What else can I help you with?
When you rub a ruler with a cloth why does it become charged?
it generates magnetic field and thus get charged
What charge does a plastic ruler have?
A plastic ruler typically does not have a charge as it is an insulator and does not conduct electricity. If a ruler were to become charged, it would likely carry a small amount of static electricity, which could be either positive or negative depending on the materials it has come into contact with.
What will happen if a glass ruler is rubbed vigorously on a woolen cloth?
Rubbing a glass ruler on a woolen cloth will create a static charge on the ruler due to the triboelectric effect, where electrons transfer between the materials. The glass ruler will become negatively charged as it gains electrons from the woolen cloth, resulting in static attraction to objects with a positive charge.
What is static electricity and balloons?
Static electricity is a build-up of electric charge on the surface of an object. When you rub a balloon against your hair, electrons transfer from your hair to the balloon, creating a charge imbalance. This causes the balloon to stick to objects or your hair because of the attractive forces between the charged balloon and uncharged objects.
Is plastic ruler gets attracted towards pieces of paper when rubbed with oily hair?
Yes, when a plastic ruler is rubbed with oily hair, it can become statically charged. This static charge may attract lightweight objects like pieces of paper due to the electrostatic force between the ruler and the paper.
How a plastic ruler can become negativiely charged?
Technically, it doesn't. Static electricity is not something some things have or don't have. It is built up by two objects coming in contact with eachother. Some objects are more negative or positive than others, and the more positive items tend to lose their electrons more easily than the negatives, who tend to gain electrons. The gain/loss of electons happens on contact. Rubbing creates more contact, and therefore more gain/loss. The shock comes when a positively charged object touches a grounded item, such as a metal post or a person. Electrons jump to the object through the grounded item from the ground. If said object is a human, (s)he will feel a jolt of electricity, which we call static. Note: I call positive objects positive because they become positive on contact. I use the same reasoning with negative objects.
Why does plastic ruler that has been rubbed with cloth have the ability to pick up small pieces of paper Why is this difficult to do in humid day?
When a plastic ruler is rubbed with cloth, it becomes charged with static electricity. This static charge attracts small pieces of paper due to the phenomenon of electrostatic attraction. On a humid day, the moisture in the air can dissipate the static charge more quickly, making it harder for the ruler to pick up the paper.
Why ruler attracts your hair?
A ruler may attract your hair due to static electricity. When you rub a ruler against your hair, electrons transfer from one surface to the other, causing one to become positively charged and the other negatively charged. This attraction leads to your hair sticking to the ruler.
What attracts paper to a perspex ruler?
The attraction between the paper and the perspex ruler is due to static electricity. When the ruler is rubbed against the paper, electrons are transferred between the two materials, creating a temporary positive and negative charge that causes them to be attracted to each other.
Is a ruler a conductor of electricity?
Plastic is generally used as an insulator. A plastic ruler would not be a conductor of electricity.
What is the difference between static and dynamic electricity?
Electricity is a short term of electricity objects for example when we rub our comb or ruler to our hair some of the electrons move to the ruler and because of that it attracts pieces of paper Dynamic electricity is a flow of electrical energy that occurs in a long period time There are three variables to make sure that the dynamic electricity to flow: Voltage:is a term in electricity which represent electrical energy in electron.There are two sides of electricity.There are + and -,where + means the side that has no energy (0 energy) and the - side has the energy of electrons.Energy - attracts with + energy. Electrical current:The flow of electrical energy per second Resistance:The obstacle of energy flows.It is occurred on the cables and the electrical appliances
How do you separate salt and pepper that have got mixed in masala box using plastic ruler?
Provided all the spices in the masala box are very dry, you could place a static charge on the ruler by rubbing it against some wool, if you then pass it over the salt/pepper mixture, the pepper will jump up and stick to the ruler leaving the salt behind.
