1.	In a hypothetical arrangement two hollow glass balls are connected by a tube, which has a mercury pellet in the middle. If this arrangement is proposed to measure the 'temperature of the surroundings and act like a thermometer, then you propose to
Answer» Place the stationary tube horizontal and the marked readings can GIVE the required temperature. Place the stationary tube vertically under gravity and the marked readings can give the desired temperature. Place the tube stationary in horizontal position with RESPECT to a frame of reference UNIFORMLY ACCELERATING horizontally and the marked readings can give the desired temperature. Place the tube stationary in any position with respect to ground and the marked readings can give the desired temperature. Answer :B::C
