When viewing a piece of art that is behind glass, one often is affected by the light that is reflected off the front of the glass (called glare), which can make it difficult to see the art clearly. One solution is to coat the outer surface of the glass with a thin film to cancel part of the glare. Requried:
a. If the glass has refractive index of 1.62 and you use TiO2, which has a refractive index of 2.62 as the coating, what is the minimum film thickness that will cancel light of wavelength 505 nm?
b. If this coating is too thin to stand up to wear, what other thickness would also work? Find only the three thinnest ones.

Modify the equation fδt=δ (mv) to find the force of friction.

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
