Which statement correctly describes the relationship between power, voltage, and current? if voltage is increased, and no other changes are made, power will decrease. if voltage is increased, and no other changes are made, power will increase. if current is decreased, and no other changes are made, power will increase. in order to decrease power, voltage must be decreased.

What is required for an electric charge to flow through a wire? zero resistance in the wire a balance of electric potential high resistance in the wire a difference in electric potential

If the ama of the inclined plane below is 2, calculate the ima and efficiency. ima = efficiency =

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.
