How many atoms are contained in 1cm of<br> interstellar space?

Lubov Fominskaja [6]

Answer:

0.1 atoms

Step-by-step explanation:

Typically, there is 0.1 atoms in each cubic centimeter of interstellar wind, and 10 ions in each cubic centimeter of solar wind (versus surface air which contains 3 x 10^19 molecules per cc). This means there is a great deal of dead space between the very tiny particles and collisions are rare.

Six pyramids are shown inside of a cube. The height of the cube is h units. Six identical square pyramids can fill the same volu

Amiraneli [1.4K]

The height of squared pyramid is $\frac{1}{3}h$ unit.

<h3>What is the volume of a cube?</h3>

A cube is a solid three-dimensional object with six square faces or sides, three of which meet at each vertex. One of the five Platonic solids, the cube is the only regular hexahedron. It contains 8 vertices, 6 faces, and 12 edges.

Volume of cube $= (side)^3 \ unit^3$

Given the height of cube is $h$ unit.

Volume of cube is $h^3 \ unit^3$

Let the height of squared pyramid is $x$ unit

Volume of squared pyramid is $\frac{1}{3} h^{2} \times x \ unit^3$

According to the question, we have

Volume of cube = $6 \times$ volume of squared pyramid

$\Rightarrow h^3=6 \times \frac{1}{3}h^2 \times x\\\Rightarrow h^3=2 \ h^2 \times x\\\Rightarrow h=2x\\\Rightarrow x= \frac{1}{2}h$

Therefore, the height of squared pyramid is $\frac{1}{3}h$ unit.

Answer:

sin x° = Opposite / Hypotenuse

x = 3.38

Step-by-step explanation:

sin 70° = x / 3.6

sin 70° × 3.6 = x

x = 0.93969262079 × 3.6

x = 3.38289343483 ~ 3.38

Someone please help me with this

Answer:

<em>50° is the correct answer</em>

Step-by-step explanation:

<u>Right Triangles</u>

The right triangles are identified because they have an internal angle of 90°. The basic trigonometric ratios can be used to find angles and side lengths as needed.

We have a right triangle with the following characteristics:

The hypotenuse is 13 units long

The indicated angle is opposite to the leg of 10 units long.

When we know the length of the opposite side, we use the sine ratio. Let's call θ to the required angle:

$\displaystyle \sin\theta=\frac{\text{opposite side}}{\text{hypotenuse}}$
