When we press the bulb of a dropper
, with its nozzle kept under water, air in
the dropper is seen to escape in the form of bubbles. If we then release the
pressure on the bulb, water gets filled in the dropper. The rise of water in the
dropper is due to-????
a) pressure of water in the container
b) weight of the bulb
c) gravity of the earth
d) atmospheric pressure

Answer:
when we put anything just directly inside the water first of all two things take it up try to take it up it on the water surface number one is by beyond force and number to his the air present inside the object ok...
and weight of the bulb will be if the bulb denser than the water level means density and the water then it will definitely at any period of time it will definitely go in water and if it is lighter than water then we will try so much then also it can't able to go in the water
3.where we put to the something inside the water the gravity inside the water became less as because of buayant force..
and up to now I don't have much more knowledge about the atmospheric pressure... so I am sorry I can't able to explain you what is the role of atmospheric pressure in this experiment..
if you like him then make me brainiest I request you
