What is the gas constant in SI units?
Joules/K.mol
What is Planck's constant dimensionally equal to?
Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.
What are the units of h in the equation E equals hf?
E is energy in Joules (J) or Electron Volts (eV). h is Planck's Constant. When using joules, Planck's constant is 6.63*10^-34 Joule*seconds (J*s). When using electron volts, Planck's constant is 4.14*10^-15 electron volt*seconds (eV*s). f is the frequency of light in inverse seconds or 1/second
What is the base unit of Plancks constant?
Planck's constant relates the energy level of radiation due to electrons moving from one energy level to another, by the formula Energy = (Planck's constant) x (frequency of radiation). Therefore the dimensions of Planck's constant are (energy)/(frequency) which means Joules x seconds In fact Planck's constant = 6.67 x 10-34 joule.seconds.
What is Planck constant value?
Planck's constant was originally defined as the constant of proportionality in the relationship between the energy, E, of a charged atomic oscillator in a black body, and the frequency, ν, of its associated radiation. It is now defined, equivalently, as the quantum of action in quantum physics. Its value is 6.626*10^(-34) Joules seconds.
What is the gas constant in SI units?
Joules/K.mol
What is placnk's quntum constant?
Planck's constant is 6.626 070 040*10^(−34) Joules second.
What is Planck's constant dimensionally equal to?
Planck's Constant is dimensionally equal to Angular Momentum. The unit is Joules second.
Energy of violet photon in joules?
Energy = Planck's constant * Frequency E = (6.626 X 10^-34 J*s)(6.15 X 10^14 s-1) = 4.07 X 10^-19 Joules
How can you derive the expression for calculation of the velocity of sound in a gas at temperature T asqrtYRT?
See the links below. Remember to distinguish where necessary between the universal gas constant R (joules per mole Kelvin) and the particular gas constant R (joules per kilogram Kelvin)
Rydberg constant converted to joules?
2.18x10-18 J This is confusing for students and this book needs to show the derivation. Rydberg's Constant is 1.0974 x 10 7 m-1 which is a distance. Some books say that Rydberg's constant is equal to 2.18 x 10 -18 Joules but this is not correct. They are using (R)times(h)times(c).
Will the value of joules constant be same if AC were used instead of DC?
Joules measure energy (power x time). If the AC voltage is expressed as rms (root mean square) and not peak, and there are no capacitors or inductors in the circuit, then the joules per second (=power ) will be the same.
What is ideal gas constant r?
It is the value of the constant which appears in an equation relating the volume, temperature and pressure of an ideal gas. Its value is 8.314 4621 Joules/(Mol K).
What is meant by constant speed?
minimum avge maintained
The amount of energy in the universe is?
The Total amount of energy in the universe is E=mc2 =1.9 E70 Joules.
You push a food tray 1.5m along a cafrteria table with a constant force of 18N How much work do you do?
27 joules
What are the units of h in the equation E equals hf?
E is energy in Joules (J) or Electron Volts (eV). h is Planck's Constant. When using joules, Planck's constant is 6.63*10^-34 Joule*seconds (J*s). When using electron volts, Planck's constant is 4.14*10^-15 electron volt*seconds (eV*s). f is the frequency of light in inverse seconds or 1/second
