A lot of plants and animal could possibly die because of the added weight, building may collapse and people may live through it and eventually adapt to the change as would any other surviving plants and animals.
Earth's Gravity would pull it straight down to earths surface.
Your weight would be double what it is now.
From the Law of Gravity, F=(GmM)/rr where M is the mass of Earth and m the human mass, G=6.67*10^(-11) r is Earth's radius The force F is F=mg also mg=weight where g is the acceleration due to gravity and m the human mass Putting them together, we get that the acceleration due to gravity g, is g=GM/rr From this, we get that if the mass of the Earth was doubled, then the acceleration due to gravity would be doubled. So, F=m2g this means that the human weight would be doubled as well I think the derivation is correct.
If the radius of the Earth were doubled, you would experience approximately one-fourth (1/4) of the original gravity. This is because gravity is inversely proportional to the square of the distance between two objects, so doubling the radius would reduce the gravitational force by a factor of 4.
If you were on the moon your weight would lower, as there is no gravity.
if you double the earths density say , standing at the surface you would experience twice the acceleration, weight would be doubled
If acceleration due to gravity doubled, your weight on Earth would also double. This means that the force of gravity pulling you downward would be twice as strong as it is currently, causing you to feel heavier.
Earth's Gravity would pull it straight down to earths surface.
Your weight would be double what it is now.
because all are measured at the same radius from the earths cog, if you doubled this distance, the acceleration would be only one quarter that of the surface

The Gravity would Double.
Nothing would happen to mass, but as weight is technically a force due to gravity, based on mass, the weight would be doubled, but again mass would remain the same.
no
Both mercury and mars have a gravity which is around 38% of earths. Mercury's gravity is 37.8% of earths, Mars' gravity is 37.7% of earths.
If both dimensions are doubled then the area is quadrupled. This is true of any geometric shape.
The surface gravity on Mars is the weakest, it is 37.6% of Earths.
