if you we're wearing a sweater and you rubbed your hand on it and you would touch a door knob or a metal conductor you would feel a shock why would this happen?

Answer 1

The shock you feel after rubbing your hand on a sweater and then touching a doorknob or a metal object is due to static electricity. Here's how it works:

1. Static Electricity Generation: When you rub your hand on the sweater, friction between your skin and the fabric causes electrons to be transferred from one material to another. This process can result in an imbalance of electrical charge, typically leaving you with a surplus of electrons (negatively charged) on your body.

2. Build-up of Charge: As you continue to rub your hand on the sweater, your body accumulates more charge. This charge tends to stay on your skin because the air is a poor conductor of electricity.

3. Contact with a Conductor: When you touch a doorknob or any other metal object (which is a conductor), the excess charge on your body finds a pathway to discharge. Metal is very effective at conducting electricity, so the electrons on your body suddenly rush into the metal object to equalize the charge difference.

4. Shock Sensation: The rapid movement of electrons is what creates the "shock" sensation. This discharge can be quite quick and may cause a tingling or even a painful feeling, depending on the amount of charge built up.

This is a common occurrence, especially in dry environments where static electricity tends to build up more easily. Wearing certain materials, like wool, can also enhance the effect because they are more prone to creating static charge through friction.

Answer 2

where do the negative charge go when you touch it?

Answer 3

When you touch a metal object, such as a doorknob, the excess negative charge (electrons) on your body moves into the metal object. Here's a more detailed explanation:

1. Charge Transfer: Metal objects are conductors of electricity, which means they allow electrons to flow freely. When you touch the metal doorknob, the excess electrons on your skin are attracted to the metal.

2. Equalization of Charge: The metal doorknob, which is usually at a neutral charge, readily accepts the excess electrons from your body. This transfer occurs to balance the electric potential between your body and the metal object.

3. Resulting Neutralization: After the transfer of electrons, your body's excess negative charge decreases, reducing the static charge that built up on you. The doorknob, after gaining some of your excess electrons, now has a slightly negative charge until it eventually dissipates back to a neutral state.

In summary, the negative charge (electrons) moves from your body into the metal object when you make contact, resulting in a transfer that neutralizes your charge and creates the sensation of a shock.

Answer 6

what does a positively charged object and negatively charged object do when close together?

Answer 7

When a positively charged object and a negatively charged object are brought close together, they experience an attractive force due to their opposite charges. Here’s a more detailed explanation of what happens:

1. Attraction: The positive charge has a deficiency of electrons, while the negative charge has an excess of electrons. The opposite charges attract each other because they create an electric field that pulls the objects closer together.

2. Acceleration Towards Each Other: If they are free to move, the positively charged object will accelerate toward the negatively charged object and vice versa. This attractive force is what facilitates the interaction between the two charged objects.

3. Possible Neutralization: If the two objects touch, there can be a transfer of electrons. Electrons from the negatively charged object can move to the positively charged object, leading to a reduction of charge on both objects. Once the transfer occurs, they may become neutral or less charged.

4. Electric Field Interaction: Even before they touch, the presence of one charged object will influence the electric field around the other, causing a redistribution of charges within nearby neutral objects.

In summary, a positively charged object and a negatively charged object will attract each other, and their interaction can lead to charge neutralization if they come into direct contact.

Answer 8

the pictures below show four electrically charged items.
balloon 1 is filled with positive charges
plastic sheet 1 is filled with negative charges
balloon 2 is filled with negative charges
plastic sheet 2 is filled with positive charges

is a student would rub a glass rod with a piece of silk, giving the rod a positive charge, which of the items will the rod attract?

A. balloon 1, only
B. plastic sheet 1, only
C. balloon 1 and plastic sheet 2
D. balloon 2 and plastic sheet 1

Answer 9

When the glass rod is rubbed with silk, it acquires a positive charge. Charged objects interact based on the principles of electrostatic attraction and repulsion:

• Positive charges attract negative charges.
• Positive charges repel positive charges.
• Negative charges repel negative charges.

Given this, let's analyze the options based on the charged items:

• Balloon 1: Filled with positive charges. (Will repel the positively charged rod.)
• Plastic Sheet 1: Filled with negative charges. (Will attract the positively charged rod.)
• Balloon 2: Filled with negative charges. (Will attract the positively charged rod.)
• Plastic Sheet 2: Filled with positive charges. (Will repel the positively charged rod.)

Based on this analysis, the positively charged glass rod will be attracted to Plastic Sheet 1 (negative charge) and Balloon 2 (negative charge).

Thus, the correct choice is:

D. balloon 2 and plastic sheet 1.

Answer 10

A student conducted an experiment where they made an electromagnet. They used a battery that was 10V, but changed the varying number of turns around the nail. Then the student tested how many pins it attracted. They recorded their data in the table below.
number for turns, N number of pins attracted
20 9
30 14
40 18
50 22
60 27
Based on the investigation the student completed, what would be the best conclusion for this student's work?
Type Answer HERE:
The number of turns on an electromagnet does not determine the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up an increasing number of pins.
The number of turns on an electromagnet does not determine the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up less pins.
The number of turns on an electromagnet does impact the strength of the magnetic field it creates. Therefore more turns on an electromagnet will pick up an increasing number of pins.
The number of turns on an electromagnet does impact the strength of the magnetic field it creates. Therefore less turns on an electromagnet will pick up an increasing number of pins.

Answer 11

Based on the data collected by the student, it is clear that as the number of turns of wire around the nail increases, the number of pins attracted by the electromagnet also increases. This indicates a direct relationship between the number of turns and the strength of the magnetic field produced by the electromagnet.

Thus, the best conclusion for this student's work is:

The number of turns on an electromagnet does impact the strength of the magnetic field it creates. Therefore, more turns on an electromagnet will pick up an increasing number of pins.
