Positive impact of technology: Technology also has a great impact on all the fundamental aspects of all our cultures including laws and how they are enforced, language, art, health care, mobility, education and religion. For instance the great technological improvements in health care have given a chance to doctors to treat their patients in an environment that is virtual through the use of mediums such […]

A traveling wave on a long string is described by the time-dependent wave function f1(x,t)=a1sin(b1xq1t), with a1 = 5.00 102 m, b1 = 5 m1, and q1 =…

In the figure, the battery has an emf of 12.0 V, the inductance is 2.78 mH, and the capacitance is 9.50 pF. The switch has been set to position a for a long time so that the capacitor is charged. The switch is then thrown to position b, removing the battery from the circuit and connecting the capacitor directly across the inductor. http://d2vlcm61l7u1fs.cloudfront.net/media%2F517%2F51708182-2bb8-4a2f-9b92-8823185610d7%2Fphp9dWUdQ.png f=979345 Hz Qmax=1.14 […]

MICHIGAN**** You have been recently hired as an Epidemiological Research Assistant at your county’s Health Department. It is only day 1 on the job and you have been asked to develop a presentation for the County Commissioners describing a health disparity within your community. In your report, you are asked to summarize the demographical information about the population, as well as summarize the health disparity. […]

Click on the link Mercury Chaser’s Calculator to open a table of Mercury’s maximum elongations. The first person in the team copy, paste, and post the elongation data for a 3-year period (the previous year, current year, and next year) into your team’s discussion forum. In your team’s forum, members work together to examine the 3-year elongation data (posted by the first person) to find two days […]

For the formation of NOCl the rate expression is rate= K[NO]E2x[Cl2] in a volume of 2.0L, 5.0moles of NO and 2 moles of Cl2 were brought together and the initial rate was 2.4E-3 what is the rate constant for the reaction and what will the rate be when one half of Cl2 has reacted Show more

A neutron star has a mass of 2.0 1030 kg (about the mass of our sun) and a radius of 5.4 103 m (about the height of a good-sized mountain). Suppose an object falls from rest near the surface of such a star. How fast would it be moving after it had fallen a distance of 0.016 m? (Assume that the gravitational force is constant […]

1.      What is EM radiation? Explain some key differences between ionizing EM radiation and other forms of EM radiation, giving an example of each. 2.      What are a two different ways that ionizing radiation can hurt people? 3.      What is the linear hypothesis for radiation exposure? Is it used for anything practical? Is it proven? 4.      Suppose you learn that a hospital X ray imaging machine is subjecting patients […]

The Earth is approximately 4.5 billion years old. Life first appeared 3.5 billion years ago with prokaryotic cells. The first eukaryotic cell did not appear until 2.5 billion years ago approximately. We know this because of the fossil record. How did those first eukaryotic cells get here? What are your ideas concerning the evolution of the first eukaryotic cells? Do not concern yourself with how life first formed, rather just concern […]

In an  ____________  solution in animal cells, there is no net movement of water. An animal cell in a  ____________  solution may lyse or burst open. An animal cell in a  ____________  solution will shrivel up or crenate. Plant cells react differently to osmotic changes due to the presence of the  ____________ , a structure that animal cells lack. For a plant cell in a  ____________  solution, vacuoles fill with water,  ____________  turgor pressure. For a plant […]
