6. describe in detail why a comb drawn through hair attracts a tiny piece of paper. use appropriate…

6.

Brief Explanations:

When a comb is drawn through hair, friction causes electrons to be transferred from the hair to the comb. The comb becomes negatively - charged. The tiny piece of paper is electrically neutral. When the charged comb is brought near the paper, it causes the electrons in the paper to redistribute. The side of the paper closest to the comb becomes positively charged due to the attraction of the comb's negative charge. Opposite charges attract, so the negatively - charged comb attracts the positively - charged side of the paper.

Answer:

When a comb is drawn through hair, friction leads to electron transfer making the comb negatively charged. This causes charge redistribution in the neutral paper, with the side near the comb becoming positive, and thus the comb attracts the paper due to the attraction between opposite charges.

Brief Explanations:

The three types of particles that make up all atoms are protons, neutrons, and electrons. Protons are located in the nucleus of the atom and have a positive charge (+1 elementary charge). Neutrons are also in the nucleus and have a neutral charge (0 elementary charge). Electrons orbit the nucleus and have a negative charge (- 1 elementary charge).

Answer:

Protons: located in the nucleus, positive charge (+1 elementary charge). Neutrons: located in the nucleus, neutral charge (0 elementary charge). Electrons: orbit the nucleus, negative charge (-1 elementary charge).
