...?Statistical Tests Introduction There is an ample amount of evidence in the literature that heart and body size are correlated3&15. It is believed that individuals with large body size will generally possess a larger heart as opposed to smaller individuals. The cardiovascular system functions by pumping blood to meet the metabolic requirements of the tissues. To fulfil these metabolic requirements it is suggested that the heart rate of smaller individuals should be greater than the heart rate of large people. This theory is based on the concept that a heart with small size will have smaller cardiac output as compared to the larger heart. Hence, this scientific theory proposes that the heart beat of the larger individual will beat... Tests...

...?Lidia M. Lujan Lab report W14s1 Debate on Global Warming: Scientific Basis Global warming refers to the increase in the temperature of the earth's surface and troposphere. The term global warming is used interchangeably with “climate change,” referring to the other climatic changes aside from or due to increased global temperatures. The change in temperature is attributed directly due to increased in emission of greenhouse gases, largest concentration of which is carbon dioxide. The increased emission arises from human activities in the transport and energy sector (US Environmental Protection Agency). Other human activities like clearing of land, deforestation, and desertification that abet temperature...

...Running head: RECYCLING ALUMINUM TO ALUM Recycling Of Used Aluminum Cans to Alum: A Study Affiliation Introduction Aluminum and its alloys find several applications today, right from soda cans to aircraft material. This is because aluminum is versatile and has many desirable properties: light weight, nontoxic, pleasing appearance, ability to take high polish, high electric and thermal conductivities, corrosion resistance, malleability, ductility, non-magnetic, and non-sparking. (Greenwood & Earnshaw, 1997) Aluminum combines with other metals to give alloys with high mechanical and tensile strengths. The abundance of its ore makes aluminum and its alloys easily available - Aluminum comprises 8.3% by weight of the earth’s crust... head:...

...SUMMARY SHEET Physics Laboratory Report -- Equilibrium of a Rigid Body Objective To be able to determine the center of gravity of a rigid body andpositions of weights with reference to that center that would establish equilibrium of forces and torques
Method
Obtain the weight (in Newton) of the meter stick and the average weight of the three meter stick clamps. Balance the meter stick in one of the clamps to determine its center of gravity. Place a clamp on one end of the stick to carry a 100-gram weight and slide the stick through the supporting clamp to locate the balance (position of the axis of rotation). Then place another clamp with a 200-g suspension and repeat the same previous step. Record positions with respect...

... Last 4 digits of ID: 7989 Section: Lab Spring Laboratory 7: Ecological Niche (15 points) Part I: Definitions and Backgroundinformation
1. The niche of an organism is the overall interactions of an organism with other organisms and its range of needs (Properties of microbes).
2. Organisms might compete for food, light, and space.
3. Evolution is the process of gradual development of organisms from simple structures to intricate forms over time. Competition affects the process of evolution in that the organism that is able to compete favorably for the available resources survives and continues to thrive, whereas the organism that cannot compete favorably dies and becomes extinct.

...Lab report Prediction of the Maximum Height Travelled By a Model Rocket The determination of rocket field is useful when in the quest for determining how high a rocket flies, at a given moment. In this lab, the major objective was to predict how high a rocket model could fly once launched. This involved acquiring a model rocket, then launching it to determine the figures for the various variables. Another related objective was to apply equations for basic projectile motion in determining how high a rocket can fly. Since launching the model rocket, this is considered a projectile motion influenced by height of launch pad, gravity and velocity imparted by the engine. Consequently, there...

This lab experiment is relevant to many scenarios in life. When an object travels in the circular motion, its speed is constant which implies that the magnitude of the objects velocity is not changing while the direction changes. On a practical sense, the activity of driving around a curvy road is equivalent to this lab experiment. For a constant speed, tighter curves tend to generate a greater centripetal acceleration provided by the friction between the tires and the road. This can be described as follows: for steady speed, the equation of centripetal force has it that acceleration is indirectly proportional to the radii of the curve. When a car...

.... A normal pendulum with a few modifications can be used to achieve similar objectives. In this case, a zero position for the pendulum is identified. Since many labs are done on tabletops, the table top is assigned to be the zero height (mean) position. If the tabletop is designated the zero position, then the PE of an object is dependent on its relative height from the tabletop. Therefore, by obtaining the mass of the pendulum and its relative height from the table top, the gravitational potential energy can be calculated follow:
PE = mass x relative height x Gravitational pull
= mgh
