Select the equation for density
Density = mass ÷ volume
Density = volume÷ mass
Density = mass x volume
The upthrust is equal to
The mass of displaced fluid
The weight of displaced fluid
The volume of displaced fluid
The weight of object
The mass of object
F=6πηrv is called
Stoke's Law
Hooke's Law
Newton's Law
Avogadro's Law
F=6πηrv is the formula for
drag force
upthrust
weight
friction
In the formula F=6πηrv, η stands for
viscosity
number of moles
number of molecules
runniness
temperature change
In the formula F=6πηrv, r stands for
Radius of object
viscosity
Diameter of object
Relative atomic mass
In the formula F=6πηrv, v stands for
speed
viscosity
volume
arbitrary value
Flow of fluids such that adjacent layers do not cross each other is called
turbulent
laminar
layered
smooth
Flow such that there are eddy currents etc.
Turbulent
Laminar
Layered
Smooth
For Stokes' Law to apply (select all that apply)
The object must be small
The object must be smooth
The object must be moving slowly
There must be laminar flow
The object must be spherical
A fluid which is very viscous is very
Runny like water
Gloopy like syrup
Dense like mercury
Low density like helium
Viscosity depends largely on
temperature
pressure
humidity
W is weight
F is drag
U is upthrust
For an object (e.g. a stone) falling at terminal velocity we say
W=F+U
W+F=U
W is weight
F is drag
U is upthrust
For an object (e.g. a bubble) rising at terminal velocity we say
W=F+U
W+F=U
