What would the escape velocity be for a planet with twice the mass of Earth and twice the diameter if the Earth's escape velocity is 11 km per s?
Escape velocity is determined by the formula ( v = \sqrt{\frac{2GM}{R}} ), where ( G ) is the gravitational constant, ( M ) is the mass of the planet, and ( R ) is its radius. For a planet with twice the mass of Earth and twice the diameter, its radius would also be twice that of Earth. Thus, the escape velocity would be ( v = \sqrt{\frac{2G(2M)}{2R}} = \sqrt{\frac{2GM}{R}} = 11 , \text{km/s} ). Therefore, the escape velocity for this planet would remain 11 km/s.
What else can I help you with?
Does the escape velocity on a planet depend upon its density or mass?
No, its depends on the planets gravitational pull
What is the third largest planet diameter?
Uranus is third largest. Diameter = 51115km, about 8 times that of Earths diameter.
What is the escape velocity of planet Jupiter in miles per hour?
The escape velocity of planet Jupiter is: ~133,097.71 miles per hour.
How are the mass of the body and escape speed related?
The greater the mass of the planet, the greater will be the escape velocity.
Is the escape velocity of hydrogen at mars more than it's gravity or in other words can hydrogen in gaseous state exist on the planet mars?
Hydrogen probably cannot exist for a long time on Mars. As you suggest this is because of the planet's fairly low gravity and escape velocity. It's easier for a very light atom or molecule, such as hydrogen, to reach the planet's escape velocity, caused by collisions in the atmosphere.
Does every planet have an escape velocity?
"Escape velocity" is defined as the velocity required in order to guarantee that the object will not fall back under the influence of the planet's gravitational attraction. If it's possible to escape from a planet's gravitational attraction, then an escape velocity can be defined and calculated.
Why would escape velocity be different on a different planet?
The escape velocity is determined by the gravity of the planet which in turn is determined by the mass and size of the planet
To escape from a planet's an object muct reach a speed called the?
To escape from a planet's gravitational pull, an object must reach a speed called the "escape velocity." This velocity depends on the mass and radius of the planet from which the object is trying to escape.
What are the planet's diameters?
Mercury's diameter (at the equator) = 4880km or 0.3825 x Earths diameter Venus' diameter = 12,104km or 0.9488 x Earths Earth's diameter = 12,756km Mars' diameter = 6794km or 0.5323 x Earths Jupiter's diameter = 142,984km or 11.21 x Earths Saturn's diameter = 120,534km or 9.45 x Earths Uranus' diameter = 51,114km or 4.01 x Earths Neptune's diameter = 49,532km or 3.88 x Earths (Pluto's diameter = 2306km or 0.18 x Earths) I included Pluto on the end there, its not classed as a planet any more though, but a dwarf planet.
Does the escape velocity on a planet depend upon its density or mass?
No, its depends on the planets gravitational pull
How can one determine how to find escape velocity in a given scenario?
To find escape velocity in a given scenario, you can use the formula: escape velocity square root of (2 gravitational constant mass of the planet / radius of the planet). This formula takes into account the gravitational pull of the planet and the mass and radius of the planet. By plugging in these values, you can calculate the escape velocity needed to leave the planet's gravitational pull.
What does the term 'escape velocity' mean?
Escape velocity is the minimum velocity needed for an object to break free from the gravitational pull of a celestial body, such as a planet or moon. It allows an object to overcome gravity and travel into space without being pulled back. The specific escape velocity depends on the mass and radius of the celestial body.
What is the third largest planet diameter?
Uranus is third largest. Diameter = 51115km, about 8 times that of Earths diameter.
What is the escape velocity of planet Jupiter in miles per hour?
The escape velocity of planet Jupiter is: ~133,097.71 miles per hour.
How are the mass of the body and escape speed related?
The greater the mass of the planet, the greater will be the escape velocity.
Which planet is most like earth in size and mass?
Venus is closest to the Earths size and mass - often referred to as Earths sister or twin planet. Venus' Mass is around 82% of Earths, while its diameter is a little smaller than Earths at around 95% of Earths diameter.
How fast must an object go to leave a planets gravity?
The speed that ab object must travel at to escape a planet's gravity is called escape velocity. This value varies depending on the mass and diameter of the planet. Here are the escape volcities of the eight planets of our solar system. Mercury: 9,400 mph Venus: 23,000 mph Earth: 25,000 mph Mars: 11,000 mph Jupiter: 133,000 mph Saturn: 77,000 mph Uranus: 48,000 mph Neptune: 53,000 mph Note that escape velocity only takes gravity into account and ignores other forces. An object launched from Earth's surface or from any other planet with a substantial atmosphere at escape velocity would be quickly destroyed and slowed down by air resistance.
