Answer:
λ^3 = 4.37
Explanation:
first let us to calculate the average density of the alloy
for simplicity of calculation assume a 100g alloy
80g --> Ag
20g --> Pd
ρ_avg= 100/(20/ρ_Pd+80/ρ_avg)
= 100*10^-3/(20/11.9*10^6+80/10.44*10^6)
= 10744.62 kg/m^3
now Ag forms FCC and Pd is the impurity in one unit cell there is 4 atoms of Ag since Pd is the impurity we can not how many atom of Pd in one unit cell let us calculate
total no of unit cell in 100g of allow = 80 g/4*107.87*1.66*10^-27
= 1.12*10^23 unit cells
mass of Pd in 1 unit cell = 20/1.12*10^23
Now,
ρ_avg= mass of unit cell/volume of unit cell
ρ_avg= (4*107.87*1.66*10^-27+20/1.12*10^23)/λ^3
λ^3 = 4.37
Answer:
The solution code is written in Python 3.
- carYear = 1995
- if(carYear < 1967):
- print("Probably has few safety features.\n")
- if(carYear > 1970):
- print("Probably has head rests. \n")
- if(carYear > 1991):
- print("Probably has electronic stability control.\n")
- if(carYear > 2002):
- print("Probably has airbags. \n")
Explanation:
Firstly, create a variable, <em>carYear</em> to hold the value of year of the car make. (Line 1)
Next, create multiple if statements as required by the question (Line 3-13). The operator "<" denotes "smaller" and therefore <em>carYear < 1967</em> means any year before 1967. On another hand, the operator ">" denotes "bigger" and therefore <em>carYear > 1970 </em>means any year after 1970.
The print statement in each of the if statements is done using the Python built-in function <em>print()</em>. The "\n" is an escape sequence that create a new line at the end of each printed phrase.
Step 1- put shoe on
Step 2- grab the laces and cross them
Step 3- once you crossed them pick them back up and put one underneath one.
Step 4- tighten it then make two bunnies
Step 5- put on bunny over the other then loop it around
Step 6 pull the loops and bam you now know how to tie your shoes
