Syringe Barrel A Syringe Has An Area Of 1.4 Cm2 At Its Barrel And Then Narrows Down To An Area Of 0.14 Mm2 At The Needle End.?

A syringe has an area of 1.4 cm2 at its barrel and then narrows down to an area of 0.14 mm2 at the needle end.? - syringe barrel

A syringe has an area of 1.4 cm2 in your race, then reduced to an area of 0.14 mm2 at the end of the needle. When a force of 5.4 N on the syringe, the force generated is applied to the tip of the needle?

I think the question is to describe the liquid in the syringe. This is the comparison between the fluid in the course of "vs. the liquid in the needle?" I have this problem in different ways, which a number of different answers, none of them properly. Could someone please help me with the steps? Real helpful answers will be greatly appreciated. Thank you all!

Force = Pressure * Area, and the pressure in the syringe and needle steady.
If a given force, a force of 5.4 N on a 1.4 cm ^ 2 surface later when the area is reduced to 0.14 mm ^ 2, is the force of 0.14 mm 2/1.4 inch, multiplied ^ ^ 2 = 0.001, for a force of 0.0054 N.
I think the most important source of confusion about the areas in cm ^ 2 to mm 2 ^ If you ever get a common unit, m ^ 2 is the thing easier.
1.4 cm ^ 2 = 1.4 * 0.01 ^ 2 = 1.4 * 0.0001 = 0.00014 m ^ 2
0.14 mm ^ 2 = 0.14 * 0,001 ^ 2 = 0.14 * 0.000001 = 0.00000014 m ^ 2
0.00000014
----------------- = 0.001
0.00014
