The threshold wavelength for cesium oxide is 7,000 angstroms, and that for tungsten is 2,730 angstroms. A chemistry student was testing cesium and tungsten and found that cesium emits light with a particular wavelength, but tungsten does not. What would be the most reasonable range of angstroms for the wavelength of the light that the student used? Explain your answer.

(a) assume the equation x = at^3 + bt describes the motion of a particular object, with x having the dimension of length and t having the dimension of time. determine the dimensions of the constants a and b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.) (b) determine the dimensions of the derivative dx/dt = 3at^2 + b. (use the following as necessary: l and t, where l is the unit of length and t is the unit of time.)
