Over a period of 30 days a student studied the night sky and recorded his observations. One night he watched a shooting star streak across the sky. His curiosity led him to list all the possible things it could be, then after researching, analyzing and comparing each, he proposed that which of the following was the most logical identification of a "shooting star? Answer F asteroid G comet H meteor J moon

meteor

Explanation:

The most logical identification of a "shooting star" is a meteor. A meteor is basically any material from outerspace that falls to Earth. The main characteristic of a meteor is that from our point of view on the surface of the Earth it looks like a shooting star because we see a streak of light behind it. This light is simply dust and rock from the meteor burning up as it enters the Earth's atmosphere, leaving a "tail" of light behind it. Which to us looks like a shooting star.

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.
