Quadratic equation

Chemical change is any change that results in the formation of new chemical substances. Chemical changes take place on the molecular level. Another way to think of it is that a chemical change accompanies a chemical reaction. To find if a Chemical Change is occurring you need to determine whether a new substance has formed because of the change. If a new substance has been produced, then a chemical change has occurred. The new substance formed in a chemical change could be a solid, liquid or…

The solution of the Frank and Doris race problem looked to be simple at first. Although Doris speed began faster, Frank gained speed and passed her and thus seemed to be the winner of the race. After looking more closely at the problem I discovered this was not quite the case. I first sketched Frank and Doris given values onto the one Velocity-Time graph. Originally looking at this graph, it looks as if Frank passes Doris at 10 seconds, because that is when his speed becomes greater than Doris’s…

Aim: - The aim of this experiment is to find out on how the independent variable which is the temperature changes that reaction rate of the magnesium and hydrochloric acid (HCI). Hypothesis: - As the concentration increases, the rate of reaction increases as well. Variables: - The independent variable is the volume of hydrochloric acid - The dependent variable is variable is the volume of the hydrochloric acid and the duration of reaction. - The controlled variables are length of the strip of…

Mood in the Cold Equations Sometimes, even the most innocent and smallest of mistakes can have a drastic effect on things. Since space is pretty much the full extent of human exploration, small mistakes almost always have a very drastic effect. In the short story “The Cold Equations” by Tom Godwin, he creates an intense and tragic mood, by foreshadowing the inevitability of Marilyn’s death, even when she was innocent and…

When a magnet is in motion near a non-magnetic conductor such as copper and aluminium eddy currents are induced in the conductor, causing a dissipative force called magnetic braking force, or a change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law,…

(2) through transposing Eq (2) The activation energy was found from the following equation E = 8.314 * slope (3) The activation energy values were later used for computing the pre-exponential factors (A) by equation (1). In the meantime, activation energies (Ea) for these energetic compounds were calculated by the Ozawa method. The Ozawa equation according to ASTM E698 is equal to the following…

A rate law is an equation used to determine how much the concentrations of solutions will change as times goes on. In this experiment, the rate changed based on the five degree Celsius temperature change and concentration change in three different reactions. In this lab,…

All the scenes in the play were short and barely any characters were called by name. They also did not go in order of the pamphlet that spells “Shakespeare.” Throughout my paper, I try to describe each scene to the best of my ability with the info of which play they are acting out or about just the scenes in general. The beginning of the play began with people cleaning up the stage with brooms. The three people were slouched over sweeping close together. This showed medium topography and close…

Dulhunty (1977) also found that the extracellular potassium and chloride concentrations could affect the membrane potential in such a way that could be modelled by the GHK equation, depending on the concentration of chloride intracellularly. These results also support the hypothesis and results that the GHK equation, which accounts for the permeability and concentration of several ions across the membrane, may provide a good model for predicting the membrane potential…

rusticus crayfish abdominal muscles, and we ask whether or not the Nernst Equation solely based on [K+] can also predict the cell’s resting membrane potential. We predicted that [K+] concentration had a significant influence on the membrane potential and thus the Nernst Equation was an accurate predictor of the observed Vm changes. Our results indicate that our hypothesis was incorrect- the results indicate that the Nernst equation calculations did not correspond with the observed resting…
