The intensity or refraction depends on the material
Explanation:
In the experiment, the purpose it to determine the effect of the material on the refraction index. The refraction index is the ration of the incident ray to the refracted ray. This relationship is known as Snell's law of refraction
where i and r are angles of incident an the refracted ray and n is the refractive index. The dense the material, the more the angle bends. This means that the angle of refraction, as measured by the protractor, is going to be large.
Answer:The changes in land use associated with urban development affect flooding in many ways. Removing vegetation and soil, grading the land surface, and constructing drainage networks increase runoff to streams from rainfall and snowmelt.

Q12 LED wont glow att all
Answer:
Adenine pairs with Thymine or Uracil, Cytosine pairs with Gaunine
Explanation:
In DNA it's Adenine and Thymine but once DNA is transferred to RNA during transcription, Thymine turns into Uracil. Cytosine and Gaunine stay the same throughout the process.
Answer:
11.7 g in 1 L of water.
Explanation:
Molarity (M) or Molar concentration is a measure used in chemistry for solutes in a solution.
It is defined as mol/ L (number of moles per litre).
0,2 M means we have 0,2 mol/ L
In order to know how many grams this means we need to look up the molecular weight of the solute. In this case NaCl: 58.443 g/mol
= 
X= 
X= 11.69 g
The solution has 11.69 g of NaCl in 1 L of water since its an adequate polar solvent for NaCl dissolution.
