Answer:
C. Chemoautotroph
Explanation:
The new bacterium are able to create their own energy and biological materials (glucose) from inorganic chemicals (CO2 and H2), therefore they are called chemoautotroph.
Explanation:
The given data is as follows.
= 89 MPa,
= 336 MPa
Y = 0.92
Now, we will calculate the length of critical interior flaw as follows.

= 
=
= 209.04 mm
Thus, we can conclude that minimum length of a surface crack that will lead to fracture is 209.04 mm.
Newton’s third law states that when two bodies interact, they apply forces to one another that are equal in magnitude and opposite in direction. The third law is also known as the law of action and reaction. Hope this helps.
