JUST NEED TO CONFIRM AN ANSWER The diagram on the right shows a block being pulled across a level surface by a tension force T in a rope that is at angle θ above the ground. The normal force on the block Fn and weight of the block W are also shown. Which of the following would happen if the magnitude of the tension force T stays the same, but the angle θ increases?
A. The weight of W of the object increases
B. The weight of W of the object decreases
C. The normal force Fn on the object increases
D. The normal force Fn on the object decreases.

How will each of the following changes in demand and/or supply affect equilibrium price and equilibrium quantity in a competitive market; that is, do price and quantity increase or decrease, or are the answers indeterminate because they depend on the magnitudes of the shifts?

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
