An object is floating on water. Which of the following is true?

I. The object has a lower density than water

II. The buoyancy force would be higher if the object sank

III. The volume of fluid displaced would be higher if the object sank

According to Poiseuille’s principle, the flow rate __________ as viscosity increases and the flow rate __________ as length of pipe increases.

Fluid A and Fluid B flow through the same pipe. However, it is found that fluid A flows much slower than fluid B. What can you conclude about fluid A and fluid B?

One end of a pipe (End A) has twice the radius as the second end (End B). What can you conclude about the flow of fluid through this pipe?
