Sometimes clothes removed from the dryer cling together. What kinds of charges are on the clothes ?
Answers
The answer is "opposite charges."
Final answer:
When clothes are removed from the dryer and cling together, it is because static electricity is created from the clothes rubbing together in the dryer. This results in an imbalance of electrical charge on the clothes, with some having a net positive charge and others a net negative charge, which makes them attract and stick to each other.
Explanation:
When clothes are removed from the dryer and they cling together, this is due to the presence of static electricity. Static electricity occurs when materials are rubbed together, causing an exchange of electrons. This exchange results in the materials being electrically charged. In the case of your dryer, the process of tumbling and rubbing the clothes together can strip electrons from the clothes and deposit them on other pieces.
This creates an imbalance in charge, leading to some clothes having a net positive charge and others with a net negative charge. The positively charged clothes are attracted to the negatively charged ones, and this attraction causes the clothes to stick together. The force that brings these different charged clothes together is called electrostatic force. If the clothes are damp, the presence of water molecules can suppress the charge, reducing the static cling.

The tying results in the more visible veins of upper arms due to blood flow restriction.
Veins are the part of circulatory system in the body, that functions to carry deoxygenated blood from different parts of the body to the heart.
The venipuncture has been the process of insertion of drugs or chemicals in a body through vein. The veins of the upper arm has been tied to make them more visible.
The upper arm veins are more visible as there has been blood flow restriction in the veins by tying that results in the bulging out of the vein.

C. 217.8 g
Explanation:
First, we find the weight of KF. notice they are 1:1 ratio. so the molar mass of K is 39.0983 and Fluorine is 18.998403
we add them together we get 58.09 g/mol
now to find the mass we do
* 3.175 mol
mol and mol cancel out, we left with 58.096 grams * 3.75
if you multiply you get 217.86 grams.

Answers
Answer:
Option A. Dense water floats.
Explanation:
Ocean circulation act as conveyor belt which transport warm water from the tropics towards poles from where cold water sinks to the deep ocean. It is also known as the thermohaline circulation because it is driven by salinity and temperature.
However, change in climate causing these ocean's thermohaline current to slow down because influx of cold and melting fresh water from the polar region is disrupting these circulation as influx of fresh water making the water less saline and less dense and hence it become harder to sink to deep ocean.
Answer:
C. Increase in temperature - Ice melts and freshens water - Freshwater floats over denser salty water
