A student is given a mineral that she can’t identify. Explain how the techniques Sandra used in the investigation can help the student identify the mineral.

Answers

Answer 1
I mean this is a contextual question as it says “explain how the techniques Sandra used *in the investigation* can help” so this info might not be right because I don’t know if it’s mentioned
But take other minerals that have already been identified and compare lust, texture, malleability, and reflectiveness

Describe two ways you think a sound wave could be stopped or could change change direction.

Answers

Answer:

Like any wave, a sound wave doesn't just stop when it reaches the end of the medium or when it encounters an obstacle in its path. Rather, a sound wave will undergo certain behaviors when it encounters the end of the medium or an obstacle. Possible behaviors include reflection off the obstacle, diffraction around the obstacle, and transmission (accompanied by refraction) into the obstacle or new medium

Answer:When sound waves move from one medium to another, there will be changes to the velocity (or speed), frequency and wavelength of the sound wave. This change in velocity can also result in a change of direction of the sound wave - also known as refraction
