What is the mass of 4.2kg gold when it's transferred to a planet having twice the gravity of earth

Chemistry
1 answer:
rjkz [21]3 years ago
5 0

Answer:

The only relationship is that the larger the mass of an object the more gravitational force it has. So... something that has more mass has more gravity. The mass of 4.2kg of gold when transferred to this new planet is still 4.2kg. However, the WEIGHT (not mass) is now doubled to 8.4kg. Mass is constant it is how much matter something is made up of. Weight depends on the gravitational force. Moreover, I would look at other answers too (I'm not entirely confident of saying that the weight is 8.4kg since I don't have any gravitational equations in front of me it just sounds logical).

Which level of an energy pyramid has the most energy available?
nirvana33 [79]

7. A

The energy pyramid is simply going from the bottom having the most energy, and the top having the least. The most energy in the energy pyramid is provided by the producers. The producers are at the bottom of the energy pyramid. They are the basis of all ecosystems. The producers have the most energy because they are the ones that manage to produce food for themselves, thus they provide 100% energy, while all other levels have 10% of the previous level of the energy pyramid.

8. coyote

The trophic levels are simply divided into autotrophs, which are the ones that produce the food for themselves, primary consumers, which are feeding on the producers, and secondary consumers, which are feeding on the primary consumers. In the category of secondary consumers we have the predators. The predators are the ones that eat the primary consumers, and the coyote is falling into this category. The coyote is a predator, from the canidae family, being a carnivore that preys upon herbivores.

9. True

The invasive species are the species that have managed to reach and inhabit places that are not their native territory. This can happen in a natural way, or because of the humans. The invasive species are usually much more competitive than the native species. They manage to take their food sources, prey upon them with ease, reproduce much quicker, as well as introducing new diseases. All of that results in in easy expansion of the invasive species, while the native species decrease or even go extinct.

10. It would decrease because the greenfly population would decrease

The ladybird, or ladybug, is falling into the category of secondary consumers, thus they are predators. They feed upon small insects, mostly that are considered as pests, such as the greenfly. The greenfly is feeding on the berries. If the berry population starts to decrease, then the greenfly population will decrease as well, as the food source will be smaller. The ladybird population will too start to decrease, as the greenfly population, its prey, will be decreasing because of the decrease in the berry population.
