Would these two waves produce a standing wave? yes, because the waves are traveling in opposite directions yes, because the waves are traveling in the same direction no, because the waves do not have the same wavelength no, because the waves do not have the same amplitude

(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.)
