Consider the two triangles shown below.
attashe74 [19]

Triangles may be regarded as similar or congruent on the following basis;

1) Side angle side (SAS)

2) Side side side (SSS)

3) Angle Angle side (AAS)

<h3>What is a triangle?</h3>

A triangle is a three sided figure. The figures are not shown here. However, two triangle may be regarded as similar or congruent by the following conditions;

1) Side angle side (SAS)

2) Side side side (SSS)

3) Angle Angle side (AAS)

Since the triagles are not shown here, the similarity of the triangles can not be established.

Earth's oceans have an average depth of 3800 m, a total surface area of 3.63 x 108 km2, and an average concentration of dissolve
kakasveta [241]

Answer:

a) Mass of gold in ocean = 8.1*10¹² g

b) Volume of gold = 4.2*10¹¹ cm³

c) Value of gold = $ 4.1*10¹³

Explanation:

a) Depth of ocean = 3800 m

Surface area of ocean = 3.63*10⁸ km²

Now, 10⁶ m² = 1 km²

Therefore, the area in units of m² = 3.63*10¹⁴ m²

Volume\ of\ ocean = Depth*Area = 3800m*3.63*10^{14} m2=1.4*10^{18} m3

Average concentration of gold in ocean = 5.8*10⁻⁹ g/L

Now, 1 g/L = 1000 g/m³

Therefore, concentration of gold in g/m³ = 5.8*10⁻⁶ g/m³

Mass\ of\ gold =1.4*10^{18} m^{3} *5.8*10^{-6} g/m3 = 8.1*10^{12} g

b) Mass of gold present = 8.1*10¹² g

Density of gold = 19.3 g/cm³

Volume\ of\ gold = \frac{Mass}{density} =\frac{8.1*10^{12} }{19.3} =4.2*10^{11} cm^{3}

c) Price of gold = $1595/troy oz

Unit conversion

1 troy oz = 311 g

Therefore, 8.1*10¹² g of gold is equivalent to:

\frac{8.1*10^{12} g* 1\  troy\ oz}{311g} =2.6*10^{10} \ troy\ oz

The value of gold in the ocean is:

\frac{2.6*10^{10} troy\ oz*1595\ dollars}{1\ troy\  oz} =4.1*10^{13} \ dollars

Solid a is a very hard electrical insulator in solid as well as in molten state and melts at extremely high temperature. What ty
devlian [24]

This is covalent network type of solid.

For example, silicon dioxide (SiO₂) is covalent network solid with covalent bonding.

Covalent network solid is a chemical compound (or element) in which the atoms are bonded by covalent bonds in a continuous network extending throughout the material.

Silicon(IV) oxide has continuous three-dimensional network of SiO₂ units and diamond has sp3 hybridization.

This solids do not have free electrons so they are good insulators.

They have strong covalent bonds, so they melt at extremely high temperature.

Other examples are quartz, diamond, and silicon carbide.

How do you think Oxygen can be in the crust when it is a gas at room temperature in the atmosphere?
otez555 [7]

Answer: Through diffusion

Explanation:

Oxygen can be defined as the most abundant element on earth. It is a gas at room temperature. It becomes the part of the earth crust by the process of diffusion.

Diffusion is a process of movement of molecules from a region of high concentration to the low concentration. The oxygen remains in high concentration in the atmosphere diffuses into earth crust at low concentration.
