the circumference =the actual length of the wire
same material and Same thickness so we can now apply unitary method
for l=2*pie*r
as length and resistance are directly proportional
we get
when length =2*pie*r,resistance is 10ohm
so for 1 unit length, resistance =10/2*pie*r
for the diameter(2r),
resistance =10*2r/2*22/7*r)
=10/(22/7)=10*7/22=70/22=3.18ohm
hope it is helpful

Answer:
They are
small carbohydrates which are formed
by condensation (a chemical reaction in
which two molecules combine to form
one molecule with loss of a small
molecule usually water) of 2-9
monosaccharides units are joined
together b glycosidic bond.
Depending upon the number of
monosaccharide molecules condensed to
form oligosaccharides, they can be:
Disaccharides (e.g. sucrose, maltose,
lactose, trehalose (present in
haemolymph of insects),
Trisaccharides(e.g. raffinose – made up
of glucose, fructose and galactose),
Tetrasaccharides (e.g. stachyose) et
