kx is the spring constant times the distance‚ we can mathematically isolate for the spring constant k. We can also graph the data collected and the slope of the line will reflect the spring constant. In the second part of the lab we used the equation T=2πmk‚ where T is the period of the spring. After calculating and graphing the data the x-intercept represented k‚ the spring constant. The spring constant is technically the measure of elasticity of the spring. Data: mass of weight | displacement

Magnetic Fields PHY 114 Lab Report 10/23/2013 Abstract: The purpose of this experiment was to surrounding a magnet there is a magnetic field. The magnetic field is analogous to the electric field that exists in the space around electric charges. Like the electric field‚ the magnetic field has both a magnitude and a direction. The direction of the magnetic field at any point in space is the direction indicated by the north pole of a small compass needle placed at that point. Since electric

The indifference curves will consist of parallel lines with the negative slope m‚ where m > 0. a) How does the marginal rate of substitution between current and future consumption relate to the geometry (i.e. the slope and the intercept) of the consumer’s indifference curves? b) Given perfect substitutes‚ is more preferred to less? Do these preferences satisfy the diminishing marginal rate of substitution

Industrial Economics Term Paper First Draft A manager has to make demand analysis‚ anticipate time value of money‚ detemine supply and demand levels‚ create a goal for his/her firm and understand the importance of profits‚ use his/her company’s products’ elsaticity tendencies before produce them in large quantities‚ maximize it’s profits and minimize production costs. A firm can be merge with another one because of profit maximization target and minimizing it’s cost. Experiences are also important

Is There A Relationship Between Body Temperature and Heart Rate? Statement of Research Question: This study sets out to determine whether there exists a difference in the average body temperature between males and females. Furthermore‚ the study aims to determine whether an increase in heart rate corresponds with an increase in body temperature. Data Collection: The data was obtained from the article “What’s Normal? -- Temperature‚ Gender‚ and Heart Rate” (Shoemaker‚ Allen 1996) as found in
