Answer:
The answer is D. 5390
Explanation:
A kilogram to newton unit is 1 kg to 9.80665 newtons
If you do 550 times 9.80665 you get roughly 5393.6575 which is the closest to 5390
Weight = mg Mass, m = 8kg, g ≈ 9.8 m/s² on Earth
W = 8*9.8
W ≈ 78.4 N
4.52•10^12 = 4520000000000
or?
4.52•10^12,000,000 = 452 with 12 million zeros minus 2 zeros at the end,
Because 4.52•10^12m doesn’t have a value added to it. But there are your valid answers anyways.
Answer: The answer is that they rely on shock waves that are created by earthquakes and explosions,and that is how they find out the structure of the interior of the planet. :)
The force of gravity will decrease.
More the distance between the objects, less the force of gravity between them.
They are inversely related.
Hope this help :)
