#1) Sand grains can be distinguished from silt grain by ____.
Answer: The answer is size. Sand grains are finer than gravel and coarser than silt. Sand is a naturally occurring granular material composed of finely divided rock and mineral particles. Silt is granular material silt particles are larger than clay but smaller than sand particles, whose mineral origin is quartz and feldspar.
Answer:
Organic and traditional farming are fundamentally different in that conventional farming depends on chemical intervention to combat pests and weeds and provide plant nutrition. Organic farming, on the other hand, produces balanced, abundant food by relying on natural concepts such as biodiversity and composting.
To graph this inequality, start with an open dot on -2.
We use an open dot because n is
greater than -2 but n is not equal to -2.
Next we draw an arrow to the right
to represent all numbers greater than -2.
I have graphed this inequality below too.
The graph below is my own work.
This should correspond to the first answer choice.
The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.
<h3>What is the Doppler effect?</h3>
The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.
The wavelength changes with change in the frequency.
<h3>How does the Doppler effect explain the redshift?</h3>
As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.
Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.
