The first electric generators used direct current, so they needed to be reversed manually on a regular basis in order to work pr
operly. Nikola Tesla saw this as an inefficient way to produce electricity. As a result, Tesla used the idea of the rotating magnetic field, which had been developed by François Arago, to invent the induction motor, which reverses automatically. How is this an example of a scientist applying creativity to solve a problem? Tesla investigated a new problem that no one had considered before. Tesla used another scientist’s research to help develop his own solution to a problem. Tesla designed a new experimental method for research. Tesla invented an entirely new concept to replace an inefficient design.
If a boat is going East at 15mph and there is a water current going southeast at 45° then the boat is being drifted southward. So since the current is going at an angle then it has a x and y component. So Rx refers to the x-component force of the current and Ry refers to the y-component of the current, and |R| refers to the magnitude of these forces.
