The Moon

The Moon is the only natural satellite of the Earth, and the only celestial body where humans have landed. It is approximately 384,403 kilometers (238,857 miles) away from the Earth, and has an approximate diameter of 3,476 kilometers (2,160 miles).

How would functions of a nose cone and fins differ on the moon?

On the moon, the function of a nose cone would primarily be to reduce aerodynamic drag during descent or ascent in a vacuum environment with minimal atmosphere. Fins, on the other hand, would have little to no effect on stability or control since there is no air to provide aerodynamic forces for maneuvering. Therefore, the primary function of fins on the moon would likely be for structural support or stability during landing.

Why is biosphere absent on moon?

The biosphere is absent on the moon primarily due to its lack of a substantial atmosphere and liquid water, both of which are essential for supporting life as we know it. The moon's surface is also exposed to high levels of radiation and extreme temperature variations, making it inhospitable for most forms of life. Additionally, the moon does not have a magnetic field to shield it from solar winds, further inhibiting the development of a biosphere.

What percent of Americans think the moon is made of cheese?

There is no reliable data or scientific study indicating what percentage of Americans believe the moon is made of cheese. The idea that the moon is made of cheese is a common myth or folktale rather than a scientifically supported belief. Surveys on public perceptions of the moon typically focus on more relevant topics such as lunar exploration, astronomy, or space exploration.

What is cresant moon?

A crescent moon is the shape of the moon when it is less than half illuminated, resembling the curved shape of a banana or a smile. It appears in the sky during the waxing (growing) and waning (shrinking) phases of the moon's cycle.

What object would be a deciliter?

A deciliter is a measure of volume equal to 1/10 of a liter. It is commonly used to report blood contents, as for heavy metals (microgram/deciliter rather than milligrams/100 liters) and cholesterol (LDL value in milligrams per deciliter).

What is the average number of moons per planet?

There are 167 known moons around the eight planets of our Solar System. Therefore the average number of moons per planet is 167/8 which gives 20.875 moons.

The question is obviously about our Solar System, not exomoons, nor the whole universe.

Please add your comments to the discussion board: That is what it is for.

What are the magnitude and direction of the gravitational force that acts on a man who weighs 700N at the surface of the earth?

The magnitude of the force is 700 N.

The direction of the force is straight "down", i.e. toward the center of the earth.

Note: There is also a gravitational force acting on the earth.
The magnitude of the force is 700 N. The direction of the force
is toward the man's 'center of mass', roughly in the middle of
his upper abdomen.

How often are there 13 full moons in one year?

There are typically 12.37 full moons in a calendar year, meaning that it is rare to have 13 full moons in one year. However, this can occur in a year that has an extra full moon, known as a "blue moon." This phenomenon happens approximately every 2-3 years due to the misalignment between the lunar cycle (29.5 days) and the Gregorian calendar year (365.25 days).

How many cats are there on the moon?

Pluto is a dwarf planet, not like a sun or galaxy. Pluto has no "planets" to call it's own. It is part of the Milky Way, and part of a belt surrounding the sun and the rest of the planets. The belt is made up of dwarf planets pulled away from their suns by gravity.

What is bigger the moon or Texas?

Oh, what a delightful question! The moon is much, much bigger than Texas. In fact, the moon is about 3.7 million times larger than the state of Texas. Isn't that just amazing to think about? Just imagine all the beautiful landscapes we could paint on a canvas that big!

How do the distances between the inner planets compare to the distance between the outer planets?

The orbits of the four inner planets are much closer, all orbiting the sun within ¼ billion km. The outer planets are more spread out, but are much larger in size. Their distances roughly double each time as you go out from Jupiter.

Average distances of inner planets from sun;

Mercury, 57,909,175km

Venus, 108,208,930km

Earth, 149,597,890km

Mars, 227,936,640km

Average distances of outer planets from sun;

Jupiter, 778,412,010km

Saturn, 1,426,725,400km

Uranus, 2,870,972,200km

Neptune, 4,498,252,900km

What are the dark seas on the moon called?

Oh, dude, those dark seas on the moon are called "maria." Yeah, like Maria, but with an extra "i." They're not actually filled with water or anything cool like that, they're just big areas on the moon's surface that look darker because of their composition. So, if you're planning a lunar beach vacation, you might want to rethink that.

Is Clint walker still alive?

As of my last available information, Clint Walker passed away on May 21, 2018, at the age of 90. He was an American actor best known for his role as Cheyenne Bodie in the television series "Cheyenne." Walker's legacy in the entertainment industry continues to be celebrated by fans and colleagues.

Does a clock work accurately on the moon?

A clock would work accurately on the moon as long as it's designed to account for the different gravitational conditions. The lack of atmosphere and lower gravity on the moon may cause slight variations, but a specially designed clock would be able to accurately keep time.

Is light from the sun a result of a reflection?

No, the light from the sun is a result of nuclear fusion reactions happening in its core, generating energy in the form of light and heat. This light travels through space and reaches Earth, where it warms the planet and enables photosynthesis in plants.

What is the result of gravity between the Moon and the Earth?

The gravitational interaction of the Earth and Moon produces a number of effects. The most obvious of these is the orbital motion of the Moon around the Earth, but there is also a motion of the Earth around the center of mass of the Earth-Moon system, tidal effects on the Earth and Moon and professional effects on the Earth's axis of rotation.

What is the force with which gravity pulls on objects that are close to earth?

The force depends on the mass of the object. That's why tall fat people weigh more

than short skinny people.

Whatever the mass of the object happens to be, the forces of gravity between the

Earth and the object are 9.8 newtons (about 2.205 pounds) per kilogram of mass,

in both directions.

Is universal gravitation is constant on moon as on earth?

Yes, the universal gravitational constant is believed to be the same across the whole of the universe.

If you traveled 42 miles in 3 hours how many feetdid you travel per second?

42 miles = 221760 feet 3 hours = 10800 seconds 42 miles in 3 hours = 221760/10800 = 20.533 feet pe second

How do you calculate the length of time it takes for a rocket ship to circle the earth?

Distance = (Rate) x (Time) or in this case: Time = Distance / Rate So figure out how far the rocket has to travel (distance) and at what speed (rate) and divide the two numbers.
