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:

Answer:
Explanation:
In order to convert the work function of cesium from electronvolts to Joules, we must use the following conversion factor:
In our problem, the work function of cesium is
so, we can convert it into Joules by using the following proportion:
