Effect of impurities and temperature to surface tension

1 answer:

8 0

In general, surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity. The influence of the surrounding environment is due to the adhesive action of liquid molecules that they have at the interface.

yKpoI14uk [10]

Answer:

P( red | large shirt ) ≠ P( large shirt)

P( Blue | large shirt ) = P( blue shirt)

P( shirt is medium and blue ) ≠ P( medium shirt)

P( large shirt | red shirt ) ≠ P( red shirt)

Explanation:

P( red | large shirt ) = 42/77 = 0.5454 : P( large shirt)= 77/165 = 0.467

P( red | large shirt ) ≠ P( large shirt)

P( Blue | large shirt ) = 35/77 = 0.4545 : P( blue shirt)= 75/165 = 0.4545

P( Blue | large shirt ) = P( blue shirt)

P( Shirt is medium and blue ) = 40/77 = 0.2424 : P( medium shirt)= 88/165 = 0.5333

P( shirt is medium and blue ) ≠ P( medium shirt)

P( large shirt | red shirt) = 42/90 = 0.4667 : P( red shirt)= 90/165 = 0.5454

P( large shirt | red shirt ) ≠ P( red shirt)

Two long, straight wires are parallel and 10 cm apart.One carries a current of 2.0 A, the other a current of 5.0A. (a) If the tw

lubasha [3.4K]

Answer:

Explanation:

Given

Distance between two wires $d=10 cm$

Current value $i_1=2 A$

$i_2=5 A$

(a)If current flows in opposite direction

When current Flows in opposite direction the two wires will repel each other

Force due to current carrying wire $F=\frac{\mu _0i_1i_2}{2\pi r}$

$F_{12}=F_{21}=\frac{\mu _0\times 2\times 5}{2\times \pi \times 0.1}$

$F_{12}=\frac{4\pi \times 10^{-7}\times 2\times 5}{2\pi \times 0.1}$

$F_{12}=2\times 10^{-5} N$ (Repulsive Force)

(b)If current is flowing in the same direction

When direction of current is same then force will be attractive in nature

$F_{12}=F_{21}=\frac{\mu _0i_1i_2}{2\pi r}$

$F_{12}=\frac{4\pi \times 10^{-7}\times 2\times 5}{2\pi \times 0.1}$

$F_{12}=2\times 10^{-5} N$ (attractive Force)

Which type of stress is a uniform stress that doesn't lead to earthquakes?

ElenaW [278]

Answer:

C) Lithostatic pressure

Explanation:

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane.

In the Earth the pressure due to the weight of overlying rocks is a uniform stress and is referred to as confiningstress. If stress is not equal from all directions then the stress is a differential stress. Three kinds of differential stress occur. Shear stress, which result in slippage and translation.
