Jorge inflates a beach ball to a volume of 4L in his air-conditioned house where the temperature is 18oC. That afternoon he takes the beach ball to the beach with some friends. The temperature at the beach is 32oC, and the air pressure at the beach is the same as it was at Jorge’s house. What will happen to Jorge’s beach ball when he is at the beach.

Astone dropped into a well is heard to strike the water after 8seconds. find the depth of the well if the velocity of sound is 350m/s

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

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
