1.
Can Distance be fully described with a magnitude and a unit?
Distance can be fully described with a magnitude and a unit. It is a scalar quantity, which means it has a magnitude (numerical value) but not a direction. A related quantity is displacement, which is the straight line distance from a starting point to an ending point. Displacement is a vector quantity, so it can only be fully described with a magnitude, a unit, and and direction.
