Which of these would produce a soft sound A (a slow vibration) B (a big vibration) C (a fast vibration) or D (a tiny vibration)

A slow vibration

Explanation:

Hard and soft refer to how much a sound vibrates. When a sound is hard the vocal cords come together and release producing a less resonant sound. In a soft sound, the vocal cords rub together creating friction and heat that results in a more resonant sound.

pure water does not conduct electricity very well. however, when certain substances are dissolved in water, the solution does conduct electricity. you can make a simple device that shows how well a solution conducts electricity. this device uses a flashlight bulb to indicate how well the solution conducts electricity. the better the solution conducts electricity, the brighter the bulb will glow.
