Answer: See explanation
Explanation:
The explanation for why solid sodium chloride can't conduct electricity while molten sodium chloride can is explained below:
Ionic compounds that are in their solid state like sodium chloride have their ions fixed in position. Due to this reason, the able to move, therefore we can say that the solid ionic compounds cannot be able to conduct electricity.
On the other hand, ionic compounds in their molten state, are free to flow unlike when they're in their solid state and therefore we can say that molten sodium chloride can be able to conduct electricity.

Answer:
Because of the revolution of the moon about the earth.
Explanation:
The moon is the natural satellite of the earth; which rotates about its axes and orbits around the earth. As the moon orbits the earth with respect to time, it would complete a revolution in 27.3 days.
During revolution, different phases of the moon can be observed by someone on the earth. This is due to its location at different time during the process. Therefore, Jorge was able to see different phases of the moon because of its revolution about the earth.
If the half life is 5800 years, and there was only 1/4 of the Carbon 14 left in the wood remains, then 1/2 of the 1/2 life or 1/4 is 2900 years so the total age of the wood should be 5800 + 2900 = 8700 years old. We found some ancient highly compressed and water logged wood branches in an old glacial lake in the Highland Valley of BC., Canada and the lake deposits were up to 40,000 yrs old or just past the limit of Carbon 14 dating.
