Answer:
(a)
(b)
Explanation:
(a)
Volume, V of unit cell
Number of unit cells, N
Where
is weight of material and
is density of material
(b)
Number of atoms in paper clip
This is a product of number of unit cells and number of atoms per cell
Since iron has 2 atoms per cell
Number of atoms of iron=
Answer: vehicles with a front engine and FWD or a rear engine and RWD.
Explanation But the transaxle can also be integrated into the rear axle on cars with a front engine and rear-wheel drive. The transaxle is in the rear where the differential would be rather than beside the engine.
The maintenance is in charge of controlling that all the machines of a company are constantly running in order to avoid damages that cause loss of money when the machines fail.
The maintenance based on vibration monitoring allows to predict failures in some rotating machines such as:
1. worn bearings
2.alignment
3.balance
4. affected gears
5. bent shafts
6. rocks
7.gags
8. eccentricity
9. failures of electrical origin
Answer:
The resistance is 24.9 Ω
Explanation:
The resistivity is equal to:

The area is:
A = 60 * 60 = 3600 um² = 0.36x10⁻⁴cm²

If NA is greater, then, the term 1/NA can be neglected, thus the equation:

Where
V = 0.44 V
E = 11.68*8.85x10¹⁴ f/cm


The length is:
L = 10 - 0.335 = 9.665 um
The resistance is:
