Which of the following is an example of an electric force acting at a distance?

a.
pam applies a force to the head of a nail by pounding it with a heavy, iron hammer. the nail then wedges itself between the fibers of a wooden board.

b.
pam jumps out of an airplane. air rushes past her body a very high speeds as she falls. she then opens her parachute and feels an upward force.

c.
pam rubs a glass rod with wool, then moves the rod over a pile of small paper scraps. the scraps leap into the air and stick to the rod.

d.
pam applies a twisting force to the steering wheel of her car. this force pushes on tubes filled with fluid, which then push the wheels of her car to one side.

The correct answer is option C

The electric force acting at a distance can be observed when someone rubs a glass rod with something woolen then the rod is taken away from the woolen material. The piece of paper leaps into air and sticks on to the rod.

This is due to the electrostatic force of attraction that the paper sticks on the glass rod.

The glass rod gets charged and then the opposite charges in the paper and rod started acting and as a result of this paper sticks on the rod.

sulfur dioxide

explanation: acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. these substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

you didn't give any options but heres what i can tell you: an inference is likely to change based on additional observations. the latter is something that you have seen or sensed using your sensory organs while the former is like a conclusion out from what you have observed.
