Uma ema pesa aproximadamente 360 n e consegue desenvolver uma velocidade de 60 km/h, o que lhe confere uma quantidade de movimento linear, em kg. m/s, de: dado: aceleração da gravidade = 10 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
