So we need to find the square root of 121. so in the first box, you put 121. Now what number multiplied times itself equals 121? 10 x 10 = 100, and 12 x 12 = 144. So 121 is 11 x 11. 11 goes in the 2nd box.
Answer:
The astronaut must be at 1600 km from the earth to weight 64lb
Step-by-step explanation:
As the weight of an object varies inversely as the square of the distance from the center of the earth, that means that:
weight = k / distance² <em>(1)</em>
Where k is proportionality constant
Replacing:
100 lb = k/(6400km)²
100lb × 6400km² = k = 4,096x10⁹ lbkm²
Now, using (1):
64 lb = 4,096x10⁹ lbkm² / x²
x² = 4,096x10⁹ lbkm² / 64lb
x² = 6,4x10⁷ km²
x = √6,4x10⁷ km²
x = 8000 km
Distance from the center of the earth is 8000 km. Distance from the earth (At sea level):
8000km - 6400km =<em> 1600km</em>
I hope it helps!
