...D. Specific Gravity * Procedure: I borrowed a refractometer from the counter and held it in a horizontal position and placed a small amount of urine on the capsule with the support of a dropper, then I looked into the scope of the refractometer to see the measurement of the specific gravity of the urine sample. * After doing the experiment, I threw the urine in the toilet and cleaned the container that I used to put the urine Objectives: -To find the specific gravity of the urine sample Result: The specific gravity of the urine is 1.032 which tells us that the specific gravity of the urine is normal Study Guide Questions: 1. What is the specific gravity of normal urine? What factors can cause a deviation from the normal range? The normal range of specific gravity of urine should be 1.000-1.035. But, there are several cases in which if the measurement of the specific gravity of urine may exceed or may fall behind the average value, which may lead to minimal or severe cases, below are the cases of an irregular measurement of specific gravity: If the specific gravity of urine exceeds, there are possible cases of: -Dehydration, addisons disease, diarrhea, heart failure,renal arterial stenosis, shock, SIADH Meanwhile, if the specific gravity of urine falls behind the average value, there are possible cases of: -aldosteronism, excessive fluid intake, diabetes, kidney failure, renal tubular necrosis, severe kidney ...

...This is a video that is presented by Morgan Freeman in Through the Wormhole discussing and debating on different theories on whether or not gravity is real. In physics, the term gravity is well defined as the force that attracts a body toward the center of the earth, or toward any other physical body having mass; the force of attraction by which terrestrial bodies tend to fall toward the center of the earth. In addition the video starts to state that the gravitational pull of the sun keeps the earth from flying off into space and earth's gravity keeps us from flying off the ground. Can you imagine what it would be for living things if it weren't for gravity? The reasonable and obvious answer would be that everything and everyone...

...written in free verse style with little to no alliterations, similes, or any other literary device. The author begins with describing some sort of “power” that we can also assume is gravity and later on when he mentions gravity in a warning sign. The author refers to gravity as her and she. In the first five stanzas, the author talks about the wonders of gravity and the beauty she holds compared to the other forces of the earth, like lightning, tornadoes, hurricanes, and other natural disasters. Then the poem shifts to more somber tone when referring to what would happen without gravity and perhaps taking advantage of it. In the last stanza of the poem, the author provides a setting for the readers, a tennis court on an August day....

...What is a Projectile? In Unit 1 of the Physics Classroom Tutorial, we learned a variety of means to describe the 1-dimensional motion of objects. In Unit 2 of the Physics Classroom Tutorial, we learned how Newton's laws help to explain the motion (and specifically, the changes in the state of motion) of objects that are either at rest or moving in 1-dimension. Now in this unit we will apply both kinematic principles and Newton's laws of motion to understand and explain the motion of objects moving in two dimensions. The most common example of an object that is moving in two dimensions is a projectile. Thus, Lesson 2 of this unit is devoted to understanding the motion of projectiles. A projectile is an object upon which the only force acting is gravity. There are a variety of examples of projectiles. An object dropped from rest is a projectile (provided that the influence of air resistance is negligible). An object that is thrown vertically upward is also a projectile (provided that the influence of air resistance is negligible). And an object which is thrown upward at an angle to the horizontal is also a projectile (provided that the influence of air resistance is negligible). A projectile is any object that once projected or dropped continues in motion by its own inertia and is influenced only by the downward force of gravity. By definition, a projectile has a single force that acts upon it - the force of gravity. If there were any other force acting upon an object, then...

...Gravity is a natural force of attraction created by a large object, such as the Earth, that tends to draw all material towards the center of the mass. The dangers of space are often thought to be associated with the sub zero temperatures, poisonous radiation, technological malfunctions, and this list continues. However, no one ever thinks of the threat that happens directly within the body, that is immediate bone deterioration, and muscle atrophy due to the presence of anti-gravity. Currently, NASA invests millions of dollars in research in order to figure out exactly what happens to both bones and muscles when experiencing zero gravity (Barry). The top researches in the field of life sciences have been spending the last 50 years rigorously testing both humans and animals and the effects that anti-gravity have on their bones and muscles. Very significant results have come from all of the research, and scientists are now looking for different ways to mitigate bone and muscle loss in space. A ‘cure’ for detrimental bone and muscle loss is crucial if humans wish to travel within our galaxy, for example to Mars, as these missions would involve astronauts being exposed to anti-gravity for years at a time. Currently, there are multiple solutions to bone and muscle loss, such as weight bearing exercise, and nutrient supplementation, however nothing has been perfected yet. If the human race wishes to continue to explore space within our galaxy, and hopefully one day outside of...

