Answer:
Texture Gradient
Explanation:
Texture Gradient -
It refers to the disrupted pattern on any uniform surface , is referred to as the texture gradient .
The pattern is somewhat very uniform in nature , i.e. , is constant over a particular area .
The three types of texture gradient are-
- perspective ,
- density and
- distortion of texture elements .
Hence , from the given information of the question ,
The correct answer is texture gradient .
The rate constant : k = 9.2 x 10⁻³ s⁻¹
The half life : t1/2 = 75.3 s
<h3>Further explanation</h3>
Given
Reaction 45% complete in 65 s
Required
The rate constant and the half life
Solution
For first order ln[A]=−kt+ln[A]o
45% complete, 55% remains
A = 0.55
Ao = 1
Input the value :
ln A = -kt + ln Ao
ln 0.55 = -k.65 + ln 1
-0.598=-k.65
k = 9.2 x 10⁻³ s⁻¹
The half life :
t1/2 = (ln 2) / k
t1/2 = 0.693 : 9.2 x 10⁻³
t1/2 = 75.3 s
Answer:
The rock cycle
Explanation:
The three types of rocks are related and connected through the rock cycle. Rocks are not formed independently of one another, the process of their formation are interconnected.
Igneous rocks are made from cooling and solidification of magma. These magma are derived from the melting of rocks that have been subjected to high temperature and pressure.
When igneous rocks are formed, they can follow two path ways. They either get transformed to sedimentary rocks or metamorphic rocks.
When igneous rocks are subjected to metamorphic conditions, their mineralogy is altered to form metamorphic rocks.
If igneous rocks gets weathered and broken down by agents of denudation, they end up getting transformed into sedimentary rocks.
