The answer is indeed carbon dating, but let me explain it to you a little bit better: This is so because Carbon dating is the method that has the determination of the age of an organic matter. That is why we can say that that uses a mathematical equation and the half-life of decay to determine the exact date of a fossil. Hope this clarifies everything
Answer:
pH = 7.01
Explanation:
The pH can be calculated using the formula:
pH = -log[H⁺]
In this formula, [H⁺] represents the concentration of H⁺. Since you have been given this value, you can easily find the pH.
pH = -log[H⁺]
pH = -log[9.71 x 10⁻⁸]
pH = 7.01
Energy in wind comes from the sun. for example, when the Earth’s surface absorbs the suns energy, it turns to heat. wind is produced by uneven heating from the earths surface by the sun. Since the earth's surface is made of various land and water formations, it absorbs the sun's radiation unevenly. The blades on the wind turbine move from the wind. i hope that made sense, if it didn’t i’m sorry, i hoped that hep though!
