The resistance R of a wire is given by:
where
is the resistivity of the material
L is the length of the wire
A is the cross-sectional area of the wire.
For the wire in the problem, the resistivity is (copper resistivity)
. The length of the wire is L=1.3 m, while the cross-sectional area is
so the resistance of the wire is:
where
L is the length of the wire
A is the cross-sectional area of the wire.
For the wire in the problem, the resistivity is (copper resistivity)
so the resistance of the wire is:
Answer:
0
Explanation:
Since momentum is given by:
Therefore momentum is a vector quantity in the direction of velocity.
- Inelastic collision is the type of collision in which the masses combine after collision and start moving in the direction of the greater momentum but here in this case we have the momentum equal and opposite in direction.
<u>This case can be described mathematically as:</u>
since the mass and velocity are equal:
net momentum:
