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.

i think it is true since you can test the answer and can use observations to complete it.

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
