Answer:
Acceleration due to gravity will be .
Explanation:
We can use the gravitational force equation:
The F is equal to the weight of the astronaut, so we will have:
- M(e) is the mass of the earth
- R is the radius of the earth
- G is the gravitational constant
But the distance between the astronaut and the center of the earth is 2R, then we have:
Therefore the acceleration due to gravity will be .

Q mix = Q water
mcΔt sand + mcΔt water = mcΔt water
30.2 x 2.01 x (29.3-12.1) + 87.7 x 4.19 x (29.3-12.1)=m x 4.19 x (85.8-29.3)
1044.07+6320.36=m x 236.74
m = 31.11 g
