A galvanometer together with an unknown resistance in series is linked across two identical batteries each of 1.5V. whenthese batteries are connected in series the galvanometer records a current of 1A and when the batteries are in parallel the current is 0.6A. The internal resistance of battery will be ?
Ans) R(net) in first case= R+2r
V=3V,
I=1=V/R=>R+2r=3.......eq(1)
R(net) in Second case= R + r/2
V=1.5V
I=V/R=>.6=3/2R+r
=> 5=2R+r..............eq(2)
Solving eq1 and eq2
we get r= 1/3 or .33 ohms.

Vibratory and Oscillatory Motion : To and fro or back and forth motion of an object is known as vibratory and oscillatory motion.
Explain the Adding Waves? When two waves come from the same light source, the light waves are coherent, meaning that the phase difference between the waves is constant in time.
