What is the physical significance of planks constant?
Planck's Constant (abbreviated as 'h'), when first "discovered," was found to be the ratio of the energy of an individual photon to the frequency of that photon's light. In other words, the energy of a photon is equal to h times the photon's frequency. It has since been found that h fits into a wide variety of formula that allow us to understand the Universe we happen to live in. Without this constant, a lot of our Universe would be incomprehensible.
A ball is dropped and its motion recorded It is found that the increase in speed is uniform for each second it falls Which inference do these observations support?
If the increase in speed is uniform, this means that the slope of the function of speed over time is constant. This means that acceleration is constant.
What is the difference between constant and non-constant motion?
Acceleration is the difference between constant and non-constant motion.
What is constant displacement?
In Wien's experiment it was found that when the temperature of the source increases, then the wavelength for which the radiant energy becomes maximum decreases. This displacement towards the lower wavelength side as temperature increases is termed as displacement law. So if T, the temperature of the source in kelvin and lambda m is the wavelength for which the energy is maximum. Then lambdam *T = constant. This constant is known as Wien's constant, whose value is 5.67 x 10-8 mK.
When the velocity of a particle is constant its acceleration is also constant?
Its acceleration is zero, which is constant
Why did Einstein have to find a gravitational constant?
The gravitational constant was found by Newton, not Einstein.
How do you use the word constant in a short sentence?
I found her gum-chewing to be a constant annoyance.
What is a coefficient and where are they found in a reaction?
a numerical or constant quanity and found right next to the element.
Can the spring constant be found by the gradient of the graph?
The answer depends on what the graph is of!
Is constant hunger an early sign of pregnancy?
yes - I had constant strong hunger in the days leading up to my period, and then I found out I was pregnant ;)
What is the purpose of the reduced Planck constant?
The reduced Planck constant simplifies the mathematics found in quantum physics calculations by adding a 2pi term into it. Instead of worrying about that 2pi constant, formulas using the reduced Plank constant have it built in.
Why is the background count is not constant?
The background count for radioactivity is not constant because of radioactive decay. Natural radioactivity is found everywhere, in the air and on the ground we walk on.
When was gravitational constant found?
Although Newton included the gravitational constant in his law of universal gravitational constant, its value was not determined until some 70 odd years after his death, when Henry Cavendish measured it in 1798.
What did Charles find about volume and temperature?
Charles found that when the temperature of a gas is increased at constant pressure, its volume increases. When the temperature of a gas is decreased at constant pressure, its volume decreases.
Where are most robots found?
Mainly in factories because their work is constant and they don't need pay or benefits.
What features of baroque music were NOT found in music of the classical period?
a constant mood of the song was never changed
Vanadium at 20c is Bcc and has an atomic radius of 0.143 nm calculate a value of its lattice constant a in nanometers?
For all BCC lattice structures, the Lattice constant (a) can be found by : a = (4r) / sqrt(3)
