An automobile starts at rest and accelerates at 3.5 m/s/s after a traffic light turns green. How far will it have gone when it is traveling at 25 m/s?

Which graph best represents the relationship between the electric current and the rate at which a magnet is turning inside an electric generator?

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

What are the similarities & differences between a thermistor and a light dependent resistor in physics?
