Answer: Option (2) is the correct answer.
Explanation:
It is known that tap water acts as an electrolyte because there are a number of ions present in it. As electricity is the flow of ions or electrons therefore, a solution which contains the ions is able to conduct electricity.
For example, ions present in tap water are , , etc.
Thus, we can conclude that tap water conducts electricity because tap water has many ions dissolved in it, which are responsible for the conduction of electricity.

Answer: #.37 times greater
Explanation: Volume of a sphere is: V = ·π·r³
Since it is given the diameter of the basketball and the softball, their ratios are r₁ = 3in and r₂ = 2in, in which index 1 represents the basketball and index 2, the softball.
Calculating the volume of basketball:
V₁ = . 3.14 . 3³
V₁ = 113.04 in³
Calculating the volume of softball:
V₂ = . 3.14 . 2³
V₂ = 33.5 in³
Comparing one volume with the other:
= = 3.37
We have that V₁ = 3.37V₂
This means the volume of a basketball is 3.37 times greater than the volume of a softball.
Answer:
SOUND WAVES enter the ear canal and cause the eardrum to vibrate. VIBRATIONS pass through 3 connected bones in the middle ear. This motion SETS FLUID MOVING in the inner ear. ... In the brain, these impulses are CONVERTED into what we "hear" as sound.
