Weight is directly related to mass, but it also
depends on the local gravity.
Acceleration is directly related to mass, but it also
depends on the net force acting on the mass.

depends on the density of the object or sample.
Inertia is directly related to mass, and is completely determined
by the mass. It doesn't depend on anything else, so this may be
the best choice.
Some guidance notes which may help.To calculate the current flow, Ohm's law can be used. This can be written as current=voltage/resistance, or I=V/R. V is 1.5V.R for the copper wire quoted would be calculated as R = resistivity x length/cross sectional area. The area would be calculated from the formula area = pi x diameter squared/4So, R=resistivity x length divided by (pi x diameter squared/4)Until is the resistivity of copper is known, that's about as far as can be gone.Any further questions, please ask.

harmed
so the relationship is Commensalism
