Of course not , also thanks for the free points :)
Answer:
(a) Slower the sound travel
Explanation:
The speed of sound also depends on the material it is traveling on. The denser the liquid, the slower the sound can travel and the less denser the liquid, the faster the sound can travel. This is because <u><em>denser materials have larger molecules than less denser materials. </em></u>Sound waves travel through "vibration." It takes more energy to vibrate in denser objects than in less denser ones; thus this explains the<u> slow travel rate of sound in a denser medium of liquid.</u>
Minerals are identified according to their properties. One of these properties is their breaking tendency: <em>cleavage</em><em> or </em><em>fracture</em>.<em> Cleavage: Calcite, mica, muscovita, pyroxene. Fracture: Quartz, Asbestos, Limestone.</em>
<u><em>Note</em></u><em>: Since I do not know which your 10 minerals are, I will provide examples of each type according to the breaking tendency.</em>
Many properties of minerals are used to identify them, such as <em>color, density, hardness,</em> among others. In this case, we are talking about their <u>breaking tendency.</u>
<h3 /><h3>How do minerals break?</h3><h3 />
- Minerals can cleave or fracture.
- A type of mineral breaks always in the same, and this is why the breaking tendency is useful to identify them.
<h3 />
<u>- Cleavage</u>
- The mineral breaks in flat smooth planes.
- Cleavage direction and smoothness of surfaces are significant when identifying.
<u>- Fracture</u>
- The mineral break in irregular planes.
- In these minerals, there is no particular breaking direction.
<h2 /><h3>Examples</h3>
<u>- Cleavage</u>
<u>- Fracture</u>
