yes
You can charge a balloon by rubbing it against a material that easily gives up electrons, such as wool or a polyester cloth. This process transfers electrons from the material to the balloon, giving it a negative charge.
it has a positive charge so the negative item attract to it if it is light enough
No, a balloon filled with static electricity will not stick to metal if rubbed against your head. The static charge on the balloon and your head would not be strong enough to hold the balloon to the metal.
When a charged balloon is brought close to a wall, the charges on the balloon induce an opposite charge on the wall due to electrostatic induction. This causes the wall to be attracted to the balloon. If the charges on the balloon are strong enough, the wall may even stick to the balloon momentarily.
No, the generator in a crank radio cannot produce enough power to charge a laptop.
A balloon sticks to the ceiling due to static electricity. When the balloon rubs against a surface, it gains a negative charge, which causes it to be attracted to positively charged surfaces like ceilings. This attraction is strong enough to overcome the force of gravity, making the balloon stick to the ceiling temporarily.
No, a mashed up fruit cannot blow up a balloon as fruits do not produce enough gas to inflate a balloon. Balloons are usually inflated with gases like helium or air pumped in using a pump.
You are most likely to build up enough static charge to see a shock when walking on carpets, rubbing a balloon against your hair, or shuffling your feet on a dry surface like carpet in winter.
Yes, they can, if law enforcement can produce enough evidence to support the charge, the proscutor CAN file that charge at his/her discretion.
When you rub a balloon against your hair, it becomes negatively charged due to the transfer of electrons. This negative charge creates an electrostatic force between the balloon and the wall, causing it to stick. The force between the negatively charged balloon and the neutrally charged wall is strong enough to counteract the force of gravity and keep the balloon from falling.
It probably would... If the metal wall area were small enough and not grounded. As the charged balloon touches the conductive metal wall, the wall quickly 'absorbs' and spreads the unbalanced charge throughout it's mass. (It only conducts away the charge from the part of the balloon touching the wall...) After dissipating the unbalanced charge from the balloon, there's no 'positive' / 'negative' charge separation to cause an attractive force so the balloon doesn't stick. In other words, the balloon looses part of its charge to the wall that has a much greater ability to store and spread electrical charges. Conductors, such as the metal wall, cannot be forced to maintain localized charge imbalances (like insulators can) as the imbalances are quickly conducted away. The electroscope experiment shows that conductors (small, ungrounded) CAN maintain net electrical charges (the foil leaves spread due to their holding like charges).
Yes, a balloon may be able to lift a book depending on the size and weight of the book in relation to the lifting capability of the balloon. The balloon would need to be large enough and filled with enough helium to counteract the weight of the book.
