Answer:

m2 will be 78 because sum of angles in a strt line is 180 hence if m1 is 102 then m2 will be (180-102) i.e.78

Determine and state the maximum error of the function G(x,y,z)=20 ln⁡(xyz^2 ) using differentials when (x,y,z)=(2,3,4) and given
Leona [35]

Answer:

The maximum error in the function G, ΔG = ±4

Step-by-step explanation:

G(x,y,z) = 20 In (xyz²)

Total or maximum error for a multi-variable function is given by

ΔG = (∂G/∂x) (Δx) + (∂G/∂y) (Δy) + (∂G/∂z) (Δz)

(∂G/∂x) = 20yz²/xyz² = 20/x

(∂G/∂y) = 20xz²/xyz² = 20/y

(∂G/∂z) = 40xyz/xyz² = 40/z

Δx = ±0.10

Δy = ±0.15

Δz = ±0.20

ΔG = (∂G/∂x) (Δx) + (∂G/∂y) (Δy) + (∂G/∂z) (Δz)

ΔG = (20/x) (0.10) + (20/y) (0.15) + (40/z) (0.2)

At the point (x,y,z) = (2,3,4)

ΔG = (20/2) (0.10) + (20/3) (0.15) + (40/4) (0.2) = 10(0.10) + 20(0.05) + 10(0.2) = 1 + 1 + 2 = 4

ΔG = ±4

Es la capacidad de un material para permitir que permitir que un liquido pase a trabes de el sin que se altere
pogonyaev

Answer:

Permeabilidad

Step-by-step explanation:

La permeabilidad es la medida de la capacidad o facilidad con la que un medio o material poroso permite el paso o la penetración de un fluido (líquido o gas) a través de él.

Un material altamente permeable como la grava permite que el fluido fluya a través de él fácilmente con poca restricción, de modo que prácticamente todo el fluido tiene el potencial de fluir a través de una columna de grava.

Un material poco permeable como la arcilla impide o restringe el flujo de fluido a través de él.

La permeabilidad se mide en un laboratorio utilizando muestras centrales de un material.

La unidad de permeabilidad es m²
