Answer:
45 Mpa
Explanation:
The maximum shear stress, 
is given by
Where T is the torque and d is the diameter.
Substituting 29820.586 N.m for T and 0.15m for d then we obtain
Answer:
The concentration of benzene in this contaminated lake would be 653549ng/L.
Explanation:
The concentration C of a contaminant over a body of water of volume V can be obtained as:
C=Mass contaminant / V
In this case, the volume of the body of water:
The mass of the contaminant (Benzene):
Therefore:
Answer:
Option C
In the membrane that covers axons
Explanation:
Voltage-regulated channels allow for selective passage of different beneficial ions such as potassium and are found on the surface of a wide variety of cells such as nerve, muscle, and secretory cells. They mainly regulate cell membrane excitability, repetitive low frequency firing in some neurons, and recover the nerve fiber membrane.
Answer:
The Estimated uncertainty in a nominal displacement of 2 cm at the design stage is plus or minus 0.0124cm
Explanation:
uncertainty in a nominal displacement
= (u^2 + v^2)^(1/2)
assume from specifications that k = 5v/5cm
= 1v/cm
u^2 = (0.0025*2)^(2) + (0.005*10*2)^2 + (0.0025*2)^2
= 0.01225v
v = 2v * 0.001
= 0.002v
uncertainty in a nominal displacement
= (u^2 + v^2)^(1/2)
= ((0.01225)^2 + (0.002)^2)^(1/2)
= 0.0124 cm
Therefore, The Estimated uncertainty in a nominal displacement of 2 cm at the design stage is plus or minus 0.0124cm
