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.

The answer is traditional education Philosophy. it alludes to a long back settled conventions that society usually used as a piece of schools. A couple of kinds of guidance change advance the gathering of dynamic preparing practices, an all the more comprehensive technique which bases on solitary understudies' needs and balance. As indicated by reformers, standard teacher focused systems focused on reiteration learning and recognition must be betrayed for understudy centered and undertaking based approaches to manage learning environment.
Mr. Selkie's classroom is a teacher-centered classroom, where he is the primary source of knowledge and authority. Students are relatively passive, primarily listening to his teaching. This is a traditional educational model and is part of how education fulfills its social control functions.
The type of classroom described, where students primarily listen to the teacher, who is the main source of knowledge and authority, is known as a teacher-centered classroom. In this type of classroom, the teachers serves as role models and leaders, and their authority is a way through which education fulfills its social control functions, this is part of the hidden curriculum present in educational institutions.
In this environment, the teacher holds the primary responsibility for imparting knowledge and guiding discussions. The students, while expected to participate when called upon, generally adopt a more passive role. They are mostly on the receiving end of the information.
This type of setting is in contrast to a student-centered classroom, where students take a more active role in their learning. The teacher's role in a student-centric classroom is that of a facilitator. However, in Mr. Selkie's situation, he is the primary source of instruction and knowledge. This model has its roots in traditional educational systems and is still prevalent in many classrooms today.

the closing of the Reading Railroad.
bank dividends came to an end for borrowers.
The closing of the reading railroad caused many banks that were investing in it to go bankrupt and then on a long chain of things that went horribly wrong to cause the HUGE panic of 1893. Pls mark branliest even though this is 3yrs late LOL.
