Which of these is a metamorphic rock?<br> A basalt<br> B granite<br> C limestone<br> D slate
OlgaM077 [116]

Answer:

B:GRANITE

Explanation:

<em>Granite is typical of a larger family of granitic rocks that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals.</em>

These properties have made granite a widespread construction stone throughout human history.</em>

According to Newton's Second Law of Motion, when an object is acted on by an unbalanced force, how will that object respond?
marissa [1.9K]
Newton's Second Law states:
The acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to the mass of the object.

since the net force and the acceleration ar directly proportional, as the net force increases the acceleration will increase.

hope this helps :)
