What are static charges?
The static charges are the charges that are developed on objects that are stationary. There are several ways by which static charges could be developed. One of the ways that static charges could be developed is by the use of friction. Friction is known to occur when surfaces are being rubbed together in such a way that there must have to be a transfer of charges.
Thus, in this case, we are told that Gillian gently rubs a rubber balloon on the fur of her pet cat. When she pulls the balloon away from the cat's fur, the fur is attracted to the balloon.
The reason why the fur becomes attracted to the balloon is that rubbing the balloon along the cat transfers extra electrons from the cat to the balloon.

What are forces of attraction?Forces of attraction is a force by which atoms in a molecule combine. it is basically an attractive force in nature. It can act between an ion and an atom as well.It varies for different states of matter that is solids, liquids and gases.
The forces of attraction are maximum in solids as the molecules present in solid are tightly held while it is minimum in gases as the molecules are far apart . The forces of attraction in liquids is intermediate of solids and gases.
The physical properties such as melting point, boiling point, density are all dependent on forces of attraction which exists in the substances.

Which type of data would be considered qualitative data? diameter measured distance travelled density calculated discoloration amount
Answers
Answer:
Explanation:
Qualitative data is descriptive information that cannot be measured in numbers. So among the choices, only discoloration amount is descriptive and cannot be measured.
The type of data which will be considered as qualitative data is discoloration amount.
What is qualitative data?Qualitative data is that data which depends on the quality not in the quantity of any object.
Diameter, travelled distance and density are the quantitative data means they all depends on the quantity and measurement. Whereas the discoloration amount is the qualitative data as it is not measurable and not depends on the quantity.
Hence correct answer is discoloration amount.

Explanation:
Why can't a volume of water be compressed or expanded like a volume of air in a closed syringe system?
Answers
Answer:
It is all about pressure. When you plug upon the nozzle, there is no way for the pressure of the fluid to rise above a certain value, so pushing in is opposed by the fluid pushing back on your finger, it gets hard! However, if you open the valve and allow fluid to squeeze out, then the pressure can be relieved a bit and that allows you to keep the piston moving down. That is applying an unbalanced force that allows the fluid to accelerate from zero velocity inside the barrel to some higher velocity through the nozzle.

(The picture shows a child sliding down a plastic slide.)
Which statement best describes why the child's hair stands up after he slides down the slide?
A) Friction caused a transfer of electrons between the slide and the child, making each of his like-charged hairs repel each other.
B) Energy was transferred from the slide to the child through induction, causing the child's hair to become charged and stand up.
C) Energy was transferred from the child to the slide through conduction, causing the child's hair to become charged and stand up.
D) Friction caused a transfer of electrons between the slide and the child, making his like-charged hairs attract the air through induction.
Answers
Answer:
Your answer is A: Friction caused a transfer of electrons between the slide and the child, making each of his like-charged hairs repel each other.
Explanation:
The most likely explanation for why the child's hair stands up after sliding down the slide is due to the transfer of electrons caused by friction between the slide and the child's hair. Hence, option A is correct.
Why does the child's hair stand up after sliding down the slide?When the child slides down the slide, there is friction between the slide and the child's hair. This friction causes a transfer of electrons between the two surfaces, with electrons moving from one surface to the other.
This transfer of electrons can result in the child's hair becoming negatively charged, which causes the individual hairs to repel each other, leading to the hair standing up.
Therefore, the correct answer is A Friction caused a transfer of electrons between the slide and the child, making each of his like-charged hairs repel each other.
