Answer:
so option 1 is correct
Step-by-step explanation:

power 0 * -2 = 0
if power is 0 then it equals to 1 so
= 1
You can set this up as 2 fractions equal to each other, like ratios.
18/11=108/x
Cross multiply and you get 18x=1,188
Now divide both sides by 18 and get x.
x=66.
If the height of the building is 108ft, the width is 66ft.
F = Gm1m2/r^2 = 6.67 x 10^-11 * 68.5 * 6.43 x 10^23 / (3.43 x 10^6)^2 = 2.93 x 10^15 / 1.18 x 10^13 = 249.7N
The first one would reduce the size because it would now be 4/5 of the actual size
The scale factor 7/2 would enlarge it because it is getting 3 1/2 time larger than the oringanl size