...Introduction Scientific understanding of gravity, and its effects, has changed substantially over time. Prior to the late 17th century, people believed that matter was seeking its rightful place in the universe. The ancients believed that the center of the universe must be the Earth, therefore, the denser the object, or matter, it would fall; the lighter the matter, the more it would rise. This is what they believed to be the natural order of things. The ancient Greek philosopher Aristotle believed that the bigger and object, the faster it would fall to the ground. Several centuries later, a man named Galileo proved that items fell at the same rate, regardless of mass. Galileo discovered the rate of acceleration. These two thinkers from...

...Geometric Gravity George Gabriel Geometric Gravity Science, the never ending pursuit of answers, it has solved many questions thought unsolvable. It has made the impossible possible time and time again. Yet one question has stood the test of time and to this day remains unanswered. How to unite gravity with the unified field theory or UFT. But to answer that question other questions must first be asked such as, what makes gravity? Scientifically what makes gravity is unknown, gravity is just this mysterious force that exerts itself on universal and atomic scales. We understand what it does but we don’t understand what makes it happen. Throughout my studies I have come across a consistent that I believe needs to be examined and that is, not only a correlation between the geometric patterns found in multi-year planetary orbits and those found when studying Cymatics but also the correlation of those to the orbital patterns of electrons around their nucleus on the atomic level. You may be asking yourself what exactly is Cymatics, or even perhaps what is this lunatic talking about? To begin to answer these questions I will describe Cymatics first. Cymatics is the study of visible sound and vibration, a subset of modal phenomena. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid. Different patterns emerge in the exitatory medium depending on...

...weak surface gravity, an ultracompact neutron star with extremely high surface gravity, and a black hole are described. Concepts such as multiple imaging, red- and blue-shifting, conservation of surface brightness, the photon sphere, and the existence of multiple Einstein rings are discussed in terms of what the viewer would see. Computer generated, general relativistically correct illustrations highlighting the distortion effects are presented and discussed. A short movie (VHS) depicting many of these effects is available to those interested free of charge. I. BACKGROUND It is impossible for a human to travel very near a high gravity star which has a mass like that of the Sun. If, somehow, a person could survive the extremely harmful radiation that would be emitted on or near these objects, the high gravity itself would likely pose insurmountable problems. The person could not stand casually on the surface of such a star because the high surface gravity would tend to flatten them. (Lying down wouldn't help.) Were a person to orbit the star in a spaceship, however, the immense gravitational field would be overcome by a large outward centrifugal acceleration.[1] The problem in this case, however, is the extreme change in gravity between the head and toe of the person, the extreme tidal pull, would surely prove much more than annoying for any human[2]. Nevertheless it is informative and interesting to wonder what it would look like to visit such a high gravity environment...

... Gravitational Lab Go http://phet.colorado.edu/simulations/sims.php?sim=My_Solar_System and click on Run Now. I After the simulation loads click Start. Describe what you see in this simple sun-planet system. Specifically, what happens to the central object (the Sun)? Can you explain why the central object moves? HINT: Is gravitational attraction only the sun pulling on the planet? Does the planet orbit in a perfect circle? Is the sun at the center? In the simplest sun-planet system the Sun has a much larger mass (20X) than the planet. The planet is orbiting around the Sun in an elliptical orbit. The reason for this elliptical orbit is because gravity force of the bodies is acting on each other. The Sun's gravity keeps the planet from traveling off into space, and the planet's gravity acts on the much more massive sun causing it to have its own circular path instead of being just a stationary point. Mathematically, the force of gravity can be expressed as Force= G*(ml*m2/rA2), where G is the gravitational constant, ml is the mass of one object, m2 is the mass of a second object, and r is the distant between the two objects.

Valena, Keena Wong, Monika Yu, Princess Dianne Mei Group 8 SPECIFIC GRAVITY OF SOLIDS AND LIQUIDS Experiment No. 3 Abstract: Questions and Problems 1. Differentiate specific gravity and density. Answer: Density is the measure of the amount of mass per volume of a given substance. Density can be expressed using the equation: ρ=mv Specific Gravity is the measure of the measure of density relative to the density of a reference substance. (ex. Water) In can be expressed using the equation: S.G. =ρ sub.ρ water=m ofsusbtancev of substancem of waterv of water If, Vsub=Vwater then, S.G. =MsubMwater 2.

