1) Inhabitants of the fifth planet in a solar system on the other side of the Galaxy measure distance in units called “ladoladelums” and time in units called “forevers”. They observe that, a) all the planets in their solar system are much smaller than their Sun,
b) all planets have nearly circular orbits,
c)the fourth planet is about 32 ladoladelums from their Sun and completes one revolution in about 47 forevers, and
d) the third planet completes one revolution in 13 forevers.
Question: About how far from their Sun does the third planet lie?

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
