Which of the following would most likely happen if water did not form hydrogen bonds? a. water would exist only as a solid b. water would be able to dissolve all ionic compounds c. water would not expand when it freezes d. water would not exist on earth

(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.)
