Asurface completely surrounds a 3.3 × 10-6 c charge. find the electric flux through this surface when the surface is (a) a sphere with a radius of 0.76 m, (b) a sphere with a radius of 0.18 m, and (c) a cube with edges that are 0.46 m long.

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

Examine the nuclear reacti why is this classified as a nuclear reaction rather than a chemical reaction? it is not balanced. a new compound is formed. a change has occurred in a nucleus. a new element has been formed.

Explain the difference in reactivity of the elements based on their electron configurations.
