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
<span>The speed of a wave, V, is f *lambda. Where f is the frequency and lambda is the distance. If a new crest reaches the end every 4 secs; it takes 8s to cover the distance. Hence, f, which is the number of oscillations covered is 8s. So we have V = 8 * 5 = 40 ms^1.</span>
Answer:
a. petrification
Explanation:
tar seeps = natural trade that, because of its close proximity to the ground surface, seeps from the cracks in the Earth or between rocks forming pits or pools (tar pits)
amber = fossilized resin produced by extinct coniferous trees, typically yellow in color
mummification = a process in which the skin and flesh of a corpse can be preserved by embalming and drying
Answer:
The light bends away from the normal
Explanation:
We can solve the problem by using Snell's law:

where:
is the index of refraction of the first medium
is the index of refraction of the second medium
is the angle of incidence (angle between the incoming ray and the normal to the interface)
is the angle of refraction (angle between the outcoming ray and the normal to the interface)
We can rearrange the equation as

In this problem, light travels from an optically denser medium to an optically rarer medium, so

Therefore, the term
is greater than 1, so

which means that the angle of refraction is greater than the angle of incidence, and so the light will bend away from the normal.
