Energy

A solar eclipse occurs when the moon passes between the Earth and the sun, blocking all or part of the sun's light. This can result in a partial or total eclipse, where the sun appears completely covered by the moon.

The Sun's energy is essential for life on Earth as it provides light and heat necessary for plant growth through photosynthesis. It also drives weather patterns and ocean currents, influencing climate on a global scale. Additionally, solar energy is a renewable and clean source of power that can be harnessed for electricity generation.

"Gerald Pearson, Calvin Fuller and Daryl Chapin - Efficient Solar Cells "In 1954, three American researchers, Gerald Pearson, Calvin Fuller and Daryl Chapin, designed a silicon solar cell capable of a six percent energy conversion efficiency with direct sunlight. "The three inventors created an array of several strips of silicon (each about the size of a razorblade), placed them in sunlight, captured the free electrons and turned them into electrical current. They created the first solar panels. Bell Laboratories in New York announced the prototype manufacture of a new solar battery. Bell had funded the research. The first public service trial of the Bell Solar Battery began with a telephone carrier system (Americus, Georgia) on October 4 1955." http://inventors.about.com/od/sstartinventions/a/solar_cell.htm
Definition of a Solar Cell - History of Solar Cells

Yes, energy from the sun reaches Earth primarily in the form of radiant energy, also known as solar radiation. This energy is in the form of electromagnetic waves, including visible light, infrared radiation, and ultraviolet radiation, which provide heat and light to our planet.

No, it releases energy to it's surroundings!

No. Kinetic energy is 1/2 times mass times velocity squared - so as you can see, acceleration doesn't even enter the equation. If it accelerates, the speed will change, though, and so will its kinetic energy.

Group II elements (also called alkaline earth metals), have two valence electrons. To fill their outer shell, they therefore become ions with two positive charges, such as magnesium:

Mg -> 2e- + Mg2+

Yes, quality sleep helps to restore energy levels by allowing the body to repair and regulate itself. It is during sleep that the body can replenish its energy stores, repair muscle tissues, and promote overall wellness. Aim for 7-9 hours of quality sleep each night to enhance your energy levels.

the wave which has the highest frequency and energy is the wave of light which was further explained by sir Issac newton.

Compressed natural gas (CNG) is the same as natural gas - the only difference is in the form in which they are stored. CNG is natural gas that has been compressed to reduce its volume for storage and transport, while natural gas is found in its uncompressed form underground.

Solar energy is invisible to the naked eye because it is a form of electromagnetic radiation. However, we can harness solar energy using solar panels, which appear as large flat panels usually mounted on rooftops or in open fields to capture sunlight and convert it into electricity.

The sun's brightness comes from the nuclear fusion happening in its core, which creates immense heat and light. If the sun were a black ball, it would not emit any visible light. Its visible brightness comes from the intense energy released during nuclear fusion.

The time it takes for a heated driveway to warm up can vary depending on the size of the driveway, the temperature outside, and the type of heating system used. On average, it can take anywhere from 15 minutes to a few hours for a heated driveway to reach its desired temperature.

Another name for the solar plexus is the celiac plexus or coeliac plexus.

You will have heat transfer to the pot by radiation from the hot coals and by a combination of conduction and convection as the hot gasses of the fire rise to the pot. You might also have some slight heating by conduction from the metal grill to the pot; the grill gets heated the same way as the pot by radiation and flames but may be slightly warmer than the pot since it is closer to the coals and lies between the flames and parts of the pot resting on it. The total heat transfer from the grill to the pot is probably minimal. We would hope that the contents of the pot get heated by the walls of the pot - by conduction and, if they are fluid, convection.

After the sun in the food chain comes producers, which are organisms that can make their own food using sunlight through photosynthesis. These producers are then consumed by primary consumers (herbivores), which are in turn eaten by secondary consumers (carnivores/omnivores) and so on.

Dear Wiki Questioner,

The Sun is way at the top of the food chain because it is the ultimate source of all of the energy consumed in the entire food chain!

The Sun is continually fusing hydrogen molecules into helium molecules which produces a lot of energy in the Sun and makes it very hot. The Sun gets so hot from this fusion energy that it emits large amounts of electromagnetic radiation (Light!) which travels across space and hits the earth.

Plants (with a few exceptions like the Venus Flytrap and the Cobra Lilly) get all the energy they need from the sun's light, which they can "consume" by a process known as photosynthesis.

Herbivores (Plant Eaters), get all of their energy from the plants that they consume, but since the plants get their energy from the sun, we can say that the Herbivores got their energy indirectly from the sun too.

Carnivores (Meat Eaters), get all of their energy from the other animals they consume. Since the other animals get their energy from the plants, who get their energy from the Sun, we can say that the Carnivores also get their energy indirectly to the sun.

So the process is:

Carnivores ---eat---> Herbivores ---eat---> Plants ---Consume---> Sunlight!

The chain always leads back to the Sun, so we say that the sun is on top of the food chain.

The Big Bang is not an example of free energy. Free energy typically refers to the energy available to do work, whereas the Big Bang was the initial explosion that marked the beginning of the universe and is not related to the concept of free energy.

Sound waves require a medium, such as air, water, or a solid material, to propagate because they rely on the vibration and interaction of particles in that medium to transmit energy. In empty space, there are no particles for the sound waves to interact with, so they cannot travel.

Microwave can be use to transmit pictures.

An energy efficient light bulb uses less CO2 because it requires less electricity to function, which means less fossil fuels need to be burned to generate that electricity. Fossil fuels are a major source of CO2 emissions, so using less electricity results in lower CO2 emissions.

The amount of energy required to produce batteries can vary depending on the type and size of the battery. The production process typically involves a combination of energy-intensive steps, such as mining raw materials, manufacturing components, and assembly. Overall, the energy input for battery production can be significant but can be offset by the energy savings achieved during the use phase of the battery's life cycle.

The solar system is a collection of planets, moons, asteroids, comets, and other objects that orbit around the Sun due to its gravitational pull. It includes eight planets, such as Earth and Mars, as well as their moons, and the dwarf planet Pluto.
