At a particular location, the Earth's magnetic field has a magnitude of 5.0 × 10^{-5} T. At that location, Jo is looking out her apartment window, which has an area of 0.8 m^2. The net magnetic flux, from the Earth's field, through the window is 2.0 × 10^{-5} T m^2. What is the angle between the normal (perpendicular) to the window and the Earth's magnetic field?

Truck traveling west on the highway experiences an acceleration to the east. what could be the cause of this acceleration

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
