Energy

Early scientists, like Isaac Newton, speculated that the source of energy from the sun could be due to its particles carrying heat or being composed of combustible material. It was not until the early 20th century that the true source of the sun's energy was discovered to be nuclear fusion in its core.

In the observable UNiverse there are somewhere in the order of 1011 galaxies, a typical galaxy might have 1011 stars, and it seems likely that most stars have planets and would therefore qualify as "solar systems". That makes for a total of roughly 1022 stars or solar systems (that is a one, followed by 22 zeroes), just in the observable Universe. Note that the total Universe is probably much larger, but it isn't currently know how much larger. All of the above are rough estimates, of course.

Voyager spacecraft were too far away from the Sun to rely on solar energy. Instead, they used radioisotope thermoelectric generators (RTGs) to convert the heat generated by the decay of radioactive isotopes into electricity. This allowed Voyager to continue operating in the dark reaches of space where solar power would have been ineffective.

Wind turbines convert the kinetic energy of the wind into mechanical energy, which is then transformed into electrical energy. They do not convert energy directly back into potential, kinetic, or thermal energy.

Yes because my name is heaven! Its kinda fun to have the name heaven, But everyone is saying" I love that name" so its quit annoying! But again your name can be heaven X)

Sunspots are most numerous during solar maximum, which occurs approximately every 11 years. During solar minimum, the sun is less active and sunspot activity decreases.

Our star or AKA the sun it is the largest object in our solar system it alone acounts for about 98.88 percent of all objects mass in our solar system

Solar panels work best when they are both large and fairly close to the sun. Launching a space probe costs thousands of dollars per poundso designers do what the can to minimize weight. For probes that are destined for distant planets and beyond, very far away from the sun, the size of the solar panels needed to provide power to the scientific instruments becomes too great, and the designers instead opt for more compact, economical power supply systems.

They fly at low altitudes because if you fly too high, the balloon may pop.

A2: Above seems unlikely, as the balloon is open at its lower end. Mainly I think because they are generally used for passenger viewing flights and the general public would not have the clothing for high altitudes as well as not wanting to be very high since the purpose of the flight is to view the terrain below. The balloon works by making the air inside hotter and less dense than the surrounding air, so as it rises it needs to use more fuel to achieve this as the surrounding air gets less dense. There must be an effective max height for hot air balloons but I don't know what the record is.

Any area you like. The more area, the more power can be collected. The smallest are but a few square centimeters, or even less, and are used to power calculators.

To my knowledge, the first known intelligent and deliberate use of solar energy by humans dates back approximately 60,000 years. This is the estimated age of a house built by paleolithic humans in what is now Eastern Europe, using what is now called passive solar architecture.

This small structure, cleverly made of interlocking mammoth tusks, featured a single large opening facing due south; the opening is thought to have been designed to use sunlight to warm the abode. The structure was reconstructed and exhibited at the Museum of Natural History in New York City.

Some folks date the first use of solar energy to the use of "burning mirrors" - concentrating solar reflectors - by the Greeks and Romans ca. 100 A.D., as weapons of war to ignite fires and burn sails of enemy war ships.

Photovoltaic (PV) energy - the conversion of sunlight to electricity - dates to 1839 when the property was discovered accidentally by the French experimental physicist Edmund Becquerel, while he was experimenting with an electrolytic cell. The phenomenon was first explained in 1904 by Albert Einstein in his first published scientific paper. He explained the photovoltaic effect by inventing Quantum Theory, and it was for this that he won the Nobel Prize in 1921! Usable PV cells were first made in the early 1950's.

Your question is a bit strange.

Solar energy can be stored in many ways - an underappreciated way of storing solar power is in the form of vegetables. Another is in batteries. Algae is another possibility. A very long term way of storing solar power is by converting it into organic materials (trees, sheeps, and whatevs), crushing them under immense pressure and heat, leave them for a few hundred thousand years, after which you dig them up and use them as a fuel source. So in other words, fossil fuel is actually a roundabout way of using solar power.

The mitochondria is the organelle that transforms chemical energy (in the form of glucose) into ATP, which is the cell's main energy currency.

In the Northern Hemisphere, the places that receive maximum solar energy in December are typically located near the equator or in the Southern Hemisphere where it is summer. Locations like the Tropic of Capricorn or tropical regions in countries like Australia or Brazil receive peak solar energy during this time due to the tilt of the Earth's axis and the position of the sun.

Over half is either reflected, deflected or absorbed as it enters our atmosphere. Of the remaining 47% that hits our planet, most is reflected as visible light and passes through the atmosphere and out into space. Some energy is absorbed by the planet and released as infrared radiation. A small portion of this is absorbed by water vapor and CO2 and is released at night to keep the planet warm and alive.

hello Michael pie

they can be big or small

The average maintenance cost for a solar panel is typically low, as they require minimal upkeep. Basic maintenance includes cleaning the panels periodically to remove dirt and debris, as well as checking the connections and performance regularly. Costs may vary depending on the size of the system and any additional services required.

Yes, light can curve due to gravitational pull, a phenomenon predicted by Einstein's theory of general relativity. This effect, known as gravitational lensing, occurs when light from a distant object is bent as it passes near a massive object, such as a galaxy or black hole, resulting in distorted or magnified images.

It is possible for a solar storm to occur in 2012 as they are a natural part of the Sun's cycle. However, predicting the exact timing and intensity of solar storms is difficult. It is always important for individuals and organizations to stay informed about space weather forecasts and take necessary precautions.

Yes, the sun drives weather on Earth by providing the energy that powers the water cycle and atmospheric circulation. Solar radiation heats the Earth's surface, causing temperature differences that drive wind patterns, ocean currents, and the formation of clouds and precipitation.

The potential and kinetic energy of a system with moving parts is called mechanical energy. Potential energy is the energy stored in an object due to its position or state, while kinetic energy is the energy possessed by an object in motion. The sum of an object's potential and kinetic energy is its mechanical energy.

Quite simply, you get less solar energy than when it is not cloudy. For example, a solar stove can still heat water, but it will no longer boil.
