Why does a straw attract another straw when rubbed with piece of paper but repels it if it is rubbed with a sheet of paper?
When a straw is rubbed with a piece of paper, it acquires a positive charge due to the transfer of electrons from the paper. Two positively charged straws will repel each other. However, when a straw is rubbed with a sheet of paper, it acquires a negative charge, and opposite charges attract, resulting in the straws being attracted to each other.
What happens when a straw is rubbed with a sheet of paper?
When a straw is rubbed with a sheet of paper, friction causes electrons to transfer between the two materials. The straw becomes negatively charged as it gains electrons, while the paper becomes positively charged as it loses electrons. This can result in the two objects attracting or repelling each other.
What happens when a straw is rubbed with your body?
Rubbing a straw against your body transfers electrons from your body to the straw, giving the straw a net negative charge due to an excess of electrons. This charge imbalance can cause the straw to attract lightweight objects like small pieces of paper or dust.
Why does a straw appear to be bent when placed in a glass of water?
When light travels from one medium to another, such as from air to water, it can change direction. This change in direction is called refraction. As light passes through the water and into the air inside the straw, it refracts again, causing the straw to appear bent at the water's surface.
What forces the liquid upward in a straw?
The pressure difference between the atmosphere and inside the straw causes the liquid to be pushed upward. When you create a low pressure by sucking on the straw, the higher air pressure outside the straw pushes the liquid up to equalize the pressure difference.

Why a straw rubbed with a paper attracts another straw?
When straw is rubbed with paper it acquires charge due to friction. This straw when brought near uncharged straw induces opposite charge in the region of the uncharged straw nearer 2 the charged one. Then as the law is, unlike charges attract.
What happens when a straw is rubbed with a sheet of paper?

Why is salt and pepper attracted to a straw after its been rubbed on felt or wool?
Both the salt and the pepper are attracted to the straw because of electrical charges. When you rub the straw on the wool/felt, those electrical charges are created.
