My testable question is an off the ground spike more powerful and faster than a spike that is done on the ground. I will answer this by spiking the volleyball ten times, five times in the air and five times from the ground. I will be ten feet away from the wall and I am going to measure how high it bounces after it touches the ground. I chose this topic because I love volleyball and I wanted to know which position has more force and power. My hypothesis is “If an off the ground spike is made,…

Conclusion The initial hypothesis was rejected. The hypothesis was if the mass of the baseball bat affects the distance the baseball will go, then the heavier the bat is, the further it will travel. The average for the 283.5 gram bat was 49.2 meters. The average distance for the 396.9 gram bat was 52.29 meters. The average distance for the 595.34 gram bat was 50.84 meters. The average distance for the 708.7 gram bat was 45.5 meters. The results mean that the heavier the bat, the less distance…

When they round the brow of the first hill, the force of gravity makes them hurtle energy as well. Even the rattling noise the rollercoaster makes uses up some of its energy. The cars lose more and more of their original energy the longer the ride continues, and, since the cars have no engines, there's no way of replacing it.…

Introduction: Every company wants to improve the quality of their product which in turn will increase the market potential of their product. Food companies are also among those companies those have always tried to develop new ways to provide fresh and healthy foods to their customers. In this process, they have to face some difficulties. These difficulties usually happen in the sorting phase of foods. Everyone knows after the passage of time, every food item loses its freshness. As a result, it…

“To get into the bowl or not to get in the bowl.” That was the question of the hour, as construction on Skittle Hive began, for it landed in the bowl it would be a reward with a glory and honor, not to mention a cool ten points. To do this many things had to be considered, such as elasticity constants, and the energy that was being used. Once that was done the catapult had to be made and tested on angle and how far it could firer. Then it was ready, ready to fire and reach for the skies or maybe…

Scientific Objectives The scientific objectives of the experiment were to measure the temperature of a sample of lauric acid as it 's cooled. The data was manipulated to generate a cooling curve and freezing point. Introduction Matter can be categorized as solid, liquid, or gas this is known as phases of matter. A solid is a sample of matter with a defined volume and a defined shape; this sample is not easily compressible and doesn’t flow smoothly. A liquid has an undefined shape and a fixed…

CHYMOTRYPSIN CATALYSIS Sarkis Hamalian ABSTRACT To examine the enzyme kinetics of chymotrypsin during the catalysis of the synthetic substrate p-nitrophenyl acetate (NPA). Initially, observe the magnitude of the initial burst with regards to the enzyme concentration. Secondly, the analysis of the steady state deacylation rate with regards to the pH of the reaction mixture. Chymotrypsin catalysis is a process that proceeds with two steps, an initial fast step involving the covalent modification…

Projectile Motion Worksheet A ball rolls off a desk at a speed of 3.0 m/s and lands 0.40 seconds later. How far from the base of the desk does the ball land? How high is the desk? What is the speed and angle of impact? A slingshot is used to launch a stone horizontally from the top of a 20.0 meter cliff. The stone lands 36.0 meters away. At what speed was the stone launched? What is the speed and angle of impact? A ball rolls with a speed of 2.0 m/s across a level table that is 1.0 m…

Examples and Solutions Example 1: Given Equation: MnO4- + S2-  Mn2+ + S0 Balance the equation by using the ion-electron method. Step 1 Oxidation: S2-  S0 Reduction: MnO4-  Mn2+ Divide into two half reactions. Identify the element that is being oxidized and the other being reduced. (Use the entire ion or molecule.) Step 2 Oxidation: S2-  S0 Reduction: MnO4-  Mn2+ Balance all the elements (other than oxygen and hydrogen). Step 3 Oxidation: S2-  S0 Reduction: 8H+ + MnO4- …

highly influenced on the reaction rate, when the particle size of the catalyst was decreased, therefore their surface areas was increased and the ratio of catalyst surface and reactant volume was playing a crucial role for controlling the reaction kinetics. The reaction was takes place on the surface of a substance, increasing the surface area should increases the quantity of the substance that is available to react, and will thus increase the rate of the reaction as well. The size and shape of…
