i am very poor in this electric circuits consisting resistances, capacitors and both.which books do u guys prefer me or wat should i do to master this topic?
how do u relate linear and angular accelerations of 2 or more bodies of a system in various cases?
try d.c.pandey as well.it has many good problems.
A spherical ball A of surface area 20 is kept at the cantre of a hollow spherical shell B of area . The surface of A & the inner surface of B emit as blackbodies. assume that the thermal conductivity of B IS POOR & that of A is high & there is vacuum between A&B. the heat capacities of A & B are 42J per *C & 82J per*C. Initially the temp of A is 100*C & that of B is 20*C. find the rate of change of temp of A & that of B @ this instant.
a calorimeter contains 50g of water at 50*c. the temp falls to 45*c in 10 minutes. when the calorimetr contains 100g of water at 50*c, it takes 18 mins for the temp 2 bcum 45*c. find the water equivalent of the calorimeter. ( ANS:12.5G )
