Answers

It took 380,000 years for electrons to be trapped in orbits around nuclei, forming the first atoms.

These were mainly helium and hydrogen, which are still by far the most abundant elements in the universe. Present observations suggest that the first stars formed from clouds of gas around 150–200 million years after the Big Bang. Heavier atoms such as carbon, oxygen and iron, have since been continuously produced in the hearts of stars and catapulted throughout the universe in spectacular stellar explosions called supernovae.

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

A whale is swimming in the ocean. It communicates with another whale by sending out a sound. Which of the following best
describes how the sound gets to the other whale?
A.
All of the sound absorbed by water changes to heat before getting to the other whale.
В.
The sound is transmitted through water until it reaches the other whale.
C.
All of the sound is diffused in
the water until only a faint sound reaches the other whale.
.D
The sound is reflected in the water before it gets to the other whale.

Answers

Answer:

A.

The sound is transmitted through water until it reaches the other whale.

Explanation:

When one whale makes a sound, the sound is transmitted through water until it reaches the other whale. The sound causes a ripple-like effect in the water, producing waves that travel in the water. The waves are heard in all directions. This is why humans can hear the sounds animals make underwater.

The statement which best describes how the sound gets to the other whale is that all of the sounds absorbed by water change to heat before getting to the other whale. Thus, the correct option for this question is A.

How sound may transmit from one place to another?

The transmission of sounds is generally carried out through a medium in the form of waves. These sound waves involve the pattern of disturbance caused by the movement of energy.

In an aquatic environment, when one whale successfully constructs a sound, the sound is effectively transmitted through the medium that is known as water.

It remains in the form of waves until it reaches the other whale. The sound in a waveform provokes a ripple-like effect in the water and travels in the water. The waves are effectively heard in all directions.

Therefore, the correct option for this question is A.

Hello!

The answer to this question is: D) Generating electricity from a solar panel system.

Thank you for asking this question!

It would be greatly appreciated if you thanked me and marked me as the brainliest!

Have an amazing day.

The energy transformation which produces electricity and is least likely to

negatively impact the environment is generating electricity from a solar

panel system.

Generating electricity from solar panel involves the use of solar energy from

the sun to generate electricity . This type of energy doesn't emit any type of

harmful radiation or release toxic compounds into the atmosphere which

makes it the least likely to negatively impact the environment.

Other options emit any type of harmful radiation or release toxic compounds

into the atmosphere which makes option D the most appropriate.

A rectangular box has the following dimensions on the inside: 5 cm x 5 cm x 10 cm. What volume can the box hold, in milliliters?

- 20 mL
- 259 mL
- 25 mL
- 50 mL

Answers

Answer:

The volume in milliliters is 250mL

Explanation:

The volume of a rectangle is obtained using the equation:

Volume = Length * Width * Height

In the problem, we can take length as 5cm, width as 5cm and height as 10cm. Thus, volume of the rectangular box is:

Volume = 5cm * 5cm * 10cm

Volume = 250cm³

1mL = 1cm³.

That means the volume in milliliters is 250mL

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.
