Jorge inflates a beach ball to a volume of 4L in his air-conditioned house where the temperature is 18 degrees Celsius. That afternoon he takes the beach ball to the beach with some friends. The temperature at the beach is 32 degrees Celsius and the air pressure at the beach is the same as it was as Jorge's house. What will happen to Jorge's beach ball when he is at the beach?

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.
