What substances cannot be separated by steam distillation?

Consider layers of three media of different index of refraction. The thickness of layers is the same, say L. Medium A has index

tatiyna

Answer:

Medium A -> medium C -> medium B

Explanation:

Refraction is defined a s the change in the direction of light rays as it moves from one medium to another. The speed of the light in this media depends on the nature and the refractive indices of the media.

Light has the tendency to travel faster through a medium with low refractive index rather than high refractive index.

Comparing this medias based on the above conclusion

Medium A has index of refraction 1.3; medium

B has index of refraction 1.4 and medium

C has index of refraction 1.35

The light will travel faster in medium A since it have the lowest refractive index followed by medium C then medium B.

Ranking of the media in accordance the time it takes for light to travel through these layers are as shown

Medium A -> medium C -> medium B

To win the game, a place kicker must kick a

masya89 [10]

Answer:

0.57 m

Explanation:

First of all, we need to calculate the time it takes for the ball to cover the horizontal distance between the starting position and the crossbar. This can be done by analzying the horizontal motion only. In fact, the horizontal velocity is constant and it is

$v_x = u cos \theta = (15)(cos 51.7^{\circ})=9.30 m/s$

And the distance to cover is

d = 19 m

So the time taken is

$t=\frac{d}{v_x}=\frac{19}{9.30}=2.04 s$

Now we want to find how high the ball is at that time. The initial vertical velocity is

$u_y = u sin \theta = (15)(sin 51.7^{\circ})=11.77 m/s$

So the vertical position of the ball at time t is

$y(t) = u_y t - \frac{1}{2}gt^2$

where g = 9.8 m/s^2 is the acceleration of gravity. Substituting t = 2.04 s, we find

$y=(11.77)(2.04)-\frac{1}{2}(9.8)(2.04)^2=3.62 m$

The crossbar height is 3.05 m, so the difference is

$\Delta h = 3.62 - 3.05 =0.57 m$

So the ball passes 0.57 m above the crossbar.

The inertia with the speed of 2.9 m/s has moved a distance of 3.6 kilometers in the west direction and 2.35 kilometers in the north direction.

<h3>What are trigonometric ratio?</h3>

In mathematics, the trigonometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. They are widely used in all sciences that are related to geometry, such as navigation, solid mechanics, celestial mechanics, geodesy, and many others.

Given:

Speed of the speed 2.9 m/s

The direction in which the inertia change is moving = 43° north west.

Time taken to travel the distance = 30 minutes

According to the question that is moving in a Northwest direction with a velocity of 2.9 m per second.

If you want to find the distance it has moved in either North or west direction you will first have to find the total distance that kayak has moved in 30 minutes.

The distance travel by the kayak in 30 minutes = speed of person × time taken

The distance travel by the person in 30 minutes = 2.9 × 30 × 60

The distance travel by the person in 30 minutes = 5220 metre

The distance travel by the person in 30 minutes = 5.22 km

The distance traveled in the west direction can be find using trigonometric ratio.

5.2 × sin 43 = The distance traveled in the west direction

The distance traveled in the west direction = 3.6 kilometers

The distance traveled in the west = cos 43 × 5.2

The distance traveled in the west = 2.35 km

Therefore, The person with the speed of 2.9 m/s has moved a distance of 3.6 kilometers in the west direction and 2.35 kilometers in the north direction.
