The picture below shows metamorphic rocks on the Earth's surface.
1 answer:
Referring to the attached image below which represents the complete rock cycle, we will find that:
The metamorphic rocks are formed due to heat and pressure applied either on igneous rocks or on sedimentary rocks.
This means that heat and pressure are the main factors in the formation of metamorphic rocks.
Based on the above, the best choice would be:
a. extreme changes in temperature and pressure

Complete Question
A wave is described by y(x,t) = 0.1 sin(3x + 10t), where x is in meters, y is in centimetres and t is in seconds. The angular wave frequency is
Answer:
The value is
Explanation:
From the question we are told that
The equation describing the wave is y(x,t) = 0.1 sin(3x + 10t)
Generally the sinusoidal equation representing the motion of a wave is mathematically represented as
Where w is the angular frequency
Now comparing this equation with that given we see that
