Match List I with List II:
Choose the option with all correct matches.
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
A sphere of radius R is cut from a larger solid sphere of radius 2R as shown in the figure. The ratio of the moment of inertia of the smaller sphere to that of the rest part of the sphere about the Y-axis is :
The output (Y) of the given logic implementation is similar to the output of an/a …………. gate.
Given below are two statements:Statement I: In a floral formula, \(\oplus\) stands for zygomorphic nature of the flower, and \( G \) stands for the interior ovary. Statement II: In a floral formula, \(\oplus\) stands for actinomorphic nature of the flower, and \( G \) stands for the superior ovary.In light of the above statements, choose the correct answer from the options given below:
Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)
In an oscillating spring mass system, a spring is connected to a box filled with sand. As the box oscillates, sand leaks slowly out of the box vertically so that the average frequency ω(t) and average amplitude A(t) of the system change with time t. Which one of the following options schematically depicts these changes correctly?
Identify the correct orders against the property mentioned:A. H$_2$O $>$ NH$_3$ $>$ CHCl$_3$ - dipole moment B. XeF$_4$ $>$ XeO$_3$ $>$ XeF$_2$ - number of lone pairs on central atom C. O–H $>$ C–H $>$ N–O - bond length D. N$_2$>O$_2$>H$_2$ - bond enthalpy Choose the correct answer from the options given below:
Three identical heat conducting rods are connected in series as shown in the figure. The rods on the sides have thermal conductivity 2K while that in the middle has thermal conductivity K. The left end of the combination is maintained at temperature 3T and the right end at T. The rods are thermally insulated from outside. In steady state, temperature at the left junction is \(T_1\) and that at the right junction is \(T_2\). The ratio \(T_1 / T_2\) is
AB is a part of an electrical circuit (see figure). The potential difference \(V_A - V_B\), at the instant when current \(i = 2\) A and is increasing at a rate of 1 amp/second is:
Given below are two statements:Statement I: The primary source of energy in an ecosystem is solar energy. Statement II: The rate of production of organic matter during photosynthesis in an ecosystem is called net primary productivity (NPP).In light of the above statements, choose the most appropriate answer from the options given below:
