The most important mathematical relationship between voltage, current and resistance in electricity is the Ohm's law: I = V/R<span>,</span> <span>(current=voltage/resistance). We can see, that The magnitude of the electric current is directly proportional to the voltage of the electric field.</span>
Well if the boat initially at rest accelerates at uniformly at 4.0 m/s (squared) then it would be best to muitlply it so 4.0 squared equals 2 by multiplying that by 7.0 your answer would be 14 s
