For a bronze alloy, the stress at which plastic deformation begins is 267 mpa and the modulus of elasticity is 115 gpa. (a) what is the maximum load (in n) that may be applied to a specimen having a cross-sectional area of 377 mm2 without plastic deformation? n (b) if the original specimen length is 127 mm, what is the maximum length (in mm) to which it may be stretched without causing plastic deformation?

Antireflective coatings on solar cells are often made by applying a thin film of silicon nitride (sinx), which has an index of refractive of 1.2, on the top of the silicon solar cell, which has a refractive index of about 3.5. however, the sun emits radiation of various wavelengths which the solar cell absorbs, and the antireflective coating can only absolutely minimize the reflection of one of these wavelengths. the coating thickness is chosen to reduce the reflection of green/yellow light (e = 2.2 ev), which is the most intense color in the solar spectrum (shown below). which of the following coatings would minimize reflection of green/yellow light? the answer is 820 nm how? what is the angular width of the central maximum of an electron traveling at 2 x 108 m/s going through a single slit of width 1 mm.
