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:

Answer:
Elastic Collision
Inelastic Collision
The total kinetic energy is conserved. The total kinetic energy of the bodies at the beginning and the end of the collision is different.
Momentum does not change. Momentum changes.
No conversion of energy takes place. Kinetic energy is changed into other energy such as sound or heat energy.
Highly unlikely in the real world as there is almost always a change in energy. This is the normal form of collision in the real world.
An example of this can be swinging balls or a spacecraft flying near a planet but not getting affected by its gravity in the end.
