CUET PG 2024 Question Paper Physics Shift-2 (14th March)
For the following questions answer them individually
Which of the following are correct statements about logic gates and their combinations:
(A). The output of an EX-OR gate is a logic '1' when the inputs are unlike and a logic '0' when the inputs are like.
(B). The output of a NAND gate is a logic '1' when all its inputs are a logic '1'.
(C). The output of a two-input EX-NOR gate is a logic 'l' when the inputs are like and a logic '0' when they are unlike
(D). The shorting the inputs of a NOR gate gives a NOT circuit.
Choose the correct answer from the options given below:
Let's consider nitrogen gas obeys the Van der Waals equation of state with best fit value of the parameters $$a = 0.14Pa.m^{6} / mol^{2}$$ and $$b = 39.0 cm^{3} / mol$$ Estimate approximate diameter of the nitrogen gas molecules. Assume each molecule is a
sphere.
A system consists of two phases maintained at constant temperature (T) and pressure (p). The number of moles present in phase 1 and phase 2 of the system is represented by n i (where i = 1,2) and Gibbs free energy per mole of phase i at this temperature and pressure is $$g_{i}$$ (T,p). The necessary condition for equilibrium:
Choose the incorrect statements:
(A). A particle can travel in free space faster than the velocity of light in free space.
(B). A particle can travel in a material medium faster than the velocity of light in free space.
(C). A particle can not travel in the material medium.
(D). The velocity of light in free space is an absolute constant.
Choose the correct answer from the options given below:
Select the correct alternative (s): The heavier of the two particles has smaller de-Broglie wavelength when both of them:
(A). move with same velocity
(B). move with same momentum
(C). move with same kinetic energy
(D). fall through same height
Match List-I with List-II
Internal energy (U), Specific heats ($$C_{v}, C_{p}$$), Enthalpy (H). Helmholtz free energy (F) and Gibbs free energy (G) are the thermodynamic variables.
