Based on the graph below of the power output of a solar panel. A class studied the electricity produced by the solar panel their school for one day. They read the graph below on their computer. Which of the following conclusions can they derive from studying their graph? The maximum power output for this panel on this day was about 0.9 kilowatts.
The cloudier the day, the less energy is produced especially in the afternoon.
The hotter the day, the more energy is produced especially in the afternoon.
The solar panel produces no energy at 8:00 AM.

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 passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection
