Two positively charged objects are separated by a large distance. One of the
positively charged objects is replaced by a negatively charged object, and the two
objects are moved closer to each other.
Which of the following occurs in this situation?
a.
The attractive force becomes a repulsive force, which increases as the objects move closer
together.
B.
The repulsive force becomes an attractive force, which increases as the objects move closer to
each other.
C.
The attractive force becomes a repulsive force, which decreases as the objects move closer to
each other.
D.
The repulsive force becomes an attract
creases as the objects move closer to
each other.

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
