A car with a mass of 1,300 kg travels a distance of 200 m as it moves from one stoplight to the next. At its fastest, the car travels at 20 m/s. What is its
kinetic energy at this point?
O A. 260,000 J
OB. 520,000 J
O C. 13,000 J
O D. 2,600 J

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

Because light travels in a straight line and casts a shadow, isaac newton hypothesized that light is
