What if the Earth was made of wood?
– Physics. Answer the following question in detail. If the Earth were made of wood, the mass of wooden Earth would have been 10\% as much as it is now (without change in its diameter).
What would happen if Jupiter was solid?
Still the biggest solid planet in our solar system, but in no way habitable. The sheer mass of solid Jupiter would make it into a Krypton like planet. The gravity alone would kill any human instantly. The weather conditions they would be at best extreme.
What would happen if Jupiter collided with Earth?
If earth hit Jupiter, the explosion would heat up Jupiter and Jupiter would briefly appear almost as a smaller second sun. The earth would then sink to the core of Jupiter, greatly increasing the gravity and density of the planet.
What would happen if Mars collided with Earth?
Scientists believe that gravitational forces and other factors in space could affect the orbits of planets, which means there’s a chance that Mars could collide with Earth. If this happens, the resulting impact would destroy the entire planet.
At what distance below the surface of the earth the acceleration due to gravity decreases by 10\% of its value at the surface given radius of Earth is 6400 km?
At distance 640 km below the surface of the Earth, value of acceleration due to gravity decreases by 10\%.
How do you calculate the gravitational force between the earth and the sun?
The value of the universal gravitational constant is given by, $G = 6.674 \times {10^{ – 11}}{m^3}/kg{s^2}$. So this is the force of gravitation between the sun and the earth.
Can you walk on Pluto?
Unlike its gaseous neighbors, Pluto is made primarily of rock and ice so it is very possible to walk on. But with only 0.063 surface gravity, as opposed to Earth’s 1g, you would need a considerable amount of weight to remain planted to the ground.
Will humans ever make it to Jupiter?
At the innermost layers of Jupiter that are 13,000 miles deep, the pressure is 2 million times stronger than what’s experienced at sea level on Earth, and temperatures are hotter than the sun’s surface. So clearly, no human is going to be able to venture too far down into Jupiter’s depths.
Is Earth going to crash into another planet?
Could a planet ever collide with Earth? Scientists say it’s highly unlikely. While large-scale collisions were prevalent when our solar system was young, it would be extremely rare for one to occur in a stable and established system like our own.
Could another planet collide with Earth?
This was precisely the scenario of the “When Worlds Collide” and also of the 2011 film “Melancholia.” Is it a likely prospect? No. Earth has, after all, gone 4 1/2 billion years since its last planetary collision.
How far away from the surface of the earth does the acceleration due to gravity reduces by 64?
So at the height of 1600 Km the value of the g becomes 64\%of the g. So this is the required answer. Hence option (A) is the correct answer.
What is the planet made out of?
The planet is completely made out of water (that is, any non-water substance makes up a negligible amount of its mass). There may be a non-water atmosphere above, but there’s no stone or metal center; the water goes down to the center. Most or all of the water on the planet’s surface is liquid…
What would happen if the radius of a planet was twice Earth’s?
Twice more. Since the radius is the same the only variable is the mass of the planet. If it is two times higher than on earth, it’s surface gravity will be twice as large. 8 clever moves when you have $1,000 in the bank.
What would happen if the iron core of Earth was replaced?
A planet the same size and 2x the mass would be twice as dense. 11.02x that of water. So this could happen if the iron core of Earth were replaced with Gold which has a density of 19.32 times that of water.
What would a planet with the same size and mass look like?
A planet the same size as Earth but twice the mass would have twice the surface gravity since Now the density of Earth is 5.51x that of water. This is due to Earth’s iron core. Iron is 7.87 times the density of water. A planet the same size and 2x the mass would be twice as dense. 11.02x that of water.
