Newton's law of universal gravitation can be applied to
only to very massive objects
to any two objects with mass
only to objects near Earth's surface
only objects in outer space

Answers

Answer: Only objects near Earths surface
To any two objects with mass because a pencil and a paper can have gravitational force but they won’t be attracted to each other due to earths stronger gravitational pull another example would be meteorites which also have gravitational pull but not enough to be attracted each other unless there’s nothing except them around

Name and describe three measures of central tendency used to summarize data.


Read the assignment carefully and make sure you answer each part of the question or questions.
After you've written your response, go back and read it again to make sure your thoughts are clear.

Answers

Answer:

Explanation:

You can think of it as the tendency of data to cluster around a middle value. In statistics, the three most common measures of central tendency are the mean, median, and mode. Each of these measures calculates the location of the central point using a different method.

There are three main measures of central tendency: the mode(the number that occurs most often) the median ( the middle value in the list of numbers) and the mean (the average number in the list of numbers).

Answer:

The mean, median, and mode are three of the most commonly used measures of central tendency.

Explanation:

Quantitative variables are often summarized using numbers to communicate their central tendency. The numerical average; calculated as the sum of all of the data values divided by the number of values.

What two gases in the atmosphere do animals and plants need to breathe and grow?

Answers

Answer: Explanation:

Plants and animals each produce the gases that the other needs to live. Plants need carbon dioxide—people and other animals exhale carbon dioxide as a waste product. People and other animals need oxygen—plants produce oxygen during an important process called photosynthesis, which turns the sun's energy into nutrients.

Carbon Dioxide for plants and Oxygen for animals

Atlanta’s trees and forests absorb more of the Sun’s radiation, causing higher temperatures than in surrounding regions. The rural areas around Atlanta absorb more heat than the urban areas, causing an overall increase in the city’s temperatures.

How Buoyancy force on an object is related to the weight of liquid it displaces?

Answers

The buoyancy force (B) is equal to the weight (W) of the fluid that a body in that fluid displaces. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy

Archimedes' principle is the statement that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

Describe the 3 layers of the mantle

Answers

Answer:

The 3 main layers are the core, mantle and crust

Explanation:

Answer:

I hope this is the answer for your question

Explanation:

Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km. The mantle is mainly made up of semi-molten rock known as magma. The rock is hard in the upper part of the mantle, but lower down the rock is softer and begins to melt.

The mantle is located directly under the Sima. The mantle consists of very hot and dense rock. This layer of rock flows like asphalt under heavy weight. This flow is because of the greatest temperature differences from the bottom to the top of the mantle. The reason behind the plates of the Earth move is the movement of the mantle. Its temperature varies between 1600 oF at the upper part to 4000 oF near the bottom.

Hardness refers to the strength of the forces holding atoms together in a solid mineral. The Mohs scale will tell how easily a mineral can be scratched. It has a range from 1 to 10. Diamonds are a 10 on the Mohs scale. They are the hardest minerals in the world. The color of a mineral is often easy to identify. Many minerals are found in a range of colors. This is true for diamonds also. They can be yellow, brown, blue, green, orange, purple, black, pink, red, or colorless. Colored diamonds have impurities that cause them to change colors. Colorless diamonds, however, are very pure. Luster refers to how a mineral looks when it reflects light. A minerals luster could be metallic, dull, pearly, or adamantine. Diamonds have adamantine luster–their brilliant sparkle. Streak refers to the color of the powder left by a mineral. Streak is often found after a mineral is scratched on a porcelain tile. The color of the streak left on the tile helps to identify the mineral. The streak of a diamond is white.

Which of the following best describes the relationship between frequency and wavelength of electromagnetic waves?

A. If the frequency remains constant, the wavelength size increases.
B. As the wavelength size decreases, the frequency decreases.
C. As the frequency increases, the wavelength size decreases.
D. If the wavelength remains constant, the frequency increases.

Answers

Answer:

b makes the most sense

Explanation:

Answer:

I think C is the correct answer.

Explanation:

The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

5. The team rallied around their star player, even though now that his leg was broken, the

Answers

Answer:

1: Melodramatic means that you are being more dramatic than the situation calls for.

2: Remorse means guilt;being or feeling sorry for something you have done.  

3: Earnest means showing sincere and intense conviction.

4: Demeanor means outward behavior or baring.  

5: Dismal means depressing or dreary.

Explanation:

1: She started crying and yelling at her parents for not letting her go to a party.

2: He had been blamed and punished for whatever the action he committed.

3: He had made a lot of jokes, so it was hard for people to believe him.

4: Only people who truly knew her could tell when something was wrong

5: The star players leg was broken, so they had no chance of winning their game.

I hope this helps!

1.Melodramatic means to be overdramatic, this helps you understand the sentence more because it makes everything more clear on why she was crying and accusing her parents
2. a sharp pang of remorse basically stating that an intense hurt that had come on suddenly or in shorter terms a deep sadness and pain, this explains that Tom feels horrible because of how Rory is blaming him and punishing him and he is just starting to understand
3. Earnest is to show the results from showing or being sincere and in simpler words being focused on whatever your goal is, this shows that in the beginning Allen made jokes and seemed like a lighthearted kid who didn’t care about what was going on around him then one day he became more serious and started to care for his surroundings
4. Demeanor is how someone behaves and how someone presents themselves the sentence is saying that when something was off about the girl when you really knew her you could tell when something was wrong when she was upset or happy or depressed
5. Dismal means depressing or dreary, the team was sad, depressed, somber about the championship was no longer able to be won
