In a given meter bridge, the current flowing through $$40 \Omega$$ resistor is

A body of mass $$0.04 \mathrm{~kg}$$ executes simple harmonic motion (SHM) about $$\mathrm{x}=0$$ under the influence of force $$\mathrm{F}$$ as shown in graph. The period of

A large number of water droplets each of radius '$$t$$' combine to form a large drop of Radius '$$R$$'. If the surface tension of water is '$$T$$' & mechanical equivalent of heat is '$$\mathrm{J}$$' then the rise in temperature due to this is

In resonance tube, first and second resonance are obtained at depths $$22.7 \mathrm{~cm}$$ and $$70.2 \mathrm{~cm}$$ respectively. The third resonance will be obtained at a depth
