Answer:
Igneous rock
Explanation:
The rock held by Florian is already a metamorphic rock. On further subjection for heat and pressure, the rock will melt to become igneous rocks.
- A banded rock is termed a gneiss
- In such a rock body, areas concentrating dark minerals and light minerals alternates to form the distinct domains.
- This in turn results from a very high grade metamorphic event.
- In retrospect, if this rock body is further heated, a melt or magma form which is the material by which igneous rocks are derived from.
Answer:
50,000,000 Hz
Explanation:
<em>Rearrange the formula:</em>
wave speed = frequency × wavelength → frequency = wave speed ÷ wavelength
wave speed = 300,000,000m/s
wavelength = 6m
<em>Substitute in the values:</em>
frequency = 300,000,000 ÷ 6
frequency = 50,000,000 Hz
Hope this helps!
