Alarge block is being pushed against a smaller block such that the smaller block remains elevated while being pushed. the mass of the smaller block is =0.45 kg. it is found through repeated experimentation that the blocks need to have a minimum acceleration of =16 m/s2 in order for the smaller block to remain elevated and not slide down. what is the coefficient of static friction between the two blocks?

Glass is transparent to visibile light under normal conditions; however, at extremely high intensities, glass will absorb most of the light incident upon it. this works through a process known as multiphoton absorption. in this process, several photons are absorbed at the same time. if very intense light whose photons carry 2ev of energy is shined onto a material with a band gap of 4ev, that light can be absorbed through two-photon absorption, because two photons have the right amount of energy to bridge the band gap. what is the minimum number of photons of 800-nm light that are needed to equal or exceed the band gap of fused silica glass
