Alka-Seltzer has been on the market since 1931 and has helped to relieve indigestion and upset stomach. The tablets began to fizz and bubble when dropped into water. “The fizziness happens when baking soda (sodium bicarbonate) and citric acid react chemically in water. They yield sodium citrate, water and carbon dioxide gas, which causes bubbles.” Based on this information, we will measure the reaction time of AlKa- Seltzer dissolved in 200 ml of water at 3 different tempertures in the first portion of this experiment. In the second portion of this experiment we will keep the temperature constant and divide the ½ tablet of Alka- Seltzer into 2 pieces ,3 pieces and an unbroken ½ tablet. It is my belief that Alka-Seltzer
The items that were massed were the evaporating dish, watch glass, and NaCO3. The materials were massed once before and once after being heated in the drying oven. The mass of the evaporating Dish before was 46.57 g; while after being heating was 60.15 g. The mass of the watch glass before was 57.97 g and after was 48.75g. There were two masses taken for the substance NaHCO3- one with the evaporating dish and one without, subtracted out after the lab was concluded. The mass of the substance with the dish was 48.79 g before and 62.33 g after; meanwhile, the mass of the substance without the dish was 2.22 g before and 2.18 g after. The mass of the NaHCO3 had changed after the reaction occurred along with after it was placed on the hot plate and being in the drying oven. When the reactants were in the evaporating dish with the hotplate on, the acetic acid and sodium had been chemically bonded in a combustion compound. The mass went from two different reactants to one product and two evaporated
In a passage from The Great Influenza, author John M. Barry writes about what it is like to be a scientist. He describes scientists as pioneers and uses that to get across his idea. The author states that being a scientist is brave and uses metaphor, the motif of an explorer, and logos to prove his point.
In 1679, Newton 's mother died which caused him to become extremely isolated for six months; he used this time to study gravity. Although Newton is best known for his work on gravity he also had many physical inventions. He is also known for the invention of calculus as well as another mathematician who they say invented it at the same time. Later on, he then published a book titled Philosophiae Naturalis Principia Mathematica which is considered to be one of the most influential books in the history of science today. Newton was elected president of Royal Society after the death of Robert Hookes in 170 3. He worked for the British government as the master of the Royal Mint. He continued to elected as president of the Royal Society until his death. Newton said, “My powers are ordinary. Only my application brings me success.” Although he was very successful he knew that his hard work was the reason he got to where we he was. Even though Newton had to face many struggles in his early life between growing up without a father, his mother leaving to live with her new husband, and his mother then dying he was still able to accomplish and bring many new things to the world. Many of Newton 's creative ideas and inventions he brought to the world are still used today. For example, in 1666, Newton came up with the Theories of Gravity. A few years after developing The Universal Law of Gravitation, he created the three Laws of Motion. The first Law of Motion states that every object
Imagine a ball sailing into the back of the net and the crowd going wild. Do you ever wonder why it got there with such power? Of course you do! Think of Newton’s First Law of Motion. It states that an object at rest will stay at rest, and an object at motion will stay in motion unless acted upon by an outside, unbalanced force. Say the goal was scored from a
Newton 's Laws of Motion: three laws that state mechanics portraying the movement of a body. The main law is the law of latency: a body stays very still unless followed up on by an outer power. The second law expresses that a body in movement stays in movement unless followed up on by an outside power. Newton 's third and last law is about how for each activity, there is an equivalent and inverse response.
Another force that can effect the flight of a paper airplane is the force of lift. Lift is when the wing is getting pushed upwards harder than it is getting pushed downwards. If this is happening, then it means gravity is not as strong on the plane as thrust and lift are. Lift is the starting point and the middle of the flight. If the plane is moving upwards, lift is taking place. When a paper airplane is going down, lift is not taking place.When the air is going under the wings of the plane this is also lift. Without the wings there is no lift which means the flight would not last long. The factors weight, size, and velocity are depended on by the magnitude of the lift. So it is saying that other smaller forces depend on the lift which
Gravitational waves predicted by Albert’s Einstein’s general theory of relativity have been detected directly at last. Einstein was right.
