Question

A veterinarian injects medicine from a syringe into a dog's leg. The dog's diastolic blood pressure is 80 mmHg. The syringe barrel has a cross-sectional area of 2.0 x $$10^{-6}$$ $$m^{2}$$, the syringe plunger has a cross-sectional area of 2.3 x $$10^{-6}$$ $$m^{2,}$$ and the needle has a cross-sectional area of 3.0 x $$10^{-8}$$ $$m^{2}. $$Determine the minimum force the veterinarian must apply with their thumb on the plunger to inject the medicine.
