Answer:
a
b
c
Explanation:
From the question we are told that
The Young modulus is
The length is
The area is
Generally the force acting on the tibia is mathematically represented as
derived from young modulus equation
Now this force can also be mathematically represented as
So
substituting values
Since the tibia support half the weight then the force experienced by the tibia is
From the above equation the extension (compression) is mathematically represented as
substituting values
From the above equation the maximum force is
I believe it’s OH have a good day
Answer: a. 667N
b. 665N
c. 54.5N
Explanation:
a) on the surface of the earth
W = mg
W = 68 × 9.81
= 667N
b) at the top of Everest (8848 m above sea level).
W =mg × R²/(R + H)²
W = 667 × [6378²/(6378 + 8.848)²
W = 665N
c) has 2 1/2 times the radius of the earth
W = mg × R²/(R + H)²
W = 667 × R²/(R + 2.5R)²
W = 54.5N
You can increase your flexibility by stretching with your muscles because when you stretch your muscles get stronger.

In the conservation of mass, mass is never created or destroyed in chemical reactions in the same way water is not created or destroyed it is only transferred from one form to another and its mass is always conserved.
