Answer:
The interactions of electricity and magnetism are difficult to explain in nontechnical terms. This is primarily because one has to describe the interactions in terms of invisible "force fields" which shift, expand, contract, strengthen, weaken, and rotate in space, and these are very difficult to describe adequately in verbal terms. In mathematical terms, coupled sets of three-dimensional vector differential equations are required, and these are also quite difficult to visualize.

Answer:
(a) -550 °F
Explanation:
No temperature below absolute zero is possible.
Absolute zero on the Fahrenheit scale is -459.67 °F. A temperature of -550 °F is less than that, so is not physically possible.
