All of the following are examples of energy transformations EXCEPT OB O A. Electric energy from an outlet becomes electromagnetic energy when it is used to power a light bulb. Ajack in the box is cranked down until the spring inside is compressed. The spring releases turning elastic potential energy into kinetic energy when the toy moves. O C. Stored potential energy in a lighter is ignited to create light and thermal energy. OD. A child on a sled posesses kinetic energy as they slide down a snowy hill.​

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.

Slab pull” is a type of tectonic plate movement that occurs due to the forces of mantle convection and results in the subduction of the lithosphere true or false
