A syringe has an area of 4 cm2 in the barrel of the syringe and then narrows down to an area of 0.1 mm2 at the needle end. If a force of 9 N is applied to the syringe, what is the force produced at the tip of the needle?

Please help!

Did you know?

Did you know that the area of a syringe can affect the force produced at the tip of the needle? In this case, the syringe barrel has an area of 4 cm2, while the needle end narrows down to an area of 0.1 mm2. When a force of 9 N is applied to the syringe, the force produced at the tip of the needle can be calculated using the principle of Pascal's law, which states that pressure exerted on an enclosed fluid is transmitted equally in all directions. By comparing the areas, we can determine that the force produced at the tip of the needle will be significantly higher than the applied force of 9 N due to the smaller area. This understanding is essential in medical settings where syringes are used for administering medication or drawing blood.
