@hallsofivy - thanks for the reply its 105*10^4 nm =105*10^-5 m because nm = 10^-9
thanks a lot it helped
sorry bro, will i not have to convert the 500g to Kg?
cheers
ere thanks a lot tiny-tim
please i still don't get much about it, see what i did, i found the distance on the ground from the bottom of the wall to the bottom of the ladder, its 3 metres then i calculated the angle at which the ladder is leaning on the wall...its 53.13 degress...
The specific heat capacity of water is 4.184 J/g°C. A 500g sample of water is exposed
to the light emitted by a CO2 laser. The wavelength of the laser light is 1.06 × 104 nm.
Assuming that all of the light energy is converted into heat, calculate the number
moles of photons required to...
A 5 metre long ladder in equilibrium leans against a wall, touching it 4 metres above
the ground. The ladder’s mass is uniformly distributed and is equal to 10kg. An 80kg
man stands on the centre rung of the ladder. Assume the wall is frictionless but that
the ground can exert a frictional...
