A particle’s position along the x-axis is described by the function x(t) = A t + B t2,

where t is in seconds, x is in meters, and the constants A and B are given below.

Randomized Variables
A = -4.9 m/s
B = 6.9 m/s2

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

The softest and hardest minerals are: softest hardest
