A physical constant is a physical quantity that is generally believed to be both universal in nature and constant in time.

And we know the solar output's not constant through time.

The square of the amplitude is proportional to the intensity of the wave.

Victoria disliked the trips the constant round of public appearances made her tired and ill, and there was little time for her to rest.

Time domain considerations This section relies on knowledge of e , the natural logarithmic constant .

These systems do have a chance of breakdown per unit of time, that increases from the moment they begin their existence.

Since all wires have some self inductance and resistance, all circuits have a time constant.

It is also known as the universal gravitational constant, Newton's constant, and colloquially as Big G. It should not be confused with small g ( g ), which is the local gravitational field (equivalent to the free fall acceleration), most commonly for that at the Earth's surface.

If only the electric field (E) is non zero, and is constant in time, the field is said to be an electrostatic field.

constant primary balance

The question on race has adapted over time to include the ever changing racial and ethnic makeup of the country.

or continuous wave ), or may be modulated so as to vary with time and or position.

The impulse response for the capacitor voltage is formula_25where u ( t ) is the Heaviside step function and formula_26is the time constant.

The impulse response for the inductor voltage is formula_21where u ( t ) is the Heaviside step function and formula_22is the time constant.

It's a constant struggle.

Keeping a constant depth requires continual operation of either the depth control tanks or control surfaces.

The material constant in Curie's law is known as the Curie constant.

The strength of the electromagnetic interaction varies with the strength of the energy field.

It states Reasonable machines can simulate each other within a polynomially bounded overhead in time and a constant factor overhead in space .

Poorer sanitation of the time resulted in a constant exposure to the virus, which enhanced a natural immunity within the population.

By varying the current and the length of the wire he deduced that the heat produced was proportional to the square of the current multiplied by the electrical resistance of the wire.

And they are in an active blood feud.

The self was not constant.

Will the population remain the same?

Female driver, constant danger.

Tom made steady progress.

A familiar example is the concept of the graph of a function.

It's a constantly falling process.

Will our tastes be the same?

There is a constant tension in the air.

Fog is also a constant.

Close to the surface of the sample, attractive forces can be quite strong, causing the tip to snap in to the surface.

The city's location behind the mountain range and highly variable winds mean that the weather is quite changeable from one day to the next and from year to year.

During the evaluation of a limit, the constant remains the same as it was before and after evaluation.

These equations show that a series RC circuit has a time constant, usually denoted formula_54 being the time it takes the voltage across the component to either rise (across C) or fall (across R) to within formula_55 of its final value.

These equations show that a series RL circuit has a time constant, usually denoted formula_44 being the time it takes the voltage across the component to either fall (across L) or rise (across R) to within formula_45 of its final value.

It's been a remorseless, steady increase.

And they say, Oh, yeah. Constant acceleration.

Why has there been such steady interest ?

Constant dripping wears away a stone.

He is in constant dread of his father.

γ is the Euler Mascheroni constant.

The energy comes from the gravitational binding energy of a neutron star.

This allows for a steady supply of cells.
