Explanation:
only a fraction of radiation strikes plants or algae and only a portion of that fraction is of wavelengths suitable for photosynthesis and much energy is lost as a result of reflection or heating of plant tissue
Only a small portion of the solar energy that strikes Earth's atmosphere is stored by primary producers primarily due to the limitations and inefficiencies in the process of photosynthesis.
Photosynthesis is the biological process by which primary producers (such as plants, algae, and some bacteria) convert solar energy into chemical energy in the form of glucose (a type of sugar). However, photosynthesis is not a perfectly efficient process, and several factors contribute to the small fraction of solar energy being stored:
Reflection and Absorption: Not all incoming solar energy is absorbed by the plants. Some of it is reflected back into space or absorbed by other substances in the atmosphere, water bodies, or the Earth's surface before reaching the photosynthetic organisms.
Wavelengths: Solar energy reaches Earth in the form of electromagnetic radiation, which includes different wavelengths. Chlorophyll, the primary pigment responsible for capturing light during photosynthesis, is most efficient at capturing certain wavelengths, particularly in the blue and red regions of the electromagnetic spectrum. The rest of the spectrum is less effectively utilized by the photosynthetic organisms.
Light Availability: Photosynthesis requires sunlight, so the amount of energy captured is also influenced by factors like the length of day and cloud cover. Weather conditions can limit the availability of sunlight, impacting the overall energy capture.
Respiration: Plants and other primary producers also use some of the energy they capture for their metabolic processes, including respiration, where they consume glucose to obtain energy for growth, maintenance, and reproduction. This reduces the net amount of energy stored as biomass.
Losses in Growth and Reproduction: Not all stored energy is converted into plant biomass. Some energy is used in growth and reproduction, while some is lost as heat during metabolic processes.
Hence, these factors contribute to the limited efficiency of photosynthesis and explain why only a small portion of the solar energy that strikes Earth's atmosphere is stored by primary producers as chemical energy in their tissues.

The velocity of the rocket is not the same as the speed of the rocket. What is the difference between the velocity of an object and the speed of an object
The difference between the velocity of an object and the speed of an object is that the velocity represents both the magnitude and direction, and speed represents only the magnitude.
What is velocity?
Velocity is the time rate of change of displacement.
Speed is the ratio of distance and the time taken to travel that distance.
Thus, the difference between the velocity of an object and the speed of an object is that the velocity represents both the magnitude and direction, and speed represents only the magnitude.

This Is Chemistry Question, My Laptop Got Lag When I was Posting It :( Explain The Rutherford Atomic Model
Answer Should Be given With Headings!
Explanation:
that’s hard
Answer:
Rutherford conducted an experiment (α-particles scattering) in order to find the arrangement of electrons and protons in an atom. This experiment led to the discovery of nucleus in an atom.
Explanation:
Rutherford bombarded a thin gold foil (about 0.00004 cm thick) with alpha particles in an evacuated chamber. These particles got scattered and were allowed to to strike on a circular zinc sulphide coated screen. He observed a flash of light on the screen where the alpha particles struck. From this experiment, he made the following conclusions.
Observation 1: Most alpha particles (α-particles) pass straight through the gold foil without any deflection from their original paths.
Conclusion: There is a lot of empty space in the atom.
Observation 2: A few alpha particles were deflected, at small angles and a few at large angles.
Conclusion: There is a small positively charged object at the centre of the atom. He said this because as alpha rays are positively charged it can pass through only negatively charged particles and get deflected by the same charge. He concluded that the small positively charged object present within the atom is called the nucleus.
Observation 3: Very few alpha particles completely rebounded on hitting the gold foil.
Conclusion: The nucleus is dense and hard. It is located at the centre of the atom.

Answer:
Increased ; Decreased
Explanation:
Force = Mass x Acceleration
If I increase my mass (by putting in books in the box) shouln't my acceleration go down since they are inversely related to each other (when one goes up, the other goes down and vice versa). My force stayed the same at 10 N, thus only mass and acceleration fluctuated relative to each other.

6. What is a maNged float? What are the disadvantages of freely floating exchange rates that led countries to the maNged float system?
Answer:
Terms in this set (7)
1. Compare and contrast the fixed, freely floating, and managed float exchangerate systems. What are some advantages and disadvantages of a freely floating exchange rate system versus a fixed exchange rate system?
Under a fixed exchange rate system, the governments attempted to maintain exchange rates within 1% of the initi¬ally set value (slightly widening the bands in 1971). Under a freely floating system, government intervention would be non existent. Under a managed float system, governments will allow exchange rates move according to market forces; however, they will intervene when they believe it is necessary.
A freely floating system may help correct balance-of-trade deficits since the currency will adjust according to market forces. Also, countries are more insulated from problems of foreign countries under a freely floating exchange rate system. However, a disadvantage of freely floating exchange rates is that firms have to manage their exposure to exchange rate risk. Also, floating rates still can often have a significant adverse impact on a country's unemployment or inflation.

The U.S. economy grow via trade deficit, if we import more goods and services.
What is import and export?When any good or service is brought in from one country to another is called Import while exports are when goods and services produced in the home country for sale to other countries.
If a country imports more than it exports, it runs a trade deficit. If it imports less than it exports, that creates a trade surplus. When a country has a trade deficit, it must borrow from other countries to pay for the extra imports.
Thus, the U.S. economy grow via trade deficit, if we import more goods and services.
