Positive (+) 1.00 is the strongest or perfect positive relationship and indicates that variables change together, either increasing or decreasing simultaneously. Negative (–) 1.00 is the strongest or perfect negative relationship and indicates that variables change in opposite directions: as one variable increases another variable decreases. 3. Describe the direction of the relationship between the Hamstring strength index 60/s and the Shuttle run test. The relationship between Hamstring strength index 60 degree/s and the Shuttle run test is a negative relationship due to r moves away from zero in negative direction and r = −0.149, the strength of this negative relationships would be weak with r -0.5 r=-0.528**, is more significant since p =0.002< 0.01, where r = −0.498** is significant at p =0.004< 0.01.
PK-S Lab 03 – Lab Report Name: ____________________ Section: ___________________ EXPERIMENT 3: Trigonometric Measurements Procedures: 1. Experimental measurement of the angles and sides of a right triangle: A. Create a triangle by taping a string against a wall and taping the bottom of the string to the floor or a table set against the wall. Make sure that the wall is perpendicular to the floor or table by measuring angle C, which should be 90o. B.
The slow oxidative fibers are set up to help with weaker amount of force but are very resistant to fatigue. Then the stronger motor units, although less resistant to fatigue are next, if more force is needed. 9. Restate your predictions that were correct and give data from your experiment that support them. Restate your predictions that were not correct and correct them, giving with supporting data from your experiment that supports your corrections.
Fiber Advantages The following advantages of fiber over other cabling systems are: (Oliviero 250) Immunity to electromagnetic interference (EMI), higher data rates, longer maximum distances, and better security. With copper cabling there is one common cabling problem they are susceptible to EMI. EMI is a stray electromagnetism that interferes with the signal. All electrical cables generate a magnetic field around their central axis. If you pass a metal conductor through a magnetic field an electrical field is generated in that conductor.
This explanation can be demonstrated in table 3 also because the results of the reactions demonstrates that chloride reacted more by the color of the product compared to the color of chloride in the mineral oil. Also it also demonstrates that iodine is the weakest oxidizing agent because the results show that iodide didn’t change much from the color that it showed in the mineral oil. In example 6 we have shown the activity series for the halogens used in this
Lab: 3/28/2014 Acceleration of the air hockey punk Background information Pulley system is a device that is made of grooved wheels. It is a popular tool that uses to help people to lift up heavy objects with a simple structure; rope and a wheel. The design of the pulley is base on Newton's second law( if the net force is not balance ,the object accelerates in the direction of the net force). The pulley system that was used in this experiment. The weight was tightened at the end of a rope, during it is dropping toward the grand, there is a acceleration due to gravity; as a result net force of the punk was not zero( equal the force of gravity), it accelerated and moved toward
These conditions are more suitable for ionic bonds. That is why the sucrose and salicylic acid did not have good results, because they have covalent bonds. There were a few sources of error that could be improved in the experiment. For example, when the substance was poured into the test tubes, some of the compound remained stuck to the weighing paper. If we used a stick resistant material for this step, the whole 1g would be accounted for.
A) is neutralized by water B) is surrounded by water molecules C) reacts and forms a covalent bond to water D) aggregates with other molecules or ions to form a micelle in water Answer: B Page Ref: Section 3 11 9) Which would you expect to be most soluble in water? A) I B) II C) III D) IV Answer: A Page Ref: Section 3 10) Solutes diffuse more slowly in cytoplasm than in water because of A) the higher viscosity of water. B) the higher heat of vaporization of water. C) the presence of many crowded molecules in the cytoplasm. D) the absence of charged molecules inside cells.
This make each time the exact same. In Exercise 4A, Carotene has the greatest Rf because it traveled the farthest. The factors that were involved in the separation of the pigments were the solubility. The Rf of a pigment would not be the same if a different solvent were used because a solvent would have a different solvent rate. The reaction center contains chlorophyll a.
The skill performances such as the passing ability, defensive ability and dibbling were used as the independent variable. Speed, power, agility, cardio-respiratory endurance flexibility was used as the motor fitness variable. Both independent and motor fitness variable were tested by a series of different test. The result shown that defensive ability had positive correlation with speed and agility whereas explosive power, cardio-respiratory endurance, and flexibility had a negative correlation. The passing ability had a negative correlation with speed & agility and a positive correlation with explosive power, cardio respiratory endurance, and flexibility.
