On 12 April 2018, the police said that Rakesh Kumar, who leaked the class 12 economics paper, had leaked class 10 mathematics paper also. [40] Consequently, the Central Board of Secondary Education has put in place a system of "encrypted" question papers, which are supposed to be printed by the schools half an hour before the exam starts. [41]
Just as the class P is defined in terms of polynomial running time, the class EXPTIME is the set of all decision problems that have exponential running time. In other words, any problem in EXPTIME is solvable by a deterministic Turing machine in O (2 p ( n ) ) time, where p ( n ) is a polynomial function of n .
Unacademy is an Indian multinational educational technology company that provides online educational platform [2] with its headquarters in Bangalore.It prepares students for various competitive exams (like JEE, NEET, UPSC, Chartered Accountancy, GATE, UPSC NDA, CUET, Boards etc.), as well as provides content on foundational and skill building courses (programming, photography, entrepreneurship ...
It is common to use idealized models in physics to simplify things. Massless ropes, point particles, ideal gases and the particle in a box are among the many simplified models used in physics. The laws of physics are represented with simple equations such as Newton's laws, Maxwell's equations and the Schrödinger equation. These laws are a ...
These electives are pure sciences (Physics, Chemistry, Biology), mathematics (Physics, Chemistry, Maths), and computer science (Physics, Chemistry, Computer Science). STEM subjects are also offered as electives taken in the 11th and 12th grades, more commonly referred to as first and second year, culminating in Intermediate exams.
M-theory is a theory in physics that unifies all consistent versions of superstring theory. Edward Witten first conjectured the existence of such a theory at a string theory conference at the University of Southern California in 1995.
Groups of students undertaking project-based learning. Project-based learning is a teaching method that involves a dynamic classroom approach in which it is believed that students acquire a deeper knowledge through active exploration of real-world challenges and problems. [1]
In nuclear physics, area cross-sections (e.g. σ in barns or units of 10 −24 cm 2), density mean free path (e.g. τ in grams/cm 2), and its reciprocal the mass attenuation coefficient (e.g. in cm 2 /gram) or area per nucleon are all popular, while in electron microscopy the inelastic mean free path [14] (e.g. λ in nanometers) is often ...
