The first electric generators used direct current, so they needed to be reversed manually on a regular basis in order to work properly. 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? a)tesla investigated a new problem that no one had considered before. b)tesla used another scientist’s research as inspiration. c)tesla designed a new experimental method for research. d)tesla invented an entirely new concept to replace an inefficient design.

Consider the motion of the balloon and its air contents in terms of momentum. in step 1 above, the total momentum of the balloon and its contents was zero. recall that momentum = mv. both the balloon and the air inside it had a velocity of zero and therefore the total momentum was zero. now think about what happened when the air escaped from the balloon. a certain mass of air accelerated in one direction. in order to keep the total momentum of the system zero, the balloon itself (which has mass) had to accelerate in the opposite direction. use this scenario to you explain why the soda can rotates when the water squirts out of the escape holes. what was your hypothesis concerning the water-filled can? according to your data, do you think your hypothesis was correct? (be sure to refer to your data when answering this question.) summarize any difficulties or problems you had in performing the experiment that might have affected the results. describe how you might change the procedure to avoid these problems. give at least one more example of newton's third law in everyday life.
