Why relative retention time used for related substances?
Relative retention time is used for related substances in chromatography because it allows for easy comparison of retention times between different compounds on the same chromatographic system. By expressing retention times relative to a reference compound, such as the main peak of interest, it helps in identifying and quantifying related substances accurately and efficiently.
Why does planets have different time zones?
Planets have different time zones due to their rotation on their axes. As a planet rotates, different regions are exposed to sunlight at different times, causing variations in local time. This is why different regions on Earth have different time zones based on their position relative to the Sun.
Is the air at sea level saturated?
No, the air at sea level is not always saturated. Saturation occurs when the air holds the maximum amount of water vapor it can at a given temperature and pressure, leading to humidity levels of 100%. However, relative humidity at sea level can vary widely depending on environmental conditions, temperature, and weather patterns. Thus, while air can be saturated at sea level, it is not inherently so at all times.
How many stations must compare results to determine the epicenter?
At least three seismic stations are needed to compare results and determine the epicenter of an earthquake using the method of triangulation. By measuring the arrival times of seismic waves at different stations, scientists can pinpoint the epicenter where the waves intersect.
Why are planets seen in different locations at different times?
Because the planets are closer to us so when we look at the planets we can see them move so the closer an object is to you the easier it is to follow its motion. Hope you could use my answer
How a device to measure relative humidity was made in BC times?
A device to measure relative humidity in BC times was done with a simple twig placed parallel to the ground and mounted several feet up. When relative humidity increases, the twig points down, and when it decreases, the twig points up.
What humidity is required to paint acrylic latex?
everything you want....acrylic is great...just use your medium knowing there is no right or wrong....not ever...one love...... Actually, in these type of things, there is a right and wrong. Acrylic house paint should not be applied if the humidity is higher than 85%. Drying times are normally calculated at 50% relative humidity.
How do you use relative ferquency in a sentence?
You wouldn't. First of all, frequency is spelled wrong precluding its use. Second frequency is not relative; it is a constant in time (events/sec). There are not relatively more waves /sec in blue light than in red, there are more, period. Similarly, there are not relatively more of less of anything since this is an exact constant that is relative only if time changes.
Why are constellations seen at different places and time?
Constellations appear to be in different places at different times due to the Earth's rotation on its axis. As the Earth rotates, the position of the observer relative to the stars changes, causing different constellations to become visible. This is why different constellations can be seen in the night sky at different times and in different locations on Earth.
How do you compare King Lear with The Homecoming?
They are very different plays that were written at very different times by very different playwrights and so are virtually incomparable. I think the thing that does compare is the power struggle. I hope this helps but if you added a little more detail in the question and context then I could help more.
How is the humidity in chennai different from that of jaisalmer in thar desert?
Chennai is very humid, often more than Jaisalmer.

In the science fair project do white candles burn faster than colored candles do you have to burn them all at the same time?
no, you can but you dont have to all you have to do is time them and compare the times, so you can do them at different times
How many times is the volume of a triangular prism different form it's surface area?
There is no direct relationship between the two. The ratio depends on the relative measures.
When was petroglyphs made?
There isn't a time on it . Many were done at different times. The only possible way to find the time is to find all petrographic and compare them
Why do constellations change with seasons?
Constellations appear to change with the seasons because Earth's orbit around the sun causes us to see different parts of the night sky during different times of the year. As Earth moves, the position of the stars relative to the sun changes, causing different constellations to become visible at different times.
In what unit do I measure the radius of a star?
You can use kilometers. Or you can compare it to the radius of our Sun, and say, for example, "This star has 600 times the diameter [or radius] of our Sun."
