The item with the most inertia is the one with the greatest mass.
It's easy to identify because it's also the heaviest one.
There are a great many other issues that make something
difficult for movers to move, besides its weight. Size, shape,
handles, wheels, getting it around tight corners, etc. So we
can't necessarily say that the heaviest item is the one that
presents the biggest problem for the movers.

Answer:
D. The object accelerates
Explanation:
Answer:
Explanation:
First of all, let's find the cross-sectional area of the copper wire. The radius of the wire half the diameter:
So the area is
Now we can calculate the resistance of the piece of copper wire between the bird's feet, with the formula:
where
is the resistivity of copper
is the length of the piece of wire
is the cross-sectional area
Substituting, we find
And since we know the current in the wire, I=149 A, we can now find the potential difference across the body of the bird, by using Ohm's law:
