Options:
- The impact of Earth’s gravity on the decay rate of deuterium is the same as the impact of microgravity.
- Most of the water that forms the oceans of Earth arrived by way of impacts with Kuiper Belt comets.
- Most comets formed from deuterium-based water that was stripped away from early Earth by solar radiation.
Answer:
<u>Most of the water that forms the oceans of Earth arrived by way of impacts with Kuiper Belt comets.</u>
Explanation:
Note, a comet is a celestial body made of ice which releases gases when it orbits close to the Sun. Deuterium is a type of element which can be found in comets and in our oceans on earth. Deuterium is considered an isotope of hydrogen.
Hence, because of the similarities between the Deuterium and Hydrogen, some scientists promote the theory that most of the water that forms on oceans of the earth<em> likely</em> arrived by the impact with Kuiper Belt comets.
The chemical reaction causes electricity to flow through the terminals to the load attached. Some of the acid in the battery remains on the plates as it flows through. When the battery is recharged the acid is returned to the liquid solution to provide more power later.
These are NOT a form of ionising radiation:
- lower ultraviolet radiation
- UV
- visible light (and laser light)
- infrared
- microwaves
- radio waves
