When removing a load of clothes from her clothes dryer, Tia noticed that all her sweaters were stuck together. She concluded that this was an example ofastatic electricity produced by like charges bstatic electricity produced by unlike chargesccurrent electricity produced by neutral objects dcurrent electricity produced by the conducting clothes

A polythene ruler and a cotton cloth are electrically neutral.  When the ruler is rubbed with the cloth, the ruler becomes negatively charged.  Why does this happen?Protons (positive charges) are transferred from the ruler to the clothElectrons (negative charges) are transferred from the ruler to the clothProtons (positive charges) are transferred from the cloth to the rulerElectrons (negative charges) are transferred from the cloth to the ruler2Which of the following is NOT due to static electricity?A lightning strikeA bulb lighting up when connected to an electric circuitA balloon being attracted to a wallA ruler being used to pick up pieces of paper3When a positively charged rubber balloon is placed in contact with a neutral wall, it appears to ‘stick’ to the wall.  Which of the following best explains why this happens?Electrons (negative charges) in the wall are attracted towards the balloonProtons (positive charges) in the wall are repelled away from the balloonProtons (positive charges) in the wall are attracted towards the balloonElectrons (negative charges) in the wall are repelled away from the balloon4Which of the following CANNOT be easily be charged by friction?A piece of paperA sheet of aluminium foilThe rubber sole of a shoeSome plastic cling film5Which of the following atoms is NOT electrically neutral?One which contains 2 protons, 2 neutrons and 1 electronOne which contains 2 protons, 2 neutrons and 2 electronsOne which contains 1 proton and 1 electronOne which contains 3 protons, 4 neutrons and 3 electrons

Static dissipative materialsSelect one:a. Dissipate humidity in the work areab. Conduct electricity slowly not to cause shock hazard and injury to a personc. Prevent electricity from be conducted. Ground electricity to make charges harmless

Select all of the options that correctly complete the sentence.After rubbing the balloon against the sweater, the balloon:was attracted to an object with positive chargerepelled an object with positive chargehad lots of extra electronsrepelled electrons in the wall

Based on your experiments with the Balloons and Static Electricity simulation (PhET), complete the following sentences:Once the balloon has acquired the charge, it is attracted to the when placed in the space between the sweater and wall. When the balloon is placed in contact with the wall,

Choose the correct text in the piece.Which sentence from the piece shows the effect of a person touching something that carries electricity?from Electricity for the 4-H Scientistby Eric B. WilsonElectrical Conductors     Even if you're never going to repair a lamp or make a chick brooder, you should know about conductors and insulators. This is because you happen to be a fairly good conductor of electricity. Electricity will pass easily through you to other conductors—the ground, for instance.When this happens you may get a shock, burn, or serious injury.But it doesn't ever have to happen, if you learn to understand your friend, electricity.     Silver, copper, iron, aluminum and many other metals are very good conductors. Water, acids, and salts are too.Electricity passes over or through them very easily.Like water pipes, the larger the conductor, the more electricity it can carry. When conductors are too small for the amount of electrons trying to move over them, they get hot, melt, or may start fires. That's why wire size is important.Electrical Insulators     Insulators are the opposite of conductors. Electricity has trouble passing through some materials. Rubber, most plastics, dry wood, oils, and glass are some of the good insulators. It's the amount and kind of insulation that counts.If it has enough force, electricity can pass through just about anything—even jump gaps!     Electricity, like water, flows along the easiest paths. It is always trying to get to the ground. The earth attracts it. It stays on the wires unless a person, a wet branch, or some other conductor gives it a path to the ground.Do not touch any wire which might be carrying electricity.
