ceramic tile‚ which least affects the dynamics of a bouncing table tennis ball? Background Information: Table tennis is a ball game that can be played on any reasonably sized‚ flat‚ elevated surface. As is the case in any ball game‚ a crucial criterion to base which material to be used as a playing surface is the bounce of the ball. For any ball game to be fair to both sides‚ the playing surface must be such that the ball bounces back to a height that is as close as possible to the original height

or under pumped balls can be detrimental to performance If you do not have the correct amount of air inside of the ball you could possibly blow a game which could end up costing you millions of dollars if you are a professional‚ and it could just all be because of the amount of air inside of the ball you are using. To test this theory‚ you can use a ball for the most popular and played sport in the world‚ soccer‚ to really see if it affects the sport that much and how far the ball goes due to the

Joshua Cooper Jonathan Cooper Tyler Allrutz 1/16/14 Physics Tennis Ball Inquiry Goal Purpose When received this lab we had to come up with an experiment that would have to involve testing two tennis balls but one of the tennis ball had to be altered in one way. The way we tested the tennis ball was by dropping them from a certain height and seeing how high they bounce back up. We then would make a graph and then see the relationship between the data. Once finding the relationship we can

Chapter 11 – Question 24 (p. 351): At the .05 significance level‚ is the number of units produced on the night shift larger? H0: µ1 ≤ µ2 H1: µ1 > µ2 Z critical value: 1.645 x̄d (µ1): 351 x̄n (µ2): 345 σ^2d: 21 σ^2n: 28 Nd: 54 Nn: 60 Z=(351-345)/SQRT((28^2/60)+(21^2/54))=1.302 Fail to reject the null. Z is less than the critical value; therefore‚ the number of units produced on the night shift is less than the number of units produced on the day shift. Chapter 11 – Question

EXPERIMENT 1: REACTIONS OF ENOLATE IONS WITH CARBONYL GROUPS Aims In this experiment we used two techniques for the reactions of enolate ions with carbonyl groups. One technique used was Doebner reaction and the other technique used was Claisen-Schmidt reaction. Therefore the aim of this experiment is to synthesize trans p-methoxycinnamic acid and to synthesize dibenzalacetone via an aldol condensation reaction between acetone and benzaldehyde. The products would be recrystallized using ethanol

Experiment 2: IDENTIFICATION OF UNKNOWNS BY TLC AND MP IN COMBINATION Introduction: Thin layer chromatography (TLC) is one of the most valuable techniques in organic chemistry. This is a best method of separating and identifying mixtures of two or more compounds. The separation is accomplished by the distribution of the mixture between two phases: one that is stationary and one that is moving or mobile. Chromatography works on the principle that different compounds will have different
