A student stands at the edge of a cliff and throws a stone horizontally over the edge with a speed of v0 = 15.0 m/s. The cliff i
s h = 49.0 m above a flat, horizontal beach as shown in the figure. (a) What are the coordinates of the initial position of the stone? x0 = m y0 = m (b) What are the components of the initial velocity? v0x = m/s v0y = m/s (c) Write the equations for the x- and y-components of the velocity of the stone with time. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not include units in your answer.) vx = vy = (d) Write the equations for the position of the stone with time, using the coordinates in the figure. (Use the following as necessary: t. Let the variable t be measured in seconds. Do not state units in your answer.) x = y = (e) How long after being released does the stone strike the beach below the cliff? s (f) With what speed and angle of impact does the stone land? vf = m/s ? =

Answer:
a
The mass of blood is
b
The number of blood cells is
Explanation:
From the question we are told that
The volume of blood is
The density of the blood is
% of blood that is cell is = 45.0%
% of the blood that is plasma is = 55.0%
density of blood cell is
% of cell that are white is = 1%
% of cell that is red is = 99%
The diameter of the red blood cell is =
The radius of the red blood cell is
Generally the mass is mathematically represented as
Substituting value
Mass of cell is = 45% of m
= 0.45 * 5,7876
= 2.60442 kg
The volume of cells is =
The volume of white blood cell is = 1% of volume of cells
The volume of a single cell is
The volume of red blood cells is
The number of red blood cell is
The Number of white blood cell is
The total number of blood cells is
