True strain and engineering strain? True stress is defined as the load divided by the cross-sectional area of the specimen at that instant and is a true indication of the internal pressures. ... Engineering stress is defined as the load divided by the initial cross-sectional area of the specimenAnswer:
Explanation:
Answer:
The diameter increases
Explanation:
The expansion in the metal is uniform in every dimension
Answer:
Compute the number of gold atoms per cubic centimeter = 9.052 x 10^21 atoms/cm3
Explanation:
The step by step and appropriate substitution is as shown in the attachment.
From number of moles = Concentration x volume
number of moles = number of particles/ Avogadro's number
Volume = mass/density, the appropriate derivation to get the number of moles of atoms
Answer: B
Explanation:
One good way to improve your gas mileage is to accelerate smoothly and directly to a safe speed.
Hope this helps!
Answer:
Part A: (d/D=0.1)
DeltaV percent=42.6%
Part B:(d/D=0.01)
DeltaV percent=21.7%
Explanation:
We are going to use the following volume flow rate equation:

Above equation can be written as:


First Consider no wire i.e d/D=0
Above expression will become:


Part A: (d/D=0.1)




DeltaV percent=42.6%
Part B:(d/D=0.01)




DeltaV percent=21.7%
