1. Determine the spring constant‚ k‚ of Spring 1‚ by using Hooke’s Law. Take three different measurements (since 3 masses) and do three calculations and average your k’s to get a more accurate answer. By applying lots of friction‚ you will be able to get your mass to hang still. Show a table of your data and your calculations of k. Spring 1 with three different masses: 50 grams: Spring stretched: 5m F = 50gm * 9.8 m/s2 = 490.00 N K= 490/5m = 98 100 grams: Spring stretched: 10m F = 100gm * 9

My lab group studied the effect of PH on reaction rate/ enzyme activity measured by foam height. PH is the measure of the concentration of hydrogen ions in a solution. The higher the hydrogen ion concentration‚ the lower the pH. Every enzyme has an optimal PH‚ meaning they have a very small window in which they are most active. Our enzyme (potato smoothie) had an optimal PH of 7.0-7.5. We know this because we measured the enzyme’s reaction rate by measuring foam height. The largest foam height we

I have also used it as a homework assignment. Its strength lies in the fact that it paints a picture of actual behavior and then helps the leader see how he or she can redistribute behavior. Activity Description: * Have the participants think about what they actually do on a daily basis. Then ask them to draw generalizations about how they

A businesses success is determined by many factors‚ such as profits gained‚ customer satisfaction‚ employee satisfaction‚ and owner satisfaction. These successes are usually the output result of effective co-operation in the workplace. However‚ there is a certain barrier that hinders the process of good co-operation‚ they are known as “resistance to change.” There are two types of resistance in organizations‚ these are known as functional resistance and dysfunctional resistance.

Extracurricular Activities on Academic Performance at NSU Introduction Music‚ volunteer work‚ community service‚ sports‚ debating‚ etc—all of these have an influence on how university students perform academically. The way students choose to spend their free time can affect their academic performance; it is not simply traditional in-class instruction that impacts academic achievement. “A study by the U. S. Department of Education revealed that students who participate in co-curricular activities are three
