This is for Python
numbers = [7, 3, 6, 9, 0]
print(numbers.sort())
Output: [0, 3, 6, 7, 9]
numbers = [7, 3, 6, 9, 0]
print(numbers.sort(reverse = True))
Output: [9, 7, 6, 3, 0]
Answer:
Back then, television was seen as a rare and insane device. Now, in 2020, many people have access to television because it is not a new thing anymore and many people own it.
Explanation:
Answer:
a) D = 4.88 * 10^(-14) m^2 / s
b) <em>t </em>= 1.1 hr
Solution:
a) Magnesium in Aluminum diffusion:
D = Do * exp(-Qd / RT)
= (1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15)
= 4.88 * 10^(-14) m^2 / s
D = 4.88 * 10^(-14) m^2 / s
b) The composition remains same at say the distance Xo:
(Cx - Co) / (Cs - Co) = Constant
Xo^2 / D_{550} * <em>t </em>= Xo^2 / D_{450} * 15
D_{550} * <em>t </em>= D_{450} * 15
(1.2 * 10^(-4) m^2 / s) * exp ( - 130,000 / 8.31 * 723.15) * <em>t</em>
(4.88 * 10^(-14) m^2 / s) * 15
by, solving for <em>t </em>we get:
<em>t </em>= 1.1 hr
So, the time required is 1.1 hr.
The answer would be d, none kf the above.
