The woman was standing on a cliff 30 meters above where she landed. There was a safety fence 4 meters from the cliff edge that would have prevented her from taking a long distance to run and leap off the cliff. She landed 12 meters away from the base of the cliff. Her launch speed was calculated to be 4.86 m/s, meaning that to travel those 12 meters, she had to be traveling at 10.87 miles per hour (or moving faster than a runner at a 5.5 minute mile pace) as she left the cliff. Put all this information together. Why did forensic scientists determine that the woman’s body was thrown instead of concluding that she jumped off the cliff?

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.
