Asmall asteroid with a mass of 1200 kg moves near the earth. at a particular instant the asteroid’s velocity is ⟨ 4.30 x 104, 4.40 x 104, 0 ⟩ m/s, and its position with respect to the center of the center of the earth is ⟨ 9.00 x 106, 10.00 x 106, 0 ⟩ m. the center of the earth (mass = 5.97 x 1024 kg), is at the origin of the coordinate system. what is the (approximate) new momentum of the asteroid 2.00 x 103 seconds later?

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
