Answer:
1.28 m
Explanation:
Generally, pressure of fluid is given by
where g is acceleration due to gravity, h is the height and
is the density
Considering that the pressure for mercury is same as for blood only that the height and density of fluid are different then
Since g is constant, then
Making
the subject of the formula then

Where subscripts m and b denote mercury and blood respectively
Assuming density of blood is 1060 Kg/m3, density of mercury as 13600 Kg/m3 and substituting height of mercury for 0.1 m then

Answer:
6 light years = 57 million km
Explanation:
Given;
A light year = 9.5 million km
To calculate how far is 6 light years;
6 light years = 6 × 1 light year = 6 × 9.5 million km
6 light years = 57 million km
