3) ballon b will bulge more than balloon a because in container B it contains air so as air is present inside the container it will bulge and in CONTAINER A vaccum is present so as pressure is present inside it son deflate

Answer 2

2.

Let Time period of the oscillation = T

Time to travel between A to B = T/2
Time to travel between B to C = T/4

time taken in this motion between A to B to C = 3T/4 = 3

so, T = 4 sec ...

now time for 3.5 oscillation = 3.5 x 4 = 14 sec ..... ans...

(3.)
in container-B there will be pressure of air on the water surface but in container-A, vacuum doesn't have any pressure.

so, the pressure at the balloon in container-B will be more than in container-A..

change in pressure = pressure of air in container-B.

this is the extra pressure.

so, balloon in Container-B will expand more.
