Answer:
3.99 mm
Explanation:
To treat a diffusive process in function of time and distance we need to solve 2nd Ficks Law. This a partial differential equation, with certain condition the solution looks like this:

Where Cs is the concentration in the surface of the solid
Cx is the concentration at certain deep X
Co is the initial concentration of solute in the solid
and erf is the error function
First we need to solve the Cs-Cx/Cs-Co on the left to search the corresponding value later on a table.

We look on a table and we see for erf(z)=0.4284 z=0.40
Then we solve for x

Answer:
a) Rmin ≈ 52 m
b) D = 110.184°
c) Lc ≈ 59 m
d) PT Station = 2827+12.37
PT Station = 2827+78.63
Explanation:
a) Given
v = 70 mph = (70 mph)(1,609 m/1 mile)(1 h/3600 s) = 31.286 m/s
e = 3% = 0.03
f = 0.12
a) We can use the equation
Rmin = v²/(127*(e + f))
⇒ Rmin = (31.286)²/(127*(0.03 + 0.12))
⇒ Rmin = 51.38 m ≈ 52 m
b) We can use the equation
D = 5729.578/R ⇒ D = 5729.578/52
⇒ D = 110.184°
c) We apply the formula
Lc = R*Δ/57.3
If Δ = 65° we have
Lc = 52*65/57.3
⇒ Lc = 58.98 m ≈ 59 m
d) If the PI is station 2827+45.50 we get the tangent length T as follows:
T = R*tan(Δ/2)
⇒ T = 52*tan(65/2) = 33.13 m
then, the station of the PC will be
PC Station = PI - T
⇒ PC Station = (2827+45.50) - (0+33.13) = 2827+12.37
and the station of the PT will be
PT Station = PI + T
⇒ PT Station = (2827+45.50) + (0+33.13) = 2827+78.63
Answer:
Coal or oil-fired power plants generate heat, which is then used to generate steam, which drives turbines that generate electricity.

Batch production is a method of manufacturing where the products are made as specified groups or amounts, within a time frame. A batch can go through a series of steps in a large manufacturing process to make the final desired product.
Tempo decides the speed at which the music is played.
<u>Explanation:</u>
The Tempo of a bit of music decides the speed at which it is played, and is estimated in beats per minute (BPM). The 'beat' is dictated when mark of the piece, so 100 BPM in 4/4 compares to 100 quarter notes in a single moment.
A quick tempo, prestissimo, has somewhere in the range of 200 and 208 beats for each moment, presto has 168 to 200 beats for every moment, allegro has somewhere in the range of 120 and 168 beats for every moment, moderato has 108 to 120 beats for every moment, moderately slow and even has 76 to 108, adagio has 66 to 76, larghetto has 60 to 66, and largo, the slowest rhythm, has 40 to 60.
