Answer:
8) 45 volt
9) 8 ohms
100 volt
Explanation:
using ohms law all through
8) v = 3×15
9) R= 120/15
the last V=100×1
Loudness of the sound depends on the "Amplitude" as loudness is different for two waves, their Amplitude must be different
In short, Your Answer would be "Amplitude"
Hope this helps!

Answer:
Aqueous layer (1 M HCI)
Explanation:
First of us I want to remind you of the cliché in chemistry that like dissolves like. In solvent extraction, a mixture is dissolved in a system consisting of two immiscible solvents. One layer is organic while the other layer is aqueous.
Polar substances partition in the aqueous layer while nonpolar substances partition in the organic layer.
Since Copper sulfate is ionic, we will find it in the aqueous layer according to the old chemistry cliche.
