A 400-kg space probe has a weight of 3,560 N on one of the above planets. According to the table above, on which planet is the space probe? Show your work.

Venus

Explanation:

To know the correct answer to the question, we shall determine the weight of the space probe on each planet to see which will correspond to 3560 N.

This is illustrated below:

For Mercury:

Mass = 400 Kg

Gravitational force = 3.7 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 3.7

Weight = 1480 N

For Venus:

Mass = 400 Kg

Gravitational force = 8.9 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 8.9

Weight = 3560 N

For Earth:

Mass = 400 Kg

Gravitational force = 9.8 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 9.8

Weight = 3920 N

For Neptune:

Mass = 400 Kg

Gravitational force = 11 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 11

Weight = 4400 N

For Jupiter:

Mass = 400 Kg

Gravitational force = 23.1 N/Kg

Weight =?

Weight = mass × gravitational force

Weight = 400 × 23.1

Weight = 9240 N

SUMMARY:

Planet >>>>>> Weight

Mercury >>>> 1480 N

Venus >>>>>> 3560 N

Earth >>>>>>> 3920 N

Neptune >>>> 4400 N

Jupiter >>>>>> 9240 N

From the above calculations, we can see that the weight of the space probe (i.e 3560 N) correspond to the weight on venus (i.e 3560 N)

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

bacteria that live on the ocean floor are sustained by phytoplankton. phytoplankton, microscopic marine photosynthetic organisms, have a vastly significant role to play not only in the marine food web of which they’re part of, but also on a more global scale. despite their infinitely small size in comparison to other marine organisms, these tiny creatures occupy an immensely important ecological niche: they are the foundation of the marine food web, and as primary producers, play key roles in supporting all other organisms in the marine environment, as well as in the regulation of the earth’s climate through the sequestration of carbon, oxygen production, and other related processes. phytoplankton account for roughly half of all global primary productivity; therefore, their significance extends far beyond the marine environment alone. there is an intriguing sense of irony in the realization that these tiny living beings that often live out their existence unnoticed and undetected by the rest of the world, have such a far-reaching impact on the lives of virtually all other living organisms on the planet, particularly on those in the marine environment. the world that we have become accustomed to has been and is continuously shaped by the workings of these miniscule yet vital “plants of the sea”.

hope this !
