An experiment is conducted to determine the resistance of an unknown resistor using a meter bridge. The known resistance is
, and the length of the bridge wire is
. When the jockey is slid along the bridge wire, the balance point is found at a distance
from the end connected to the known resistance. Calculate the resistance of the unknown resistor.
5 g of Na2SO4 was dissolved in x g of H2O. The change in freezing point was found to be 3.820C. If Na2SO4 is 81.5% ionised, the value of x (K
A capacitor is made of two square plates each of side 'a' making a very small angle
A solution of m-chloroaniline, m-chlorophenol and m-chlorobenzoic acid in ethyl acetate was extracted initially with a saturated solution of NaHCO3 to give fraction A. The leftover organic phase was extracted with d
