Answer:
The number of kilo- grams of hydrogen that pass per hour through this sheet of palladium is
Explanation:
Given
x1 = 0 mm
x2 = 6 mm = 6 * m
c1 = 2 kg/
c2 = 0.4 kg/
T = 600 °C
Area = 0.25
D = 1.7 *
First equation
J = - D
Second equation
J =
To find the J (flux) use the First equation
J = - 1.7 * *
To find M use the Second equation
=
M =
Answer:
a) a = - 0.0524 m/s²
b) t = 6.17 s
Explanation:
Given
τ = 0.18*τ₀ / x
τ₀ = 3.6 m/s
Determine:
a) The acceleration of the air at x= 2m.
Knowing
a = dτ / dt
Multiplying both the numerator and denominator by dx
a = (dτ / dx) (dx / dt)
Substituting τ for dx / dt
a = τ*(dτ / dx)
⇒ a = τ*(-0.18*τ₀ / x²) = (0.18*τ₀ / x)(-0.18*τ₀ / x²)
⇒ a = - 0.18²*τ₀² / x³ = - 0.18²*(3.6)² / x³
⇒ a = - 0.4199 / x³
If x = 2m
⇒ a = - 0.4199 / (2)³
⇒ a = - 0.0524 m/s²
b) The time required for the air to flow from x=1 to x= 3m.
If
τ = dx / dt = 0.18*τ₀ / x
⇒ dt = (x / 0.18*τ₀) dx
⇒ t = (1 / 0.18*τ₀) ∫x dx
⇒ t = (1 / 0.18*τ₀)*(1 / 2)*x²
then
t = (1 / (0.18*3.6))*(1 / 2)*((3)² - (1)²)
⇒ t = 6.17 s
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.

Answer:
a. 2.9218x10^(-29) m^3
b. 7.1230x10^(28) atoms/m^3
c. 2.0812 BM/atom
Explanation:
Atomic radius r = 0.154 nm
saturation flux density Bs = 0.83 tesla
- the formula for the volume of the simple cubic crystal (Vc) = a^3 = (2r)^3
= (2 x 0.154x10^-9)^3
= 2.9218x10^-29 m^3
- The formula for the Bohr magneton per atom with respect to VC, Bs, permeability of the vacuum Uo and magnetic moment per Bohr magneton Ub is;
Bohr magneton per atom nb = (Bs x VC) / (Ub x Uo)
= (0.83 x 2.9218x10^-29) / (9.27x10^-24) x(1.257x10^-6)
= 2.4251x10^-29 / 1.1652x10^-29
= 2.0812 BM/atom
- Number of atoms per Vc, N = nb / Vc
= 2.0812 / 2.9218x10^-29 = 7.1230x10^28 atoms
Answer:
A good one
Explanation:
Rotatianal degrees and stuf for different types of movement would take some proccesing power and if it were linked to brain neurons you would need one not prone to frying
