D. mechanical energy is transformed into sound energy.
I think the correct answer from the choices listed above would be the last option. It is the chemicals in the core of the star that cannot be determined from the spectrum of a star. Spectrum shows the different classification of the stars depending on their spectral characteristics. It usually involves the light, the wavelength and the distance.
Answer:
<h3>The answer is 0.115 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
![volume = \frac{mass}{density} \\](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7Bmass%7D%7Bdensity%7D%20%5C%5C)
From the question
mass = 10 g
density = 87 g/ml
We have
![volume = \frac{10}{87} \\ = 0.114942528...](https://tex.z-dn.net/?f=volume%20%3D%20%20%5Cfrac%7B10%7D%7B87%7D%20%20%5C%5C%20%20%3D%200.114942528...)
We have the final answer as
<h3>0.115 mL</h3>