Isaac Newton’s legacy was discovered gravity and made the laws of motion. according to pbs.org “he discovered gravity when he saw an apple fall from tree”. this changed the world later on e e because after Isaac Newton figured out gravity people started to understand that gravity is the thing that keeps us on earth. “Isaac Newton also made the 3 laws of motion by testing objects to see if it was true if an object is in rest it will stay in rest until an outside force acts upon it”. after Isaac Newton created the 3 laws of motion it changed the world later on because people also started to understand that things in life are not going to move by themselves you have to act upon it. “Lastly Isaac Newton discovered that the planets orbit around other planets and the sun and the discovered that the sun keeps is warm”. after
Two years later he was appointed as a mathematical professor. Then in 1668 Isaac’s reflecting telescope that brought him to attention. During the mid of the 1660’s he constructed a variety of experiments on light. Then in 1687 he published his greatest work the “Mathematical Principles of Natural Philosophy”. This was the first discovery he published in 1687. It was the foundations for mechanics where he formulated the three laws of Motion. The first law states, “An object at rest will remain at rest unless acted on by an unbalanced force. An object in motion continues in motion with the same speed and in the same direction unless acted upon by an unbalanced force” (Newton). The second law says, “Acceleration is produced when a force acts on a mass, the greater the mass of the object, the greater the force required to accelerate it” and the third law tells, “For every action, there is an equal but opposite
He influenced inventions like the Newton’s cradle, which uses his concept of gravity to keep hanging weights in motion. “Newton’s universe united Heaven and Earth with a single set of laws.” (Hatch, R) Newton’s discoveries became the foundation for many technological advances, and the base for most of today’s science. His findings influenced many engineers’ tools. Newton found a way to relate gravity with mathematics. This has assisted engineers to make accurate measurements and diagrams through his Calculus, Oculus, and Gravitational theory.
A ‘law of nature’ is a general rule that is discovered through reason. This law supports the claim for human self-preservation and condemns destruction of humanity. It does not need to be written down because it is natural and made known to all by mental faculty, reason or philosophy. In Leviathan, Hobbes presents, what he thinks, are the three most important laws of nature. He sees them as important because he believes that, these laws will create a state of peace, in a state where humans are constantly at war against each other. It is noted, that Hobbes called these laws, “theorems”, rather than actual laws, as he understood them to be moral recommendations which people should follow in order to live in a peaceful society.
Newton has discovered and proven many great concepts throughout his lifetime that he needs more credit for. His research about the three laws of motion was “still recited by physics students”(livescience.com). “During his lifetime Newton developed the theory of gravity, the laws of motion (which became the basis for physics), a new type of mathematics called calculus, and made breakthroughs in the area of optics such as the reflecting telescope.”(ducksters.com). Newton was overall a very important scientist, philosopher, astronomer, and mathematician that explained gravity which is a fundamental concept of
Response: I, Democritus, state that there is motion in the world, due to the fact this is how one can account for the perception of different qualities. There are two realities we must account for: atoms and the void. The properties of the atoms are they are basic, indivisible units that do not come to be or pass away, do not change and are unified. Atoms are infinite in number, come in different shapes and postures, have existed for ever and are all uniform. The atoms are too small to be detected by the senses, but they make up everything in the world. All these basic requirements of atoms fulfill the requirements Parmenides set for being. The main difference being, I, Democritus, account for a void and do believe atoms are always moving.
The theorem can be explained by the means of imagining a particle in a cylindrical pipe. If the pressure on both sides of the particle in the pipe is equal, the particle will be stationary and in equilibrium. By implementing the second law of motion the particle will accelerate or decelerate if there exists a pressure difference over the particle. The particle’s velocity will increase when it is approaching a low-pressure region and decrease its velocity at a high-pressure region. This principle can also be seen in terms of pressure. If a fluid is slowed down in the pipe the pressure will rise and vice versa.
