Answer: Dissolving sugar in water, burning a match, and sawing a board in half

Explanation: Dissolving sugar in water is an example of a physical change. Here's why: A chemical change produces new chemical products. In order for sugar in water to be a chemical change, something new would need to result. A chemical reaction would have to occur.

When a match burns, it undergoes a chemical change. Matches use sulfur, phosphate and a friction agent held together by a binding agent. With a match, heat ignites the phosphorous on the head of the match

cutting of wood is a physical change because only physical property of wood is changed and no new substance is formed. the properties of wood remains the same. burning of wood is a chemical change as new substances are formed that is smokes and CO2. it is different from wood.

I hope this is the correct answer im pretty sure because I've finished that quiz or test already

Which of the following has to happen before the eardrum begins to vibrate with the same frequency as the source of the sound wav
djverab [1.8K]

Answer:

C. The outer ear has to collect the sound waves and lead them to the middle ear.

Explanation:

In the process of hearing, the first thing that happens is that sound waves enter the outer ear through a passage called "auditory canal" that reaches the eardrum.

The movement of the incoming sound waves causes the eardrum to vibrate and transmit these vibrations to three tiny bones of the middle ear.
