Answer:
Explanation:
Given:
width of the wire, 
thickness of the flat wire, 
length of the wire, 
voltage across the wire, 
current through the wire, 
Now the net resistance of the wire:
using ohm's law
We have the relation between the resistivity and the resistance as:
where:
a = cross sectional area of the wire
resistivity of the wire material
B) <span> It is practical because a top-loading machine uses much more water than a front-loading machine.
Front-loading washing machines are able to better conserve water by automatically maintaining the same water level throughout the wash, while top-loading washing machines generally begin the cycle by filling up the barrel to a certain point. </span>
