use the drop - down menus to complete the sentences. a thin wire has resistance than a thick wire. a short wire has resistance than a long wire. a warm wire has resistance than a cool wire.

Answer

Explanation:

Step1: Recall resistance - cross - section relationship

Resistance $R$ is inversely proportional to the cross - sectional area $A$ of the wire, i.e., $R=\rho\frac{l}{A}$, where $\rho$ is the resistivity of the material and $l$ is the length of the wire. A thin wire has a smaller cross - sectional area. So, a thin wire has more resistance than a thick wire.

Step2: Recall resistance - length relationship

Resistance $R$ is directly proportional to the length $l$ of the wire ($R = \rho\frac{l}{A}$). So, a short wire has less resistance than a long wire.

Step3: Recall resistance - temperature relationship

For most materials, resistance increases with an increase in temperature. So, a warm wire has more resistance than a cool wire.

Answer:

A thin wire has more resistance than a thick wire. A short wire has less resistance than a long wire. A warm wire has more resistance than a cool wire.
