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
