  2. Impact pressure - Wikipedia

    en.wikipedia.org/wiki/Impact_pressure

    In compressible fluid dynamics, impact pressure (dynamic pressure) is the difference between total pressure (also known as pitot pressure or stagnation pressure) and static pressure. [ 1 ] [ 2 ] In aerodynamics notation, this quantity is denoted as q c {\displaystyle q_{c}} or Q c {\displaystyle Q_{c}} .

  3. Document-based question - Wikipedia

    en.wikipedia.org/wiki/Document-based_question

    In American Advanced Placement exams, a document-based question (DBQ), also known as data-based question, is an essay or series of short-answer questions that is constructed by students using one's own knowledge combined with support from several provided sources. Usually, it is employed on timed history tests.

    The AP U.S. History course is designed to provide the same level of content and instruction that students would face in a freshman-level college survey class. It generally uses a college-level textbook as the foundation for the course and covers nine periods of U.S. history, spanning from the pre-Columbian era to the present day.

    The Driver-Pressure-State-Impact-Response framework was developed by the European Environment Agency (EEA) in 1999. It was built upon several existing environmental reporting frameworks, like the Pressure-State-Response (PSR) framework developed by the Organization for Economic Co-operation and Development (OECD) in 1993, which itself was an extension of Rapport and Friend's Stress-Response ...

  8. Dynamic pressure - Wikipedia

    en.wikipedia.org/wiki/Dynamic_pressure

    Dynamic pressure is one of the terms of Bernoulli's equation, which can be derived from the conservation of energy for a fluid in motion. [1] At a stagnation point the dynamic pressure is equal to the difference between the stagnation pressure and the static pressure, so the dynamic pressure in a flow field can be measured at a stagnation point ...

    Globalization is the process of increasing interdependence and integration among the economies, markets, societies, and cultures of different countries worldwide. This is made possible by the reduction of barriers to international trade, the liberalization of capital movements, the development of transportation, and the advancement of information and communication technologies.
