If plane 'A' and plane 'B' have the same mass, but plane 'A' is designed for exceptional energy transformation, which plane would have the most power?

(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.)

Explain why electric current cannot exist if a current doesn't have a voltage source.
