and magnetism
1.
Which of the following statements is true.
a. Electricity and magnetism are not related
at all and are two forces that act
independently from each other
b. Electricity and magnetism are not related
but do act together to combine forces
and charges.
c. Electricity and magnetism are related and
are the same force but act in different
ways depending on the situation
d. Electricity and magnetism are related but
not the same force but they do act
together in various scenarios.

Jimmy rubs a balloon in his sweater and then
releases the balloon. The balloon stays on his
sweater without his hand holding it. Which
statement best describes why the balloon is
staying.
a. There is an attraction between negative
charges causing the balloon to stay on the
sweater.
