Lab: investigating hooked law with springs Purpose: to find spring constants of different springs using the slope of a graph of change in heights vs. the weight force. Also‚ to be able to understand how spring constants change when you add springs in a series or paralle Pre lab predictions: We predicted that the graph of gravitational force (mg) as a function of stretch (delta x) would look like Data: Spring #1: y = 8.2941x + 0.0685 This table represents the different distances that

From an industrial point of view‚ the uniform distribution (i.e.‚ the gas distributed homogeneously over the entire cross-sectional area of the column) is essential to achieve optimal reactor performance. For instance‚ high quality and efficiency of the chemical reaction can only be achieved through homogenous gas holdup distribution along liquid phase as in bubble column or slurry phase (liquid-catalyst) in a slurry bubble column due to this homogenous gas holdup distribution lead to better interaction

An analysis of the song by Lady Gaga called “Til it Happens to You” reveals the “aftermath of [the] trauma” of a sexual violence attack as well it reveals how society as a whole views the victims of this heinous and underrated crime. There are three levels on which to analyze the song. The three categories being: what the song is about‚ what the song is saying on an analytical level‚ and what the song is being applied to and used for. The song “‘Til It Happens to You’ is a rock ballad” by the internationally

I. Soil-Transmitted Helminthiasis Parasitism is a symbiotic relationship in which one organism‚ the parasite‚ benefits at the expense of the other‚ the host. Soil-transmitted helminthiasis is a human infection of the intestinal tract caused by different species of parasitic worms acquired through contact with contaminated soil (Bethony et al. 2006). Light helminth infections are well endured by human hosts and usually have no symptoms‚ but some serious cases cause morbidity and mortality (CDC‚ 2013;

population live 500 metres above the sea level‚ this is actually fairly high up. What we might have been thinking of are the mountainous areas of the world like the Andes‚ Nepal or the Himalayas‚ these areas are sparsely populated due to the poor soils‚ low temperatures and high rainfall. Lowlands on the other hand are much more amiable‚ the land is easily farmed and easy to build on‚ much more appropriate for settlement; there are also higher temperatures and potentially less rainfall.

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

Recommended Methods for Determining Soil Cation Exchange Capacity Donald S. Ross and Quirine Ketterings The cation exchange capacity (CEC) of a soil is a measure of the quantity of negatively charged sites on soil surfaces that can retain positively charged ions (cations) such as calcium (Ca2+)‚ magnesium (Mg2+)‚ and potassium (K+)‚ by electrostatic forces. Cations retained electrostatically are easily exchangeable with cations in the soil solution so a soil with a higher CEC has a greater capacity
