Answer:
The given statement "A negative normal strain can be considered to increase or decrease volume depending on coordinate system used" is
b) False
Explanation:
Normal strain refers to the strain due to normal stress which is when the applied stress is perpendicular to the surface.
Negative normal strain results in compression or contraction further leading to a decrease in volume while a positive normal strain results in elongation thus giving rise to an increase in volume.
Answer:
The answer is 2217.32m³
Explanation:
Given that:
V₂ = (15 + 5/2) * 3 * 100 = 3000 m³
r₁ = 21.7kN/m3
w (water) = 11.4%.
e₂ (void ratio) = 0.47
V₁ = ?
Now,
rd₁ = r₁/1 + w₁ = 21.7/1 +(11.4/100)
= 19.47 kN/m3
Thus,
rd₂ = r₁/1 + e₂ = 21.7/1+ 0.47 = 14.76 kN/m3
Then,
V₁/V₂ = rd₁/ rd₂
V₁ = 3000 * 14.76/19.97
V₁ = 2217.32m³
Therefore, volume that should be excavated from the borrow pit is 2217.32m³

Explanation: For main group elements, the number of valence electrons is the same in every element in the same group. Group 1 elements have 1 valence electron in the s orbital.
The correct answer and most accurate one will be 44.25
