Assignment Summary For this assignment, you will construct a scientific model of the water cycle to show how water is recycled through an ecosystem. Once you have drawn your model on a poster board, you will write one to two paragraphs explaining how water is transferred within and between organisms and the environment. Background Information Water is a very important compound. Organisms need water to carry out life-maintaining processes such as growth and development. Without water, living things will not survive. Water continually flows among the atmosphere, land, water, and living organisms. This process, called the water cycle, allows water to be recycled as it moves through Earth’s spheres. Materials Assignment Instructions Step 1: For this project, you are expected to submit the following: 1. Your model of the water cycle 2. One to two typewritten paragraphs describing the water cycle Step 2: Prepare for the project. a) Read through the guide before you begin so you know the expectations of this project. Pay particular attention to the instructions you need to follow to create a model on your poster board. b) If anything is not clear to you, be sure to ask your teacher. Step 3: Gather materials for the model. a) Start with a blank poster board. Be sure to put your name on it. b) You may either draw the parts of the water cycle or print images to construct a model on your poster board. Gather any drawing tools that you will need, or print any images you want to use. Step 4: Create a model of the water cycle. a) Your model should include bodies of water such as lakes and oceans, organisms, air, and land. b) Draw arrows indicating how water moves within an ecosystem and between organisms and their environment. Be sure to include the Sun and gravity in your model. c) Include short phrases on your poster that summarize what occurs at each stage of the water cycle Step 5: Write a paragraph describing the water cycle. a) Type one to two paragraphs describing the full water cycle. Be sure to use full sentences and proper grammar.

Answers

Answer:

Explanation:

Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. Water is always changing states between liquid, vapor, and ice, with these processes happening in the blink of an eye and over millions of years.

how many atoms are there in 1g of argon the Avogadro constant is 6.02 x 10^23 per mole relative atomic mass (Ar): AR=40

Answers

Answer:

ow many atoms are there in 1g of argon the Avogadro constant is 6.02 x 10^23 per mole relative atomic mass (Ar): AR=40Explanation:

The number of atoms of argon in 1g of argon is 1.5 × 10²² atoms

From the question,

We are to determine the number of atoms present in 1g of argon.

To determine this,

First we will calculate the number of moles of the 1g of argon

From the formula

[tex]Number\ of\ moles = \frac{Mass}{Atomic\ mass}[/tex]

From the given information

Mass of Argon = 1g

Atomic mass of Argon = 40g/mol

∴ Number of moles of Argon = [tex]\frac{1}{40}[/tex]

Number of mole of Argon = 0.025 mole

Now,

For the number of atoms of argon present

Using the formula

Number of atoms = Number of moles × Avogadro's constant

∴ Number of atoms of argon present = 0.025 × 6.022×10²³

Number of atoms of argon present = 1.5055 × 10²² atoms

Number of atoms of argon present ≅ 1.5 × 10²² atoms

Hence, the number of atoms of argon in 1g of argon is 1.5 × 10²² atoms

The statue of Liberty is made out of copper metal. When it was first constructed, the color of the copper metal was bright burnt orange.
Over time, however, it slowly developed a green color as it was exposed to air. What happened to the statue of liberty?

Answers

When the Statue was unveiled in 1886, it was a shiny brown color, like a penny. By 1906, the color had changed to green. The reason the Statue of Liberty changed colors is that the outer surface is covered with hundreds of thin copper sheets. Copper reacts with the air to form a patina or verdigris.

Hope this helps and good luckkk :)

Explanation:

The green color of the Statue of Liberty was due to the outer surface covered with hundreds of thin copper sheets. Copper reacts with the air to form a patina or verdigis

How does the ionosphere help radio transmission?

Answers

Due to the ability of ionized atmospheric gases to refract high frequency (HF, or shortwave) radio waves, the ionosphere can reflect radio waves directed into the sky back toward the Earth. Radio waves directed at an angle into the sky can return to Earth beyond the horizon.

The model depicts the transmission of energy by electromagnetic radiation. The model depicts a single light wave departing from a source.

What describes the light as electromagnetic waves?Light as a wave: Light is a type of electromagnetic wave that can be represented mathematically (described). A shifting magnetic field is produced by a shifting electric field, according to this paradigm. Light is produced when the electric field changes as a result of the changing magnetic field.Light can be thought of as a wave. Light is a type of electromagnetic wave. A fluctuating electric field, according to this hypothesis, generates a fluctuating magnetic field. The interaction of a changing magnetic field with a changing electric field produces light. When charged particles, such as electrons and protons, move, they generate electromagnetic fields, which transport the type of energy known as electromagnetic radiation, or light.

10. The wavelength of the color red is 650 × 10⁻⁹ m

11. The frequency of the color red is approximately 4.6122 × 10¹⁴ Hertz

12. The corresponding energy  is approximately 3.058 × 10⁻¹⁹ J

Explanation:

10. Given that the wavelength, λ, of the color red is 650 nm, and one nanometer, nm = 10⁻⁹ m, we have;

The wavelength of the color red = 650 × 10⁻⁹ m

11. The frequency, v, of the color red is obtained from the relation, v = c/λ

Where;

c = The speed of light = 299,792,458 m/s

∴ v = 299,792,458/(650 × 10⁻⁹) ≈ 4.6122 × 10¹⁴ Hertz

12. Given that energy emitted by light, E = h × v, where E = 6.63 × 10⁻³⁴ J/s, we have;

E = 6.63 × 10⁻³⁴ J·s × 4.6122 × 10¹⁴ Hz ≈ 3.058 × 10⁻¹⁹ J

Therefore,  the corresponding energy, E ≈ 3.058 × 10⁻¹⁹ J.

Maria walked on a beach made mostly of sand. She walked barefoot
on the beach early in the morning, and the sand was cool. When she
walked in the same area in the afternoon, the sand was hot.
Which statement best describes why the temperature of the sand
increased?

Answers

A: The atoms in the sand were moving more quickly

The statement that the atoms in the sand were moving more quickly best describes why the temperature of the sand is increased. The relationship between kinetic energy and temperature is explained here.

What is the relationship between kinetic energy and temperature?

The temperature of a body is directly proportional to the kinetic energy. The energy acquired by those molecules which are in motion is called the kinetic energy.

The radiation of the sun falls on a number of objects on our surroundings. The objects absorb this energy till afternoon due to which they become hot.

When Maria walked in afternoon, the sand was hot as its particles have gained the kinetic energy due to which they move rapidly from one place to another. So that the sand feels more hot in the afternoon.

Thus the atoms in the sand were moving more quickly best describes the increase in temperature of the sand.
