Sam recently moved to a new town and has been feeling nervous about starting a new school. Her body has reacted to the stress by signaling her to eat more. She does not need to overeat. How can she better manage this stress?

Why do electron microscopes have higher resolving power than light microscopes?

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
