Q. What would be the final temperature of 100 g of 16°C water when 107 g of 40°C iron nails are submerged in it? (The specific heat of iron is 0.12 cal/g °C. Here you should equate the heat gained by the water to the heat lost by the nails.)

Q. Why does the existence of a cutoff frequency, below which no photoelectrons are ejected from a metallic surface, support the photon theory rather than the wave theory of light?
