Answer: 4.74 mm
Explanation:
We can solve this problem with the following equation:
(1)
Where:
is the Young modulus for femur
is the stress (force 
applied per unit of transversal area 
) on the femur
Being:
the compression the femur can withstand before breaking
is the length of the femur without compression
Writing the data in equation (1):
(2)
(3)
Isolating :
(4)
(5) This is the compression in meters
Converting this result to millimeters:
The general accepted value of acceleration due to gravity, g, is 9.81 m/s^2.
That is an approximation because being the acceleration of gravity due to the attraction of the earth its magnitude will depend on the distance from the point to the center of the planet Earth.
The value of g is determined by using the Newton's Universal Law of gravity:
F = G * m of Earth * m of body / (distance^2)
Wehre {G* m of Earth / (distance^2) } = g
G is a universal constant = 6.67 * 10 ^ -11 N*m^2 / kg^2
m of Earth = 5.98 * 10 ^ 24 kg
distance = radius of Earth + height of the body
Given the the Earth is not a perfect sphere the radius varies. Also the height of the body varies.
If you take a mean radius of Earth of 6.37*10^6 m
you get
g = 6.67*10^-11 N*m^2/kg^2 * 5.98*10^24kg / (6.37*10^6 m)^2 = 9.83 m/s^2
Again, if you want a more precise value of g, you need to find the exact place where you are and then use the right r.
Mg + kx = QE , k = 2.4 x = 0.074-0.059 , Q = 6.6C m = given solve
Answer:21km
Explanation:13km+8km=21km
There isn't a whole lot of info here to go on, but if they are matching fossils from different spots on the globe, it would most likely be proof of supercontinents such as Pangea.
