Answer:
The edge length of a BCC unit cell is 352 pm
Explanation:
When all angles are exactly 90 degrees, all lengths are identical, and each axis is designated by a Cartesian coordinate, the cubic unit cell is the smallest repeating unit (x,y,z). Eight atoms are located at each corner of each cubic cell, and eight other cells share each atom.
Is the fcc a cubic cell?Atoms are found at the corners and centers of every cube face in FCC, which is also a cubic structure. Four atoms make up an FCC unit cell, with each corner atom representing a 1/8 atom and each face center atom representing a 1/2 atom. FCC crystals have an APF of 0.74.
Ferrite is the name of the alpha phase. Steels frequently contain the mineral ferrite, which has a Body Centred Cubic (BCC) structure that is less tightly packed than FCC.
For instance, the cubic crystal structure is made up of three different types of unit cells: plain cubic, face-centered cubic, and body-centered cubic.
The following is the formula for calculating edge length:
a = √8 × r where r = radius and a = edge length
Given: r = 158 pm
changing the values in the formula above.
a = √8 × 175 = 352 pm
Therefore, the edge length will be 352 pm.

newton's second law in 1 dimension: a catcher stops a 0.15-kg ball traveling at 40 m/s in a distance of 20 cm. what is the magnitude of the average force that the ball exerts against his glove?
Explanation:
v=0, u=40m/s, S=20cm =0.2m, mass = 0.15kg.
by the formula,
v²-u²=-2aS
0-1600=-20×0.2×a
-1600/(-2×0.2) = a
4000m/s²=a
Force = mass × acceleration.
F=ma = 0.15×4000 = 600N.

The polynomial [tex]3y^2 (y 7)^ 2 - 15[/tex] after it has been fully simplified and written in standard form as [tex]4y^4 + 34[/tex].
A polynomial is an expression in mathematics that consists of variables (also known as indeterminates) and coefficients.
It involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables. x2 4x + 7 is an example of a polynomial with a single indeterminate x.
A polynomial is a mathematical expression made up of indeterminates and coefficients that only involves the operations of addition, subtraction, multiplication, and positive-integer powers of variables.
To fully simplify and write the polynomial [tex]3y^2(y-7)^2 - 15[/tex] in standard form, we first need to expand the squared binomial:
[tex](y-7)^2 = (y-7)(y-7) = y^2 - 14y + 49[/tex]
Now we can substitute this expression back into the original polynomial and simplify:
[tex]3y^2(y-7)^2 - 15 = 3y^2(y^2 - 14y + 49) - 15\\= 3y^2y^2 - 42y^3 + 147y^2 - 15\\= 3y^4 - 42y^3 + 147y^2 - 15[/tex]
So the fully simplified polynomial, written in standard form, is:
[tex]3y^4 - 42y^3 + 147y^2 - 15[/tex]
Therefore, the correct answer is [tex]4y^4 + 34.[/tex]
