help solve number 2

Oceanic CO2  

Cold temperatures from the ocean dissolves CO2 and stores it into deep waters.  

Marine Plants/algae  

Plants and Algae go through Photosynthesis  

Sediments  

Plants and Algae sink to the bottom of the ocean building up large amounts of carbon.  

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

explanation:

the universal gravitation equation. since the gravitational force is directly proportional to the mass of both interacting objects, more massive objects will attract each other with a greater gravitational force. if the mass of one of the objects is doubled, then the force of gravity between them is doubled.
