In 2013, NEET-UG was introduced, conducted by CBSE, replacing AIPMT. However, due to legal challenges, NEET was temporarily replaced by AIPMT in both 2014 and 2015. In 2016, NEET was reintroduced and conducted by CBSE. From 2019 onwards, the National Testing Agency (NTA) has been responsible for conducting the NEET exam.
Consequently, the object is in a state of static mechanical equilibrium. In classical mechanics, a particle is in mechanical equilibrium if the net force on that particle is zero. [1]: 39 By extension, a physical system made up of many parts is in mechanical equilibrium if the net force on each of its individual parts is zero. [1]: 45–46 [2]
Since the starting of the examination in 1961, the syllabus majorly consists of topics that are taught in Indian High schools, from the curriculum of Class XI and Class XII. These include topics from mathematics, physics and chemistry (organic chemistry, inorganic chemistry and physical chemistry). A recent change in the syllabus was carried ...
Equilibrant force. In mechanics, an equilibrant force is a force which brings a body into mechanical equilibrium. [1] According to Newton's second law, a body has zero acceleration when the vector sum of all the forces acting upon it is zero:
The proportionality constant was called an affinity constant, k. The equilibrium condition for an "ideal" reaction was thus given the simplified form [] [] = ′ [′] [′] [A] eq, [B] eq etc. are the active masses at equilibrium. In terms of the initial amounts reagents p,q etc. this becomes
Classical thermodynamics deals with states of dynamic equilibrium.The state of a system at thermodynamic equilibrium is the one for which some thermodynamic potential is minimized (in the absence of an applied voltage), [2] or for which the entropy (S) is maximized, for specified conditions.
In physics, the Saha ionization equation is an expression that relates the ionization state of a gas in thermal equilibrium to the temperature and pressure. [1] [2] The equation is a result of combining ideas of quantum mechanics and statistical mechanics and is used to explain the spectral classification of stars.
In physics and thermodynamics, the ergodic hypothesis [1] says that, over long periods of time, the time spent by a system in some region of the phase space of microstates with the same energy is proportional to the volume of this region, i.e., that all accessible microstates are equiprobable over a long period of time.
