While an airplane is in flight, four forces act on it. thrust is caused by the airplane's propellers pushing through the surrounding air, pulling the airplane forward. drag is caused by the air smacking into the plane's surface, pushing it backward. lift is caused by the air rushing over the wings, pushing it upward. and weight is caused by gravity pulling the plane downward. which force acts on the plane at a distance?

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
