What is the best explanation for how the solar nebula was cleared of debris quizlet?
The solar nebula was cleared of gas through the pressure of the sunlight (called radiation pressure) and through the massive solar wind. The nebula was cleared of some of the leftover debris by the Heavy Bombardment period.
What evidence can you give that the solar system formed about 4.6 billion years ago?
Radioactive dating of rocks from the moon tells us that the moon, and hence the solar system, must be at least 4.48 billion years old. Radioactive dating of rocks from Mars indicate that it must be at least 4.5 billion years old, and radioactive dating of meteorites indicates that they are about 4.6 billion years old.
What evidence can you give that the solar system formed about billion years ago?
What evidence can you give that the Solar System formed about billion years ago? Radioactive dating of meteorites. Dating of the oldest rocks from Earth and the Moon shows lesser ages but they are consistent with the estimate from meteorites.
Why do terrestrial planets not have rings quizlet?
Why don’t terrestrial planets have rings like the Jovian planets? they do not have large enough masses to hold onto orbiting particles and they are too close to the sun, whose gravity would pull those particles away from them. the Oort cloud and Kuiper belt by the gravitational fields of the outer planets.
Is there a 9 planet?
The order of the planets in the solar system, starting nearest the sun and working outward is the following: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune and then the possible Planet Nine. If you insist on including Pluto, it would come after Neptune on the list.
What is my age on Mars?
A year on Mars is longer than a year on Earth—almost twice as long at 687 days. This is roughly 1.88 times the length of a year on Earth, so to calculate your age on Mars we simply have to divide your Earth age by 1.88.
Can we live on Pluto?
It is irrelevant that Pluto’s surface temperature is extremely low, because any internal ocean would be warm enough for life. This could not be life depending on sunlight for its energy, like most life on Earth, and it would have to survive on the probably very meagre chemical energy available within Pluto.
Would you age faster on Mercury?
Originally Answered: On which planet of the solar system will I age slower than on earth? Mercury wins. It’s the planet where you are in the deepest gravity well when you stand on its surface. A lower gravitational potential means a slower passage of time.
Do you age faster on other planets?
No, you wouldn’t age faster, but it would count your age differently. If the other planet had the same day length but different year length, you would probably count every 365 days as a year, instead of every rotation, if you wanted to keep time with earth.
Do you age faster on Jupiter?
Einstein’s general theory of relativity explains time dilation. That means that “standing” on Jupiter, which isn’t possible due to the gaseous surface, will cause you to move through time faster; but you do not age slower.
Is time slower on Neptune?
because the gravity of Neptune is much bigger that the gravitation of Mercury, than the time will pass slower for the person on Neptune that for the person on Mercury. If you live at higher altitude on earth, time is passing slower for you than for people on plain).
How old would I be if I was on Saturn?
A year on Saturn is longer than a year on Earth—29½ years (10,759 Earth days). This is roughly 29.46 times the length of a year on Earth, so to calculate your age on Saturn we have to divide your age in Earth years by 29.46. Note: Saturn is a gas planet so you can’t really be “on Saturn”.
Would you age faster on Venus?
Actually, a human would not age at all on Venus, rather they would quickly die due to its atmosphere. See, a day on Venus is equivalent to 243 days on earth, because it spins (Rotates on its axis completely once) much much more slowly than earth, so it completes that one rotation on its axis in 243 Earth days.
Will you age faster on Mars?
Mass of Mars is lesser than that of Earth which means the time passes faster there relative to Earth. Hence, you would age faster on Mars relative to Earth.
What is the age of Venus?
4.503 billion years
What is my weight on other planets?
Your weight on other planets is a result of your mass, the strength of gravity on the planet and the distance you are from the centre of it. Your mass doesn’t change on other planets, but the gravity and size of those planets affects how much you weight. This is why astronauts are able to jump so high on the Moon.
On which planet would your weight be closest to your weight on Earth?
Venus
What is your weight on Neptune?
The surface gravity on Neptune is about 110% of the surface gravity on Earth, so if you weigh 100 pounds on Earth, you would weigh 110 pounds on Neptune (assuming you could find someplace to, well, stand).
How do you calculate weight on Earth?
Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.
What is the heaviest thing in the world?
In terms of actual weight, the heaviest object ever directly weighed, according to Guinness World Records, is the revolving service structure of the launch pad at the Kennedy Space Center in Florida, clocking in at 4.86 million pounds.
What is my weight for my age?
