No, it wouldn't. Eath is much larger no matter how many kg of lead there is. Mashmallows are much too small. Earth is very big.
Which is lighter 1kg of rocks or 1kg of marshmallows
they are the same
Yes, that's right. Except instead of calling it "the amount of gravity", it should really be "the force of gravity". In both cases, the force is 9.8 newtons, which is about the same as 2.2 pounds.
Kilograms are weights, cups are volumes. They are not directly exchangeable. 81kilos of marshmallows would be a whole lot more cups than 81 kg of lead.
Because pounds measure weight. A pound of feathers would be a whole lot bigger than a pound of lead.
The element lead is part of the Earth. The lead that we use in everyday things is mined from the Earth.
NO, in fact, the extreme opposite, he believed standing would make a bigger stand them fighting.
lead would be almost twice bigger. Lead has a density of 11.34 g/ cm3 gold is denser at 19.32 g/cm3
Hi
The Greeks could learn that Greece is not as big as the circumference of the Earth. This would lead to new countries, like America.
If the Sun were to grow bigger, it would enter the red giant phase of its lifecycle, expanding significantly and potentially engulfing the inner planets, including Earth. This expansion would lead to extreme increases in temperature and radiation, making it uninhabitable for any life forms. Eventually, the Sun would shed its outer layers, creating a planetary nebula, while the core would shrink into a white dwarf, gradually cooling over billions of years.
A high mountain made of lead is impossible on Earth because lead is a heavy metal that is not naturally found in large concentrations in mountainous formations. Additionally, lead is not a primary component of Earth's crust, which is composed mainly of lighter materials like silicon and oxygen. The weight and density of lead would also make constructing and supporting a mountain made of lead impractical.
