Jeff's body contains about 5.31 L of blood that has a density of 1060 kg/m3. Approximately 45.0% (by mass) of the blood is cells and the rest is plasma. The density of blood cells is approximately 1125 kg/m3, and about 1% of the cells are white blood cells, the rest being red blood cells. The red blood cells are about 7.50µm across (modeled as spheres). What is the mass of the blood mblood in Jeff's body?

The mass of the blood is 5.6286 kg

Explanation:

Given:

V = volume of blood = 5.31 L = 0.00531 m³

ρ = density = 1060 kg/m³

Question: What is the mass of the blood mblood in Jeff's body, m = ?

To calculate the mass of the blood you just have to multiply the density of the blood by the volume occupied by it:

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