...Lucius Gardner Mrs. Henry AP Physics 16 February 2016 Gravity Research Project Over the past several hundred years there have been many great scientists that have come up with significant ideas and theories in the scientific field of gravitational research. These scientists include but are not limited to Aristotle, Galileo, Kepler, Newton and Einstein! Each one of these scientist have come along after another, using each other’s ideas to further expand the human species’ knowledge on gravity and how it works. They have each left a unique mark on the scientific community. The Greek philosopher Aristotle was the first of his kind, coming up with the first theory about gravity even existing around the 4th century BC. Aristotle’s belief was that there is no effect or motion in the universe without a cause for it. He believed that heavy bodies moved downward toward the center of our universe, while light bodies moved toward the Moon. A heavy body would be something like the element of earth, not the Earth. While a light body would be something like the element of fire. Aristotle also believed that objects of different weights fall at different speeds. This gave the belief that heavier objects should fall at faster speeds than lighter objects. The next scientist to have a voice on the theory of gravity is the Italian scientist Galileo Galilei. Galileo showed that Aristotle’s assumption that the speed of falling bodies is determined by their weight is outright wrong. He said...

...ne hot sunny day at Six Flags over Georgia a little boy thought to himself, “how does the roller coaster go up so high?” A worker spots him and go over and asks “hey young man what are you thinking about?” The little boy smiles and asks “how does a roller coaster work?” I grin and say “Well young man you're in luck because today I'm doing a tour,and i will be talking about the physics of roller coasters. Do you want to join?” He jumps and gets excited, “ YES YES!” With that, i gather more kids and begin tour. This roller coaster is called the Loopdy Loop and it is one of the biggest roller coasters in the park. A roller coaster is a machine that uses gravity and inertia to send a train of cars along winding train. This combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track....

...steady speed is called inertia. The second law explains that an object’s acceleration depends on its mass and on the net force acting on it. Basically, it explains how a force acts on an object. An object accelerates in the direction the force is moving it. The third law states that if an object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object. In other words, if an object is pushed or pulled, it will push or pull equally in the opposite direction. When most people think of Isaac Newton, they think of him sitting under an apple tree, observing an apple fall to the ground. When he saw the apple fall, Newton began to think about gravity. Newton understood that gravity was the force of attraction between two objects. He also understood...

Standard deviation of compound’s values were used to create error bars. Figure 2 shows the value of specific gravity of compound B for the individuals who were tested by the Environmental Protection Agency after reports came that people got sick due to compounds in new cleaning agent entered nearby water supply. Standard deviation of compound’s values were used to create error bars. Figure 3 shows the urine production rate of compound A (mL/min) in individuals who were tested by the Environmental Protection Agency after reports came that people got sick due to compounds in new cleaning agent entered nearby water supply. Standard deviation of compound’s values were used to create error bars. Figure 4 shows the value for urine production rate (mL/min) of compound B in individuals who were tested by the Environmental Protection Agency after reports came that people got sick due to compounds in new cleaning agent entered nearby water supply. Standard deviation of compound’s values were used to create error bars. Analysis: In figure one, the bar graph shows the level of specific gravity in compound A during control (which was taken before the contamination of water) 30 minutes later, and then again 60 minutes. Here we see that compound remain on very same level, but specific gravity did decrease little during three different times...

...while before in the year 1667, he had been elected as a Fellow of the Trinity College. Most of his years, he spent lecturing at the Cambridge University until the year 1696 when he moved to London (Krull & Kulikov, 2006). According to Krull and Kulikov (2006), during his college life, Newton used to write the ideas he conceived in a journal. Some of the ideas included gravity, forces and the lights diffraction. His ideas were excellent, a thing that made him to be knighted in the year 1705 by Queen Anne. His ideas had an impact that revolutionized the world and made and laid the foundation that has been adapted by modern science. He was a physicist, philosopher and mathematician. He is remembered as one of the greatest intellects of science of all time During that time, he as a firm opponent of King James 11 due to the kings interest and plans to transform universities into institutions of the Catholic religion. He later on died in the year 1727. Force of Gravity Parker (2003) suggests that the story that is well known explains that Newton discovered the existence of the force of gravity after he had seen an apple fall some time during the mid 1960s. The falling of the apple made him conceive the thoughts that, the same force that made the...
