Calculate the equivalent resistance of circuit .

What is the formula?

What is meant by the statement" the melting poin of glycerine is 13 degree celsius

Consider an insulating crystal, made up of layers of atoms. what form would you expect the temperature dependence of the phonon heat capacity to approach at extremely low temperatures if the interlayer coupling is i)very strong (rigid coupling), and ii) very weak. explain.

The voltage applied across a given parallel-plate capacitor is doubled. how is the energy stored in the capacitor affected?
