Explanation:
if u look at the back of ur car when its on u can feel the heat from the exhaust and whT ur feeling is the heat coming from the carbon monoxide gases
Answer:
275 MPa
Explanation:
Regardless of what it is holding, the stiffness of a bolt depends on its own material properties and geometry.
The stiffness is:
![k = E * \frac{A}{l}](https://tex.z-dn.net/?f=k%20%3D%20E%20%2A%20%5Cfrac%7BA%7D%7Bl%7D)
I assume this one is made of steel, because regular bolts are steel.
The Young's modulus for steel is E = 210 GPa
The longitude is given. (But note that in a real application you have to consider the length up to the nut.)
The section is (using the nominal diameter of 10 mm)
![A = \frac{\pi * d^2}{4} = \frac{\pi * 0.01^2}{4} = 7.85e-5 m^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cfrac%7B%5Cpi%20%2A%20d%5E2%7D%7B4%7D%20%3D%20%5Cfrac%7B%5Cpi%20%2A%200.01%5E2%7D%7B4%7D%20%3D%207.85e-5%20m%5E2)
Then:
![k = 2.1e11 * \frac{7.85e-5}{0.06} = 275e6 Pa = 275 MPa](https://tex.z-dn.net/?f=k%20%20%3D%202.1e11%20%2A%20%5Cfrac%7B7.85e-5%7D%7B0.06%7D%20%3D%20275e6%20Pa%20%3D%20275%20MPa)
The answer is B because an architect designs buildings
Answer:
BOD5 = 200 mg/L
Explanation:
given data
diluted = 1% = 0.01
time = 5 day
oxygen consumption = 2.00 mg · L−1
solution
we get here BOD5 that is BOD after 5 day
and here total volume is 100% = 1
so dilution factor is
= 100
so BOD5 is
BOD5 = oxygen consumption × dilution factor
BOD5 = 2 × 100
BOD5 = 200 mg/L
