Which statement describes how heat is transferred by radiation?
Air molecules touch the warm ground, heating them up.
Sunlight travels through space without the aid of fluids or solids.
Air at the equator rises and sinks at the poles.
Warm air rises and takes heat with it; eventually it cools and sinks.
Answers
Answer:
convection current waves
Explanation:
The study of chemicals is called chemistry.
The correct answer is D.
The heat convention is stated as the transfer of heat from one place to another due to the movement of fluid. Although often discussed as a distinct method of heat transfer, convective heat transfer involves the combined processes of conduction and advection.
According to the question, the warm air rises up and travels along with the air.
The hot air also has a high temperature due to which the radiation of the heat transfer from one place to another.
Hence, the correct answer is D that is Warm air rises and takes heat with it; eventually, it cools and sinks.

The forces from below the surface that change the surface of the earth are
Erosion
Earthquakes
Volcanoes
Living things
Weathering
Faulting
Folding
Glaciers
Answers
Correct! The forces from below the surface that change the surface of the Earth include:
1. Erosion: The process of wearing away the Earth's surface by wind, water, ice, or other geological agents.2. Earthquakes: Sudden movements of the Earth's crust caused by the release of energy in the Earth's interior, resulting in shaking and sometimes surface displacement.3. Volcanoes: Openings in the Earth's crust through which molten rock, gases, and ash erupt onto the surface. Volcanic activity can lead to the formation of new landforms and alteration of existing ones.4. Weathering: The breakdown and alteration of rocks and minerals at or near the Earth's surface due to various physical, chemical, and biological processes.5. Faulting: The movement and displacement of rock layers along a fault line, typically caused by tectonic forces. This can result in the formation of new landforms or changes in the existing ones.6. Folding: The bending or warping of rock layers due to tectonic forces, resulting in the formation of folds and mountain ranges.7. Glaciers: Large masses of ice that slowly move over the Earth's surface, eroding the land and shaping the landscape through processes like plucking and abrasion.8. Living things: While not a direct force from below the surface, living organisms can play a role in shaping the Earth's surface through activities such as burrowing, root growth, and vegetation cover.These forces, both natural and influenced by living organisms, contribute to the continuous changes in the Earth's surface over time.

Which of the following is true about gravity? Select all that apply.
Answers
Answer:
A and B are the correct answers.
Answer:
A and B are correct
Explanation:
A and B are the most logical answers from the 4 given. This is because just like the moon and Earth, Earth keeps the moon in its orbit with gravity.
A gravitational force can happen with any two objects in the universe. An example of this is a passing asteroid being pulled into Jupiter's atmosphere, because of the gravitational pull. Even two asteroids can have a gravitational pull/force on each other. If there is a big asteroid with smaller asteroids surrounding it, the smaller asteroids will "follow" the larger asteroid.
C is false, because the bigger the mass the bigger the pull (gravitational)
D is also false because if the gravitational force could only exist if there was contact, logically then the moon wouldn't still be orbiting Earth. In other words "Does the moon touch the Earth?" No, it does not "Is the moon still orbiting around Earth without contact?" Yes it is

Question:
which has more calories : table sugar or aspartame ?
Answers
Table sugar, also known as sucrose, contains 4 calories per gram, whereas aspartame contains only 0.2 calories per gram. This makes table sugar much higher in calories than aspartame.
Answer:
Table sugar has more calories than aspartame. A teaspoon of table sugar (4 grams) contains approximately 16 calories, while a teaspoon of aspartame (0.5 grams) contains only 0.4 calories. This is because table sugar is a carbohydrate and contains four calories per gram, while aspartame is a non-nutritive sweetener and is virtually calorie-free.

A chemist is using 341 milliliters of a solution of acid and water. If 16.1% of the solution is acid, how many milliliters of acid are there? Round your answer to the nearest tenth.
Answers
We need to assume that the acid in question is a liquid (not a solid or a gas),
and we need to assume that the 16.1% is specified as 16.1% (v/v) ,
where "v/v" means volume in volume,
meaning 16.2 milliliters of that acid are contained in 100 milliliters of the solution of acid and water.
With those assumptions, the ratio of acid volume to solution volume is
x/342 = 16.1/100 , where x= number of milliliters of acid in the 342
milliliters of solution.
x/342 = 16./100 ---> x=342x16.1/100 ---> x=55 (Rounded)

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.
