Dear All please do help me out - thanks. How much heat and light energy is produced by a 100W electric lamp in 5 minutes? Solutn = I tried this using Energy = power x time 100 x 5min = 100 x 300 sec = 30,000J - Pls do I got the answer? You will see it

An incident light is monochromatic and of wavelenght 600nm, the kinetic energy of the electron is 2.56 x 10^(-20)J. For light of wavelenght 400nm, it is 1.92 x 10^(-19)J. Use the above information to estimate the value of Planck's constant,h and the work
