Atrain starts from rest and accelerates uniformly, until it has traveled 3.7 km and acquired a velocity of the train then moves at a constant velocity of for 410 s. the train then slows down uniformly at until it reaches a halt. what distance does the train travel while it is slowing down? 6.6 km 6.9 km 5.6 km 6.3 km 5.9 km

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

Yvette hangs a 2.4kg bird feeder in the middle of a rope tied between two trees. the feeder creates a tension of 480 n in each side of the the rope.
