Question

please answer this question. it's very urgent for me ​

Answer 1

Answer:

a) 1st one is moving freely inward and 2nd one is want some more time than first and 3rd one wants more time than others to move inward

b)here three syringes have time differences for moving inward because of friction of the objectives in side of syringe

Answer 2

Answer:

observation: it takes very less effort in pushing the piston of the first syringe, comparatively more in the second one,and a lot more in the third one

Conclusion:the density(mass per unit volume)

of substances increases as we move from syringe one to syringe three,hence more force needs to be exerted to cause equal displacement of the pistons.

I hope this helps you friend
