Answer : The crystal structure of Niobium is, BCC (Z=2)
Explanation :
Nearest neighbor distance, r =
Atomic mass of niobium (Nb) = 92.91 g/mole
Avogadro's number
First we have to calculate the cubing of edge length of unit cell for BCC and FCC crystal lattice.
For BCC lattice :
For FCC lattice :
Now we have to calculate the density of unit cell for BCC and FCC crystal lattice.
Formula used :
.............(1)
where,
= density
Z = number of atom in unit cell (for BCC = 2, for FCC = 4)
M = atomic mass
= Avogadro's number
a = edge length of unit cell
Now put all the values in above formula (1), we get
From this information we conclude that, the given density is approximately equal to the density of BCC unit lattice.
Therefore, the crystal structure of Niobium is, BCC (Z=2)

Answer:
They will pay more taxes if they value inventory using LIFO.
The difference in taxes between the two methods is $8400($ 32,550.00 minus $ 24,150.00)
Explanation:
The oil distributor will pay more taxes using LIFO method in valuing the cost of goods sold because LIFO would pick the prices of goods recently purchased which were lower overall compared to prices of goods earlier purchased.
Hence,inventory sold is charged with lower prices and eventually lower costs of good sold s well higher gross profit which translates into higher taxes.
It would be preferable to value inventory sold using FIFO so as to reduce taxes payable by $8400.
Find attached detailed computation.
Answer:
a) 280MPa
b) -100MPa
c) -0.35
d) 380 MPa
Explanation:
GIVEN DATA:
mean stress
stress amplitude
a)
--------------1
-----------2
solving 1 and 2 equation we get
b)
c)
stress ratio
d)magnitude of stress range
= 280 -(-100) = 380 MPa
