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.

B-Tesla used another scientist’s research as inspiration.

Explanation:

The scientific world is really interesting. At all times, scientists are seeking to establish new theories, reformulate old theories, or use knowledge already disseminated to create a technology that will solve a problem of the human race, or create a technology that makes people's lives easier.

An example of the use of a knowledge already disclosed to form a technology was made by Nikola Tesla. Tesla, using François Arago's research as inspiration, invented the induction motor, which reverses automatically. This engine was a revolution that allowed to replace the first electric generators that used direct current; therefore, they needed to be manually reversed regularly to function properly.

the correct answer in apex is tissue development, i know because i just had this question

igneous rocks are formed by solidification of cooled magma (molten rock), with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.  

the composition depends on the source magma. there are almost a thousand types of composition found till now.  

hope this
