Wavelengths of incoming solar radiation are the wavelengths of reradiated heat. question 2 options: faster than shorter than twice the size of the same size as

How much heat is needed to change the temperature of 3 grams of gold (c = 0.129 ) from 21°c to 363°c? the answer is expressed to the nearest whole number.

Red light strikes a metal surface and electrons are ejected. if violet light is now used with a 10% greater intensity, what will happen to the ejection rate (number of ejected electrons per second) and the maximum energy of the electrons? a) greater ejection rate; same maximum energyb) same ejection rate; greater maximum energyc) greater ejection rate; greater maximum energyd) same ejection rate; same maximum energye) none of the above answers are correct

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.
