Two closed containers look the same but when is packed with led and the other with a few feathers how could you determine which has more mass if you end the containers were orbiting in a weightless condition in outer space

You would want to push both containers, first one and then the other,
with exactly the same strength of push. 

The one that takes off slower (with less acceleration from the same
net force) is the one with more mass.

This is what i found “in a gas turbine engine, the combustor or combustion chamber is fed high pressure air by the compression system. early gas turbine engines used a single chamber known as a can type combustor. today three main configurations exist: can, annular and cannular (also referred to as can-annular tubo-annular).” i hope this you for what your looking for. can you plz mark me brainliest?
