  2. Basic State Exam - Wikipedia

    en.wikipedia.org/wiki/Basic_State_Exam

    In cases where an answer is illegible, incorrect, contains multiple symbols in one box, or a box is left empty, the student should leave the original response unchanged. Instead, they should record the correct answer in the section titled "Correction of Mistaken Answers for Tasks with Short Answers." In this section: Task numbers are not pre ...

  3. Box junction - Wikipedia

    en.wikipedia.org/wiki/Box_junction

    A box junction in London, pictured from atop the Monument in 1969. A box junction is a road traffic control measure designed to prevent congestion and gridlock at junctions.The surface of the junction is typically marked with a yellow criss-cross grid of diagonal painted lines (or only two lines crossing each other in the box), and vehicles may not enter the area so marked unless their exit ...

  4. Hume-Rothery rules - Wikipedia

    en.wikipedia.org/wiki/Hume-Rothery_rules

    Hume-Rothery rules, named after William Hume-Rothery, are a set of basic rules that describe the conditions under which an element could dissolve in a metal, forming a solid solution. There are two sets of rules; one refers to substitutional solid solutions, and the other refers to interstitial solid solutions.

  5. Science (UIL test) - Wikipedia

    en.wikipedia.org/wiki/Science_(UIL_test)

    The test for Grades 9-12 covers biology, chemistry, and physics, with 20 questions in each general field (though physics and chemistry often overlap). Each school may send up to four students for each junior high division. In order for a school to participate in team competition, the school must send three students.

  6. Kirchhoff's circuit laws - Wikipedia

    en.wikipedia.org/wiki/Kirchhoff's_circuit_laws

    The current entering any junction is equal to the current leaving that junction. i 2 + i 3 = i 1 + i 4. This law, also called Kirchhoff's first law, or Kirchhoff's junction rule, states that, for any node (junction) in an electrical circuit, the sum of currents flowing into that node is equal to the sum of currents flowing out of that node; or equivalently:

  7. Particle in a box - Wikipedia

    en.wikipedia.org/wiki/Particle_in_a_box

    Some trajectories of a particle in a box according to Newton's laws of classical mechanics (A), and according to the Schrödinger equation of quantum mechanics (B–F). In (B–F), the horizontal axis is position, and the vertical axis is the real part (blue) and imaginary part (red) of the wave function.

  8. FBI mnemonics - Wikipedia

    en.wikipedia.org/wiki/FBI_mnemonics

    The rules above are usually used to predict 'F' based upon 'B' and 'I' - the force on a moving charge when moving through a field, whether or not the charge is carried in a wire. However, this rule should not be confused with a different right hand grip rule for the prediction of the direction of a field ('B') produced by current ('I ...

  9. Matthias rules - Wikipedia

    en.wikipedia.org/wiki/Matthias_rules

    The Matthias rules are a set of guidelines to find low temperature superconductors but were never provided in list form by Matthias. A popular summarized version of these rules reads: [19] [20] [15] [8] High symmetry is good, cubic symmetry is the best. High density of electronic states is good. Stay away from oxygen. Stay away from magnetism
