What is the difference between good ‘seeing’ and good ‘transparency’? Give one condition for each.

Biology
1 answer:
iren [92.7K]3 years ago
6 0

Answer:

Transparency is the <u><em>opacity of the atmosphere</em></u>, or how clear it is. Moisture and humidity lower the transparency, as does smoke or other kinds of pollution. It’s not entirely unlike light pollution in that it washes out the fainter details of astronomical targets. In fact, poor transparency typically makes light pollution worse because it scatters the light around instead of letting it escape into space away from your cameras and optics.

Transparency usually gets better with altitude, because you're looking through less air. That's why high altitudes are prized for observatories and star parties.

Transparency is also usually very good after a rainstorm has come through to clear all of the particulates out of the air. This is reason number one I figured my second friend had it right at the star party.

Seeing, on the other hand, is a measure of <u><em>atmospheric turbulence</em></u>. We know that if we take a photo of a fast-moving subject, such as at a sporting event, with a low shutter speed, we'll get a blurry image. So what happens when you have to take a very long dark-sky photo and the stars are jumping all about due to atmospheric turbulence? That’s right, blurry stars and deep sky objects.

Seeing is typically better in places where the geography is very flat. The air masses moving over the land encounter few obstacles and flow more smoothly (sometimes called a laminar flow). In Florida, the winds coming over the mountains gets all mixed up like a creek flowing over big boulders, which makes for terrible seeing.

The wechsler intelligence scale for children (wisc) is a good indicator of innate "genetic" ability for:
goblinko [34]

Answer:

The wechsler intelligence scale for children (WISC) is a good indicator of innate "genetic" ability for children of six to sixteen years old.

Explanation:

Wechsler Intelligence Scale for Children (WISC) is basically a system of testing IQ of children from six to sixteen years old. This testing was created by David Wechsler, who stated that intelligence is a global quality and it should be reflected in children's verbal as well as non-verbal abilities.

This testing system is used by schools for several purposes:


• To evaluate the performance of kids during placement process.  

• It is also used to evaluate abilities of dis-abled children or  deferentially able children.

• IQ scores from WISC can be used to diagnose the problems of the children such as mental re-tardation or some specific learning dis-ability. It can also be used to determine the problems of the children who face hyperactivity or attention deficiency.


• In addition, the test can also diagnose brain related and neuro-psychological disorder.


Point to remember:

The WISC system is not useful to determine the extreme form of intelligence like IQ below 40 and above 160. Wechsler himself focused on this point many times that test is not adequate for children with IQs of below 70 or above 130. Despite of this fact, people use this test to determine the intelligence of deferentially able children who usually have IQ above 130 that is not very appropriate thing.

<em>Note:</em><em> This answer is very generic based on the statement of the question. If you have some specific options of the questions, please post it again with them or comment. Thank you.</em>

The pH scale measures the acidity of a substance. It is a negative logarithmic scale. A pH of 3 has a hydrogen ion concentration
Hitman42 [59]

Answer:

The correct answer is: a pH 2 solution has a <u>10000 times</u> greater hydrogen ion concentration than a pH 6 solution.

Explanation:

The pH scale is a measurement used to describe the acidity of a solution, and this acidity is given by the concentration of H+ (hydrogen ion) in said substance. A solution with a greater concentration of H+, is more acid than a solution with a smaller concentration of H+ and, therefore, has a lower pH. Given that the pH scale is a negative logarithmic scale, a solution with a pH of 3 has a ten times greater H+ concentration than a solution with a pH of 4.

A pH 2 solution has 10 times more H+ ion concentration than a pH 3 solution, 100 times more H+ ion concentration than a pH 4 solution, 1000 times more H+ ion concentration than a pH 5 solution, and 10000 times more H+ ion concentration than a pH 6 solution.

In terms of environmental economics, the only factions that disagree with each other are environmentalists and economists. True
MatroZZZ [7]

What mineral is the least resistant to weathering?
34kurt

Quartz

Explanation:

Quartz is a framework silicate made up of interlocking SiO₂. It is the most resistant mineral to weathering.

This is based on the Bowen's reaction series of minerals.

From the series;

  • In a given melt, quartz is the last mineral to crystallize out of solution.
  • Olivine is usually the first
  • Quartz being the last does not readily react with other substances.
  • This makes it resistant to agent of weathering.
