Question
1. A syringe has a plunger that has a radius of 0.5 cm. A 2 cm long needle is attached. The opening in this needle has a radius of 0.2 mm. The syringe is held horizontally, and a force is applied to the plunger. This force causes water to exit the end of the needle with a velocity of 100 cm/s. The water exiting the needle has a (gauge) pressure of 0. What is the force applied to the plunger?
a. 0.163 N
b. 0.280 N
c. 0.814 N
d. 0.757 N
e. 0.314 N
