uming cylindrical symmetry, you can find the change in volume of the arm, which gives an indication of blood flow. Take

\\\ ho _(Hg)=9.4\\\\times 10^(-7)\\\\Omega =m

.\ (a) Calculate the resistance of the mercury.\

\ (b) Calculate the fractional change in resistance during the heartbeat. Hint: Because the cylindrical volume is constant,

V=A_(i)L_(i)=A_(f)L_(r)

and

A_(f)=A_(j)(L_(i)L_(r))
