The answer is: B.warm air rises and takes heat with it eventually it cools and sinks.
Solar radiation is the source of electric energy.
The thermal radiation is electromagnetic radiation generated by the thermal motion of charged particles in matter.
Heat spontaneously flows from a hotter to a colder body.
The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.
Radiative zone is around the inner core and in this area energy is transported by radiation.
Answer: B.warm air rises and takes heat with it eventually it cools and sinks
Explanation: There are three modes of heat transfer:
1. Conduction: This type of heat transfer happens when there is direct contact between the two object.
2. Convection: This type of heat transfer happens when there is a movement of fluid (liquid or gas) in which convection currents are produced due to the movement of hot fluid upwards and cold fluid downwards. This happens as the density of hot fluid decreases and thus it moves upwards.
3. Radiation: This type of heat transfer happens when there is direct transfer of energy through space.
Warm air rises and takes heat with it eventually it cools and sinks is an example of convection and not radiation.

How many molecules are in 3.2 mol of ammonia,NH3
To find the number of molecules in 3.2 mol of ammonia (NH3), we can use Avogadro's number. Multiply 3.2 mol by Avogadro's number (approximately 6.022 x 10^23 molecules/mol) to get approximately 1.9264 x 10^24 molecules.
Explanation:To calculate the number of molecules in 3.2 mol of ammonia (NH3), we can use Avogadro's number. Avogadro's number is approximately 6.022 x 1023 molecules/mol. So, to find the number of molecules in 3.2 mol of ammonia, we multiply 3.2 mol by Avogadro's number:
Number of molecules = 3.2 mol x 6.022 x 1023 molecules/mol = 1.9264 x 1024 molecules
Therefore, there are approximately 1.9264 x 1024 molecules in 3.2 mol of ammonia.

What started the Russo-Japanese War?
Answer:
Late in the night on February 8, 1904, Japan launched a surprise attack against the Russian-held Port Arthur, along the coast of Manchuria, beginning the Russo-Japanese War.
Explanation:
hope this helps
Final answer:
The Russo-Japanese War started due to territorial disputes in Manchuria and Korea, with Japan launching a surprise attack on Port Arthur in 1904. Japan's victory altered international relations and signaled the rise of Asian military prowess against European powers.
Explanation:
The Russo-Japanese War began primarily due to territorial rivalries in Manchuria and Korea. In the winter of 1904, Japan initiated the conflict with a surprise naval attack on the Russian fleet at Port Arthur because of Russia's military presence in Manchuria and its refusal to recognize Japan's interests in Korea. Industrialization in Japan played a crucial role, enabling its military to achieve rapid victories over Russia. This conflict ended with the signing of the Treaty of Portsmouth in 1905, with Japan gaining control over Korea and parts of Manchuria. The war not only demonstrated Japan's industrial military power but also influenced international dynamics by challenging European influence in Asia and stirring political unrest within Russia.

Final answer:
The fastest environmental changes today include climate change, loss of biodiversity, and alterations to the water cycle, all of which are significantly accelerated by human activities, particularly since the mid-20th century.
Explanation:
Notably, the fastest environmental changes currently occurring relate to climate change, loss of biodiversity, and changes in water cycles. These changes are largely driven by human activities, notably since the mid-20th century, a period often referred to as the Great Acceleration, indicating a steep increase in population growth, GDP, and resource consumption leading to a profound ecological impact. Climate change is one of the most dramatic examples of rapid environmental alteration. It is occurring at a pace unprecedented in human history, with global temperatures projected to rise significantly within a single century, a rate at least 100 times faster than naturally occurring changes. This swift change is too rapid for many social systems, natural species, and ecosystems to adapt, leading to increased risks of extinction, spread of diseases, and more frequent catastrophic natural disasters.
Another swift change is seen in the loss of biodiversity, where species are going extinct at a rate much higher than the natural background rate, primarily due to habitat destruction, pollution, overexploitation, and climate change. Additionally, water cycles are being altered, with some regions experiencing more intense droughts and others more severe flooding, challenging existing agricultural practices and water management systems.

What is the frequency of a wave?
A the distance traveled by the wave during one full cycle
B. The distance from the beginning to the end of a cycle
C. The amount of cycles that occur in a given time
D. the amount of time that one full cycle takes
The frequency of a wave is the distance from the beginning to the end of a cycle. Therefore, option B is correct.
What do you mean by the term frequency ?Frequency is measured in hertz and is defined as the quantity of oscillations of a wave per unit of time (Hz).
The equation f = vλ , where is the wavelength in metres and v is the wave speed in m/s, may be used to determine the frequency of a wave if the wavelength and speed of the wave are known.
The quantity of waves that pass a set location in a predetermined period of time is known as frequency. Hence, if a wave passes through in half a second, the frequency is 2 per second. The frequency is 100 times per hour if it takes 1/100 of an hour.
Thus, option B is correct.

Which structures are found in both plant and animal cells?
W and X
W and Z
X and Y
Y and Z
Answer:
W and Z
Explanation:
W is cell membrane and Z is mitochondria. Both plant and animal cells have cell membrane, which is semi-permeable and slows the exchange of certain molecules in and out of the cell. Mitochondria is present in both animal and plant cells. Mitochondria is known as the powerhouse of cell. ATP through oxidative phosphorylation is generated in the mitochondria.
The wax of a burning candle is a fuel that combines with oxygen in the air. As the fuel is consumed, what happens to most of the energy stored in the bonds of the wax? A. It is used to produce work. B. It stays in the wax. C. It is released as potential energy. D. It is released as heat and light.
Answer:D. It is released as heat and light.
Explanation:
Energy cannot be created nor destroyed but can be converted from one form to another. This is the law of the conservation of energy. Energy is stored in the wax. When the wax is burnt, that energy is converted to another form of energy. In this case heat and light. Energy exists in various forms in nature. Energy is always converted from one form to another.
