Qualitative analysis is commonly used in a variety of fields, such as law enforcement, the manufacturing of food products, and environmental testing of soil, water and air.

In this assignment, you will research a field of study that interests you and that uses qualitative chemical analysis and create a report about qualitative analysis in that field of study.

a 25 kg child on a 2m long swing is released from rest when the ropes of the swing make an angle of 30 degrees with the vertical. neglecting friction, find the child’s speed at the lowest position. if the actual speed of the child at the lowest position is 2 m/s, what is the mechanical energy lost due to friction?

1)It is predicted that clean water will one day be more valuable than oil. Do you think this is plausible? Why or why not?

1)It is predicted that clean water will one day be more valuable than oil. Do you think this is plausible? Why or why not? Summarize some of the threats to clean water. Contrast this to your local water source. Do you know the source of your drinking water (local river, aquifer, or reservoir?). What are possible contaminates where you live? In your response to another student, compare the water challenges in your area with the ones discussed by another student in his/her post. Does your area suffer from droughts? Floods? Contamination? You might also share an experience where you have had limited water resource and explain what that was like. 

2) Imagine that your city was hit by a major earthquake. What kind of damage would you see? For example, are there dams upstream of your city that might burst and release floodwaters? Are there any major pipelines that would be vulnerable, leading to fires? Are you near a coast? Is there a threat of tsunamis? Do you think your city’s building codes are enough to withstand a major earthquake?

4)In your own words, discuss the geologic history of the area where you live or grew up. Discuss some of the major factors that might have played a role in shaping the local terrain (major rivers, sea-level changes, volcanoes, ancient sea beds, glaciers, earthquakes, etc.). If needed, spend a few minutes researching your state on-line, (search for your state and “geologic history”). Be sure to list all sources that you use in your answer.Based on the descriptions of the other students, respond to a student who lives in a place that you would like to live or visit. What is it about the geology of the place that intrigues you? Be sure to keep the discussion based in science.

Earth science.With the growing number of population in today’s world, the need for clean water is going tobe more valuable than oil. Despite the fact that oil generates the source of income to…

Imagine a thermally insulated container with a gas ofparticles that interact with one another only via the law of gravitation.

Imagine a thermally insulated container with a gas ofparticles that interact with one another only via the law of gravitation. That is, theinteraction energy between any two particles is given by −Gm2 / R , where R is the interparticledistance and G is the gravitational constant. Suppose that the gas is uniforminitially. Describe the future of the gas. Is your answer consistent with the 2nd law ofthermodynamics? (Note: solving this problem may tell you a few things about the earlyUniverse and about how galaxies and solar systems have formed).

Gaseous Movement in a Thermally Insulated ContainerThe movement of the gas particles is random and is solely dependent on the force of gravity; themanner in which the particles interact can be…

In molecular biology,when do you use a scrambled peptide and what is the purpose of doing this?

Scrambled peptides are used in molecular biology and they are constructed by carrying outthe permutation of a peptide sequence which is an original peptide sequence. It has greatpurpose in…

The speed of a transverse wave on a string is 450 m/s, while the wavelength is 0. The amplitude of the wave is 2.

The speed of a transverse wave on a string is 450 m/s, while the wavelength is 0.18-m. The amplitude of the wave is 2.0-mm. How much time is required for a particle of the string to move through a total distance of 1.0-km? Topic: Waves and Sound; The Nature of Waves.
