Qualification rate. 87.33% (2023) Website. www.cbse.gov.in. The All India Senior School Certificate Examination (AISSCE) also called Class 12 Board Exams in common language, is the final examination conducted every year for high school students by the Central Board of Secondary Education on behalf of the Government of India.

The 2024 CBSE board examination for Class 10 were held from 15 February till 11 March and from 15 February till 2 April for class 12. The usual starting time for each exam was 10:30 am but depending on the length and/or maximum marks for the subject, the finishing time was either 12:30 pm (2 hours, shorter exams, usually 40-50 marks) or 1:30 pm ...

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.
t. e. Newton's law of universal gravitation states that every particle attracts every other particle in the universe with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between their centers. Separated objects attract and are attracted as if all their mass were concentrated ...
A neutrino (/ njuːˈtriːnoʊ / new-TREE-noh; denoted by the Greek letter ν) is an elementary particle that interacts via the weak interaction and gravity. [2][3] The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero. The rest mass of the neutrino is much ...
In physics, Hooke's law is an empirical law which states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, F s = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible deformation of the spring.
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. [1] Physics is one of the most fundamental scientific disciplines. [2] [3] [4] A scientist who specializes in the field of physics is called a physicist.
