<span> Space satellites, laser beams, mirrors</span> are used to calculate the distance a continent has moved in a year.
Therefore, your correct answer would be "all of the above".
The most crucial information would be its atomic number.
Explanation:
The left side of the periodic table has elements that have less number of electrons in the valence shell.
These elements loose electrons easily.These elements appear as metals or metalloids in nature.These are hard solids.Their inter molecular forces are very strong.
The right side of the periodic table has elements that have more number of electrons in the valence shell.
These elements gain electrons easily.These elements appear as non metals most of which are gases.Their inter molecular forces are weak.
Answer:
80%
Explanation:
800 / 1000 = 0.8
Efficiency = 0.8 *100 = 80%
