Alength of #8 copper wire (radius = 1.63 mm) has a mass of 24.0 kg and a resistance of 2.061 ohm per km. what is the over all resistance of the wire?

Answer : The overall resistance of the wire is

Explanation :

First we have to determine the volume of copper wire.

Density of copper wire =

Now we have to determine the area.

where,

r = radius of copper wire = 1.63 mm

Now we have to determine the length of the wire.

conversion used :

Now we have to determine the overall resistance of the wire.

Therefore, the overall resistance of the wire is

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
