Answer: City site.
Explanation: The Andes Mountains extend eastward from Colombia across all of northern Venezuela to the island of Trinidad. The site of Caracas is a high rift valley within this system; hence, mountains enclose the city at all cardinal points.
Closing a straw's mouth with a finger traps air inside, creating lower pressure than the external atmospheric pressure. This pressure difference prevents water from spilling out by balancing the forces of gravity and atmospheric pressure, maintaining equilibrium within the straw.
When a straw's mouth is closed with a finger, a crucial principle of fluid dynamics comes into play: air pressure. Inside the straw, there is both water and air. Gravity tends to pull the water down, trying to empty the straw. However, when the mouth is closed, the air inside creates a barrier against the downward pull of gravity.
The pressure inside the straw is now lower than the atmospheric pressure outside. This atmospheric pressure pushes down on the water's surface outside the straw, effectively balancing the gravitational force trying to make the water spill out.
In simple terms, the combination of the finger closing the straw's mouth and the external atmospheric pressure prevents the water from spilling out. The pressure difference inside and outside the straw maintains equilibrium, counteracting the force of gravity.
In conclusion, closing the straw's mouth with a finger creates a pressure difference that prevents the water from spilling out due to the balance between atmospheric pressure and gravity.

Water does not spill out from a straw when its mouth is closed with a finger because the closed system created by the airtight seal prevents air from entering the straw. This allows the water to remain inside without spilling out.
When the mouth of a straw is closed with a finger, it creates an airtight seal. This seal prevents air from entering the straw and allows the water to remain inside without spilling out. The principle behind this is Pascal's law, which states that when pressure is applied to a fluid in a confined space, the pressure is transmitted equally in all directions.
In this case, when the finger closes the mouth of the straw, it creates a closed system. The pressure exerted by the finger on the mouth of the straw is transmitted through the water inside the straw, causing the water to push against the finger and maintain its position inside the straw.

Answer:
semantic
Explanation:
Semantic: The term "semantic" is described as one of the philosophical and linguistic study of certain meaning in semiotics, language, formal logics, and programming languages. Semantic is often being used in a few ordinary languages for referring a specific problem of "understanding" that generally comes down towards word connotation or selection.
In the question above, the given statement signifies the semantic understanding.
The given statement is True.
When possible, it is best to always travel with a cell phone.
Explanation:
Cell phone is a technology which has made possible to connect with people wherever they go. There is no need to have wires attached, which restrict people to connect with the people only at homes or other inside places. Cell phones allow people to talk to each other in every situation and wherever they go.
When people travel, it is very important to be connected with the family and the friends who care about them. Family need to know that the family member who is traveling is safe on the way, and for that it is important to be connected, and here Cell phones help.
There could be any emergency, where the person may need help, so if he is traveling with cell phone, he will be able to call who ever he wants.
