The magnet needs to be held above the coils of wires
Nonmetals usually exist as molecules, combining with atoms of themselves.
Nonmetals can exist on their own as individual atoms.
Metallic elements can exist on their own as individual atoms.
Explanation:
Non-metals usually exists as molecules in which their atoms combines with one another.
Non-metals are capable of covalently bonding with themselves by sharing their electrons and establishing an atomic bond. Metals cannot do this because they prefer to lose their electrons due to the large density of electrons in them. For example O₂, N₂ e.t.c
Non-metals can exist on their own as individual atoms. A stable atom with an octet configuration is generally stable and can exist on its own. A group of non-metals in group 8 can exist on their own. For example Neon gas is an atom of neon, Argon e.t.c
Metallic elements can also exists as individual atoms on their own. They have large sizes and prefers to lose electrons. Gold, Copper, Sodium are some of the metallic elements freely occur as stable individual atoms.

Answer:
The distance between two posts
Explanation:
As the students have already measured the amount of time necessary for the wave to oscillate up and down that is on the string between two posts,They have to measure the speed of the wave.
ie v=fλ
<em>They have to measure distance between the posts.
</em>
Because wavelength is equal to the distance between the posts ie full length of string.
The frequency of the wave is calculated by
f=
1/T
Where is the time period which the students have calculated ie the amount of time taken to oscillate up and down,
Thus the wave speed is calculated using formula
v=λ/T
