Help me please ????​

Answer:

Sustancia  Masa (g)  Composición (% m/m)

Proteínas      5,5                  4,4

Azúcares      5,0                  4,0

Sodio            0,06               0,048

Potasio         0,15                 0,12

Explanation:

Para calcular la composición porcentual en masa de las sustancias debemos usar la siguiente ecuación:

[tex] \%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100 [/tex]

En donde:

[tex]m_{s}[/tex] es la masa de la sustancia

[tex]m_{sol}[/tex] es la masa del yogurt = 125 g

Para las proteínas:

[tex] \%_{m/m} = \frac{m_{s}}{m_{sol}} \times 100 = \frac{5,5 g}{125 g} \times 100 = 4,4 \% [/tex]

Para los azúcares:

[tex] \%_{m/m} = \frac{5,0 g}{125 g} \times 100 = 4,0 \% [/tex]

Para el sodio:

[tex] \%_{m/m} = \frac{0,06 g}{125 g} \times 100 = 0,048 \% [/tex]

Para el potasio:

[tex] \%_{m/m} = \frac{0,15 g}{125 g} \times 100 = 0,12 \% [/tex]

Answer+Explanation:

Titanium ( in place of iron)

Titanium could be an excellent replacement for iron when it comes to tensile strength versus weight. It would be the first choice as a building material metal and building skeletons/bridges would use titanium instead of iron.

Magnesium alloys (in place of aluminum)

Magnesium alloys potentially met the present demands for lighter and reliable construction. With comparable specific stiffness, higher specific strength and energy absorption magnesium alloys have the potential to replace steel and aluminum alloys.

aluminum (in place of copper)

Most non-copper metal cabling is aluminum, and it is often used in areas where copper is not a likely alternative. However, it is used more now as a replacement than it has ever been. It is cheaper than copper, and its relative density allows for more cable to be made from a ton of aluminum than a ton of copper.

Answer:

E = 3.035× 10-¹⁹J = 1.9eV

f = 4.58 × 10¹⁴Hz

Explanation:

wavelength = 6.55 × 10-⁷m

c = 3 × 10⁸m/s

f = ?

E = ?

a) f = c/wavelength

f = 3 × 10⁸/6.55 × 10-⁷

f = 4.58 × 10¹⁴Hz

b) E = hc/wavelength

E = 6.626×10-³⁴ × 3 × 10⁸/ 6.55 × 10-⁷

E = 3.035 × 10-¹⁹J

1ev = 1.6 × 10-¹⁹J

Therefore E = 3.035/1.6 = 1.9eV

Explanation:

speed of light = wavelength * frequency

frequency =speed of light/wavelength

Let frequency = F

Speed of light = 3.0 *10^8

wavelength = 6.55 * 10^-5 cm = 6.55 * 10^-7m

Therefore F= 3.0 *10^8m/s *6.55 * 10^-7m

F = 196.5Hz

Energy = Planck's constant * frequency

Let energy be E

Planck's constant = 6.63 * 10^-34Joule/ seconds

E = 6.63 * 10^-34 * 196.5Hz

E=1.3027 * 10^-31 J

Explanation:

Cyanide's formula can be found either on google on on a reference table at the "polyatomic ions" table. Hydrogen, H, has a charge of 1+ when bonded, and cyanide has a charge of 1- overall, so they will be in a one to one ratio while bonded. As such, the equation is HCN.

Answer: A

Explanation:

The white Dwarfs are a group of stars that are extremely bright and hot. Hence option A is correct.

Stars are defined as any large gaseous heavenly body that emits light as a result of its own internal energy sources. Stars are celestial bodies that generate their own energy through the fusing of gases. They resemble bright orbs that burn gas and produce energy. Our solar system's star, the Sun, generates energy through the fusion reaction in which helium transforms into hydrogen.

When a white dwarf first forms, it is extremely hot, but because it has no energy source, it will gradually cool as it emits its energy into space. This implies that the color temperature of its radiation, which is initially high, will gradually decrease and turn red. After using up all of their nuclear fuel, stars like the Sun become white dwarfs.

Thus, the white Dwarfs are a group of stars that are extremely bright and hot. Hence option A is correct.

The various levels of the organization of life are as follows:

Cells: a cell is the basic unit of ife

Tissues; A tissue is a group of cells with a common origin. performing similar functions.

Organ: an organ is a group of tissues with varied or similar function that work together to perform a specific function.

System: a system is a group of different organs that work together in the body to perform a specific function.

Since, the leaf is an organ in the plant that performs the function of photosynthesis, the group of dermal cells found on the leaf are in the tissue level of organization, they perform the function of protection for the leaf.

Explanation:

Answer:

Explanation:

Glaciers are melting, sea levels are rising, cloud forests are dying, and wildlife is scrambling to keep pace. It has become clear that humans have caused most of the past century's warming by releasing heat-trapping gases as we power our modern lives. Called greenhouse gases, their levels are higher now than at any time in the last 800,000 years.

We often call the result global warming, but it is causing a set of changes to the Earth's climate, or long-term weather patterns, that varies from place to place. While many people think of global warming and climate change as synonyms, scientists use “climate change” when describing the complex shifts now affecting our planet’s weather and climate systems—in part because some areas actually get cooler in the short term.

Climate change encompasses not only rising average temperatures but also extreme weather events, shifting wildlife populations and habitats, rising seas, and a range of other impacts. All of those changes are emerging as humans continue to add heat-trapping greenhouse gases to the atmosphere, changing the rhythms of climate that all living things have come to rely on.

What will we do—what can we do—to slow this human-caused warming? How will we cope with the changes we've already set into motion? While we struggle to figure it all out, the fate of the Earth as we know it—coasts, forests, farms, and snow-capped mountains—hangs in the balance.
