If a system undergoes a natural process it will go in the direction that causes the entropy of the system plus the environment to increase, this is another statement of
The potential difference across the conductors should be maintained constant by connecting the ends of wire to the terminal of a device called a source of
By which velocity a ball be projected vertically so that the distance covered by it in 5th seconds is twice the distance it covers in its 6th second ( g=10m/s2)
Two metal rods A and B have their initial lengths in the ratio 2 : 3 and coefficients of linear expansion in the ratio 4 : 3. When they are heated through same temperature difference the ratio of their linear expansion is
If a charged spherical conductor of radius 10 cm has potential V at a point distance 5 cm from its centre, then the potential at a point distance 15 cm from the centre will be
