To 3 significant figures: h = 6.63*10-34 J s If you have not encountered this type of notification, take 6.63 and divide it by 10 34 times. On your calculator type 6.63, then (usually) press "exp", then type "-34". ENSURE THAT UNITS ARE CONSTANT! This is done in SI units so energy is in Joules (Nm or Kgm2s-2) and seconds, so use: * Kilogrammes for Mass * Seconds for Time * Metres for Distance A suitable conversion system: * 1 parsec = 3.086333*1016 metres * 1 light-year = 9.46728*1015 metres * 1 astronomical unit (earth-sun distance) = 1.49*1011 metres * 1 year = 31557600 seconds * 1 day = 86400 seconds * 1 imperial ton = 1016.0416 kilogrammes * 1 short (US) ton = 907.18 kilogrammes * 1 mile = 1609.283 metres * 1 foot = 0.30479 metres * 1 yard = 0.914365 metres * 1 pound (lb) = 0.454 kilogrammes Hope this helps Paul Hurley

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 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
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.
A photon has a frequency of 4.0 multiplied by 104 Hz?
I assume the equation you're looking for is E=hv or E=hc/lambda. h is plancks constant and c is speed of light in m/s. lambda is in metres
Is it possible to create a perfect circle?
No, it isn't possible to make a perfect circle because of plancks distance.
