Question

2 which forces were the primary focus of teslas work?
a friction and gravity
b magnetism and friction
c gravity and electricity
d magnetism and electricity

Explanation:

Nikola Tesla was a renowned inventor and engineer whose work primarily revolved around electromagnetism. He made significant contributions to the development of alternating current (AC) electrical systems, and his research and inventions were centered on the interaction between magnetism and electricity, such as in the design of electric motors, transformers, and wireless transmission of electrical energy. Friction and gravity were not the primary focus of his work. So the correct option is the one related to magnetism and electricity.

Answer:

D. Magnetism and electricity
