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?
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
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?
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.

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.
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.

Answer:
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.

Explanation:
Both the stomach and the small intestine are involved in the digestion of food.
The churning of food by stomach muscles and peptidase enzymes in the small
intestine both break food molecules into smaller molecules.
Which statement best describes changes to food during digestion?
Answer: I think the answer is The muscle contractions result in physical changes, while the action of the peptidase results in chemical changes.
Explanation: Because the muscles would make the food smaller and the enzymes have a chemical change to it because it changes the molecules in the food.
The chemical processes in food digestion results in the formation of new
substances.
The statement that best describes the changes in food during digestion is;
The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.
Reasons:
The given processes in the digestion of food are;
Stomach: Food churning is the process by which the small intestine vigorously turns ingested food.
Small intestine: The action of the peptidase enzyme is to increase the rate of the digestion of food.
Therefore;
The churning of the food is a physical process, which results in physical changes while the peptidase results in chemical changes of the food.

what is the reaction type of 3ZnS+ 2AlP = 1Zn3P2 + 1Al2S3 ?
Answer: double displacement
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The balanced chemical equation is:
[tex]3ZnS+2AlP\rightarrow Zn_3P_2+Al_2S_3[/tex]
Thus as ions get exchanged , it is double displacement reaction.

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.To Learn more About electromagnetic radiation, Refer:
