A simulation that shows how the space shuttle docks with another craft would be which type of model?
A. Conceptual
B. Physical
C. Computer
D. Mathematical

the statement is true

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.

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.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
