Quartz is an important mineral in mafic rocks like basalt and gabbro. The given statement is false.
<h3>What is mafic rocks?</h3>
Mafic minerals and rocks are silicate minerals or igneous rocks that are high in magnesium and iron.
The majority of mafic minerals are darker in color, and some of the most common rock-forming mafic minerals are olivine, pyroxene, amphibole, and biotite. Basalt, diabase, and gabbro are examples of common mafic rocks.

Answer:
Focal length is 6.67 cm.
Explanation:
Object distance, u, from the lens = 10 cm
Image distance, v, to the lens = 10 cm + 10 cm
= 20 cm
Apply the lens formula to determine the focal length, f, of the lens.
= 
+ 
= 
+ 
= 
= 
Find the inverse of both sides, so that;
f = 
= 6.67
f = 6.67 cm
The focal length of the lens is 6.67 cm.
Both involve gaining a positive effect from a source which becomes harmed.
