Science

Hydrogen and helium are the two main gases that make up the Sun. Hydrogen is the primary component, making up about 75% of its mass, while helium accounts for most of the remaining mass.

Water is considered as a universal solvent.
Water is so versatile that no other solvent can match it.
Water dissolves all polar molecules however non-polar molecules are slightly soluble.

Mercury does not have any moons. It is the only planet in our solar system that does not have any natural satellites orbiting around it.

Virgo is the largest constellation in the zodiac and second largest constellation overall. It occupies an area of 1294 square degrees.

Scientists studied data collected from seismometers left on the Moon's surface by Apollo missions, as well as data from lunar meteorites and satellite missions like the Lunar Reconnaissance Orbiter. By analyzing the Moon's seismic activity and gravitational field, scientists were able to develop a model of the Moon's interior structure, including its core, mantle, and crust.

The sun emits light in all wavelengths by black-body radiation. (Because it is very hot, a lot of this radiation is in the visible range, unlike objects at temperatures we're more familar with, which emit in infrared.)

Because of quantum mechanics, there are only certain orbits an electron can occupy around the nucleus of an atom. Normally, an electron orbits as close to the nucleus as possible, but if energy is added, it can go to a higher orbit. Since only certain orbits are possible, only certain amounts of energy can be absorbed or emitted when moving between orbits.

Quantum mechanics also theorizes that the energy of a photon is determined by its wavelength. So light in certain wavelengths can be, and will be, absorbed more than others before leaving the sun. When the sun's light is separated into its spectrum, dark lines appear where these wavelengths would be.

Different energies are characteristic of different elements, so the lines can indicate what elements are present in the sun.

We call such satellites "geosynchronous". That means the time it takes them to make one revolution around the Earth is the same as the time it takes the Earth to revolve once. Yes, that's one day, 24 hours.

Yes, windiness can vary throughout the year due to seasonal changes in temperature and pressure systems. In many places, spring tends to be windier than summer, and winter can also bring strong winds from weather systems like cold fronts and storms.

Central accelerating force, in the case of an orbit this would be determined by the central mass.

semi-major Radius of the orbit.

eccentricity of the orbit.

The value of the Gravitational constant.

For a central mass reference these four are sufficient. If you consider a 'center of mass' reference however then the mass of the orbital is also required to determine the orbital characteristics.

The Great Fire of London took place on Sept. 2nd to the 5th in 1666

The sun appears to move across the sky due to the Earth's rotation on its axis. This creates day and night as different parts of the Earth are exposed to the sun's light. Additionally, the Earth's orbit around the sun causes the sun's position to change slightly each day, resulting in the changing seasons.

Liquid has the greatest volume compared to gas or solid under normal conditions. This is because liquid particles are more closely packed together than gas particles, but less packed than solid particles, giving liquid a larger volume than both gas and solid.

Chi Cygni is a variable star, meaning its brightness varies cyclically. Chi Cygni's temperature is typically given as 3000 K.

The air at the poles is generally very cold, dry, and clean due to the lack of industrial activity and pollution in these remote regions. However, the air quality can be affected by factors like ozone depletion and occasional transport of pollutants from lower latitudes.

Rain helps to clean the air by washing away particles and pollutants, reducing the amount of interference with light passing through it. This results in clearer air and better visibility, making distant objects easier to see after rain.

A natural spring would be one, an artesian basin another, and underground streams (such as found in cave systems) another again. Possibly a water well would be the commonest example. The above only consider land based systems.

First, you would need a ladder approximately 93 million miles long and able to withstand the massive temperatures the sun creates (the corona is around 1 million degrees, the surface is around 5,000 degrees, and the core is around 15 million degrees Fahrenheit). Even if you had this ladder, the sun has no solid surface against which to prop the ladder, and the Earth's rotation would prevent you from having the legs of the ladder on the ground while still pointing the top of the ladder at the sun. In short, the answer is "No".

A solar eclipse occurs when the moon is between the sun and the earth, and casts a shadow on the earth. The moon is small compared to the earth and the sun, so the shadow does not cover all of the earth.

Yes! - actually they have pretty much caught up.

Several Reasons:

1. With our societies growing health awareness, it is no longer a "healthy" or a desirable practice to starve ones self in order to look attractive to men ( or women ). On the contrary, a woman with a larger backside is normally eating well, and not undernourished.

2. Woman are hitting the gyms a lore more than in the 80s and 70s, and doing their cardio and weight training. That gives volumes and tone to your glutes, and makes your body want to eat more and repair the damage to your muscle.

3. In the entertainment industry a lot of women are no longer starving themselves, and simply taking better care of themselves, and this does not mean eating less, it means eating more quality foods and certainly getting a lot more protein. When you see this standard on TV, you tend to want to look like your favorite celebrity.

4. I have not 100% verified this, but a friend of mine who is a doctor tells me that the kids are eating much more enhanced foods ( hormones, etc ), that contribute to their filling out much more.

5. White people are more into hip-hop these days ;)

6. Also, studies have shown that the most attractive thing to a man, visually, is a very sexy hip-to-waist ratio ( i.e. the hourglass shape ). That indicates a female more capable of being a good mate.

Google "Vida Guerra", and that will completely demonstrate what I am talking about

Neil Armstrong's childhood home in Wapakoneta, Ohio burned down in 1992.

Stratus clouds are also known as low clouds as they form at altitudes below 6,500 feet. They typically appear as a thick, uniform layer covering the sky and are often associated with overcast conditions and light precipitation.

Mercury is a toxic substance and should be handled with extreme caution. If there is a spill, it is best to contact a professional hazardous materials cleanup service for proper disposal. Personal protective equipment, such as gloves and a mask, should be worn when handling any mercury-containing items.

Yes, an organism is any living thing with cells.
