Answer:
The force of gravity after you double the mass and the distance is half of the initial force: 
Explanation:
The initial force of gravity is:

where
is the universal gravitational constant,
is the mass of the first object,
is the mass of the second object, and
is the distance between the objects.
If the mass of the second object is doubled, now we have
, and if the distance between the objects is also doubled instead of
now we have
.
So the force of gravity now is:

and we know that 
so the new force of gravity is:

The force of gravity after you double the mass and the distance is half of the initial force.
Answer:
-7.44°C
Explanation:
Calculate the molality of the solution. Use the density of the solvent(water) as a conversion factor in order to convert from millilitres of solvent to grams of solvent. Then convert grams into kilograms. Finally, use the molar mass of ethylene glycol as a conversion factor to convert from grams to moles of ethylene glycol.
m = 25.4 g C2H6O2/89.0 mL solv
= 4.6321 C10H8O
Compute the freezing-point depression.
ΔT_f=K_f*m ==> (1.86°C)*(3.9996 m)
=7.44°C
Compute the freezing point of the solution by subtracting the freezing-point depression to the freezing point of the pure solvent.
freezing point =0.0°C-ΔT_f
= -7.44°C

I to have no clue as well
I don’t know I think about 20 meters but I’m probably wrong I just need to do this so someone can answer my question
