An electric insulator is a material: A. Containing no electrons B. Through which electrons do not flow easily C. That has more electrons than protons on its surface D. Cannot be a pure chemical element

(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.)

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt
