Two closed containers look the same but one is packed with lead and one with a few feathers How could you determine which has more mass if yo and the containers were orbiting in a weightless condition?

I know this answer is basic, but it has been over 40 years since I took a Physics course. Although you cannot feel any weight while holding them in zero gravity, there is a way to determine which is which. Due to the rule [which I cannot recall in order to recite] regarding inertia [an object not in motion will tend to resist movement] when you hold each container firmly, and attempt to rapidly move them, the container with the greater mass [the lead] will offer greater resistance to acceleration of movement, and the container with the feathers can be accelerated much more easily.

How does a pound of bricks and a pound of feathers compare?
-- The bricks and the feathers have the same weight.-- The bricks and the feathers have the same mass.-- The feathers have more volume than the bricks.-- The bricks have more density than the feathers.-- Neither the package of bricks nor the package of feathers is edible.-- The bricks definitely sink in water, whereas the feathers may float on water.-- When dropped through air, the feathers fall slower than the bricks, because of air resistance.-- I'm guessing that the feathers cost more than the bricks.
How do feathers help birds fly?
The flight feathers are the feathers located on the wings and tail. There are primary flight feathers that on the bird would be equivalent to our hand. A bird also has secondary flight feathers which when comparing to a human would be our forearm. If you unfold the wing of a bird you will see the flight feathers.

The feathers "take up more room" than the lead. It would be hard to compress the feathers to make them as dense as lead. The feathers have more volume.

What is an adaptation of feathers to meet its function?

What are are three adaptations that enable birds to fly?
Hollow bones, curved wings to make them aerodynamic and light feathers to make them almost weightless.
Bird feathers repel water?

Males are usually brighter colored.
What do birds do to keep their feathers in good condition for flying?
They bathe a and preen themselves.
What is the best way to determine the phenotype of the feathers on a bird?
Analyze the birds genes
Roosters have genes that determine feather length Which term describes the form of a gene that produces a specific trait such as long feathers or short feathers?
Allele is the term that describes the form of a gene that produces a specific trait such as long feathers or short feathers. Traits are passed in discrete units from parents to there offspring.
What kind of bird looses their feathers and why?
Disease - birds do not normally loose their feathers. When they change them it is called moult.Moulting is a process (like shedding in mammals) done regularly by birds, to replace old feathers with new, healthy feathers. This is normal. When a bird loses many feathers at once, it is usually due to the bird plucking out its own feathers OR a condition called French Moult, for which there is no cure.All birds may or may not lose their feathers. It is only when this happens to them and or they die.
