1: A hypodermic syringe contains a medicine with the density of water. The barrel of the syringe has a cross-sectional area (2.50x105) m², and the needle has a cross-sectional area (1.00x10 8) m². In the absence of a force on the plunger, the pressure everywhere is 1.00 atm. A force F of magnitude 2.00 N acts on the plunger, making medicine squirt horizontally from the needle. Determine the speed of the medicine as it leaves the needles tip.

Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.
