We would like to use the relation v(t)=i(t)r to find the voltage and current in the circuit as functions of time. to do so, we use the fact that current can be expressed in terms of the voltage. this will produce a differential equation relating the voltage v(t) to its derivative. rewrite the right-hand side of this relation, replacing i(t) with an expression involving the time derivative of the voltage. express your answer in terms of dv(t)/dt and quantities given in the problem introduction.

(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.)
