The formation of lithium fluoride (seen here) is due to a) a stronger pull by the lithium atom on its valence electron. b) increased stability in the completion of fluorine's outer shell. c) the addition of an outer (higher) energy level in the fluoride ion. d) decreased attraction attraction between the lithium and fluoride ions.

How much heat is required to convert 0.3 kg of ice at 0°c to water at the same temperature

Awave is produced in a rope. the wave has a speed of 33 m/s and a frequency of 22 hz.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
