Explanation:
The resistance of a wire is given by :
Where
is the resistivity of the wire
l = initial length of the wire
A = initial area of cross section
If length and the area of cross section of the wire is doubled then new length is l' and A', l' = 2 l and A' = 2 A
So, new resistance of the wire is given by :
R' = R
So, the resistance of the wire remains the same on doubling the length and the area of wire.
Answer:
Explanation:
Given:
cross sectional area of the bone,
factor of up-scaling the dimensions,
Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.
The scaled up area is:
