St 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?
O Tesla investigated a new problem that no one had considered before.
O Tesla designed a new experimental method for research.
O Tesla invented an entirely new concept to replace an inefficient design.
O Tesla used another scientist's research to help develop his own solution to a problem.

Tesla used another scientist’s research as inspiration. (The last one)

Explanation:

Tesla used someone elses idea of a rotating magnetic field. This dosen't mean he plagarized another scientist work, but he needed the scientific concept to create something new.

explanation:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
