Expression for ду (a) use the ftr to find an and hence show that t асу =t ат? д t 6 marks] (b) within a limited range of temperatures and volumes, a certain gas satisfies the equation p(v - b) = rt. it is found that at a fixed volume vo within this range, cy a where a is constant. use this information to show that cy = a for all temperatures and volumes in this range

What are chlorofluorocarbons and what impact do they have on the atmosphere?

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.

When is a current produced? when the terminals of an electrochemical cell are connected by a wire if the electric circuit is opened in an electrochemical cell if the electrolyte is removed from an electrochemical cell when the electrodes are reversed in an electrochemical cell
