led is used to determine Plancks constant
What is the unit that time is measured by?
In the International System of Units (SI Units), time is measured in seconds.
Weight is measured in units called?
Weight is measured in units called newtons , while mass is measured in units called grams and kilograms.
What does area units measure?
Area is measured in square units.
Sometimes force is measured in SI units International System of Units called?
In SI system, it is measured in Newton(N).
Why LED is used to determine planks constant?
led is used to determine Plancks constant
If the frequency of ultraviolet light is 2.53 x 10 power of -7 plancks constant is 6.63 x 10 power of -34 and the work function is 3.6eV what is the maximum kinetic energy?
you need units
Is gas constant equal to planks constant?
No, gas constant is having a value of 8.314Jk-1mol-1 Whereas plancks constant has a value of 6.6*10-31
What was Niels Bohr's formula?
(E) Photon=E2-E1= hv h=Plancks constant v=frequency
What is unifrom motion regular motion?
motion is always measured in meters > uniform - constant - unchanging constant speed (SI units - metres per second)
Why is perimeter measured in units and area measured in sq units?
Because a perimeter is measured in linear units while an area is measured in square units.
Is the area measured in cubic units?
No, volume is measured in cubic units, area is measured in square units.
What is the wavelength of an electron moving with a velocity of 2.5 x 108 cm s1?
Wavelength = Plancks constant / (Mass x Velocity)
The energy given off by burning fossil fuels can be measured in?
If you refer to the units, energy is measured in joules.If you refer to the units, energy is measured in joules.If you refer to the units, energy is measured in joules.If you refer to the units, energy is measured in joules.
Why is a solid figure measured in cubic units?
The length, width, or height of a solid figure is measured in units of length. The area of the figure's outside surfaces is measured in squared units of length. The volume of space filled by the figure is measured in cubed units of length. The mass of the figure is measured in units of mass. The weight of the object is measured in units of force. The age of the figure is measured in units of time. etc.
What do you need to know to calculate the frequency of a wave?
wavelength since frequency =hc/lambda h=plancks constant and c=velocity of light
Who measured the gravitational constant G?
Cavendish measured the gravitational constant "G".
