-0.5m/s^2
Explanation:
the answer is negative this only show direction that is acceleration is a vector quantity
The correct answer is option A, that is, placer deposits.
The concentration of heavy deposits known as the placer deposits are produced by the gravitational action, generally found in streams. The minerals that take place as placer deposits comprise copper, gold, magnetite, cassiterite, and copper.
The formation of placer deposits takes place when the metal-bearing rock on land is weathered and the generated debris is washed down to the sea by the rivers. Further by the action of waves, currents, and rides the particles of heavy metal gets amassed to produce mineral sand deposits. These generally occur as beach deposits.
Nature is genes. Nurture is how someone or something is grown/ raised. Scientists believe both are important, so they do not choose one over the other.
I hope this helps.
Answer:
If the hydronium concentration increases, the pH decreases, causing the solution to become more acidic. This happens when an acid is introduced. As H+ ions dissociate from the acid and bond with water, they form hydronium ions, thus increasing the hydronium concentration of the solution.
Its D, because i had this problem on a test, and of course i figured out the answer the hard way... lol
