Sorry if this didn't help- I'm not quite sure what you're asking.
Answer:
The new force becomes (1/9)th of the original force.
Explanation:
The gravitational force between two masses is given by :

Where
r is the distance between masses,
If the new distance is, r' = 3r
The new force is given by :

So, the new force becomes (1/9)th of the original force.
Don't listen to the other guy I just took the test and got it wrong because of him..
I re-took it and the correct answer is
A) Safety Data Sheets (SDS)
The oceanic crust has three layers: layer one, layer two and layer three. The first layer consists of non stratified or semi - stratified sediments. It consists of land sediments. The second layer is divided into two parts - topmost volcanic layer and finely crystallized basalt. The layer is thin in the ocean but gradually increases its width away from the crest. The third layer consists of granulated gabbros and igneous rocks that have low content of silica rocks. Continental crust contains different kinds of granite. Most of the rocks in the crust are silicate and aluminum components that can go about a thickness of 70 kilometers.
