What will happen to your weight if the Earth expands with its mass remaining the same?
Doubling the mass of the Earth would double your weight, since gravitational force is directly proportional to mass, but doubling the radius (which doubles if the diameter doubles) would decrease your weight by a factor of 1/4, since gravitational force is inversely proportional to the square of the radius.
How would your weight be different if Earth’s radius were larger or smaller than it is but Earth’s mass remained the same?
If you are above the surface of the Earth, then r is greater than the Earth’s radius, so the gravitational force (and your weight) would be less. Your weight would be less because the gravitational field inside the Earth is less than the gravitational field at the surface.
What would happen if the mass of the earth decreased?
If the mass will decrease, then gravitational attraction between earth and sun must decrease, and its angular momentum must decrease, which would result in greater orbit of earth and earth being cooler over the time, but instead the temperature of earth is increasing, why is it so?
Where would you weigh the most inside the earth on the surface of the earth or above the surface of Earth?
Originally Answered: Where on earth would I weigh the heaviest? You will weigh more at the pole because you are closer to the earth’s center of gravity as earth is flattened at the poles.
How much gold is in the earth’s surface?
While it’s not economically feasible to extract much gold, there are about 1 million tons of gold in the top kilometer of the Earth’s surface. The abundance of gold in the mantle and core is unknown, but it greatly exceeds the amount in the crust.
Why is there gold in the Earth’s crust?
As the Earth formed, heavy elements such as iron and gold sank toward the planet’s core. If no other event had occurred, there would be no gold in the Earth’s crust. But, around 4 billion years ago, Earth was bombarded by asteroid impacts. These impacts stirred the deeper layers of the planet and forced some gold into the mantle and crust.
Does gold come from Outer Space?
It is fair to conclude that gold comes from outer space. How Are Different Gold Deposits Formed? Of course, there are different kinds of accessible gold deposits. This precious metal has been found in streams, in the sides of rock outcroppings, and of course, under the earth.
Was there once more gold on Earth than present?
Professor Elliot and Doctor Willbold from Bristol University in England worked on their hypotheses that gold contents at the earth’s surface were once much, much higher than at present. The men received funding from the Natural Environment Council, the Deutsche Forschungsgemeinschaft, and the Science and Technology Facilities Council.
