PREPARATION My biology hero, Joseph Priestley, really impacted the world. He impacted the world by discovering oxygen, inventing sparkling water, and helping his colleagues contribute to electricity. Many people do not appreciate and recognize him as much as Albert Einstein, Thomas Edison, Benjamin Franklin, etc. Joseph Priestley showed his intelligence as an child by studying math, logic, metaphysics, and philosophy. He also fluently spoke six languages.
The third instance is after the chain of dominoes collapse and send the marble rolling down the inclined plane. The speed of the changes the distance it will go, therefore it had to be the exact acceleration in order for it to land into the cup. Negative Acceleration is shown when again in the pulley system whereby the string and force of the cup the second cup is pulled up as the same direction of the nvelocity. It then slows down showing two indications of a negative
When the hot water was added it made it rise to the top of the container and spread. That showed us that the bottom layers would be hotter and the top layers would be colder. The asthenosphere is making convection currents. Since the convection currents are always moving it causes the asthenosphere to move and bend because it is ductile. When the asthenosphere moves which is under the tectonic plates it will cause an earthquake or more specifically the Alaskan Way
“Does the Mass of a Ball affect its bounce.” Yes mass does affect how high a ball will bounce. It does because the more mass a ball has the more kinetic energy it gets due to gravity. When the ball hits the ground its kinetic energy is turned into elastic energy and the more kinetic energy there is the when the ball is bounced the more kinetic energy it will have going back up. That is how mass makes a ball bounce
Because of the rainstorm, the cords became wet after four minutes. As soon as the cords were connected to the ground and wet, the frame was grounded. This led to the sudden potential difference between the frame and the skin. As a result, the electrical discharge happened between the skin and the frame. The spark tried to find the quickest way to ground, so it jumped from the skin onto the frame which was made of metal.
Abstract: Mathematics is a great subject that has developed greatly throughout the years. It has been present for a long time and throughout different societies. The American Indians are a group of people with an incredible culture full of amazing facts. Evidence of their work proofs their knowledge and understanding of different mathematical concepts that only makes us admire their culture even more. Such evidence allows us to explore how the American Indians counted and how they displayed mathematical understanding in their earthwork and art.
“As the ball moves through the air, the air parts around the ball. Behind the ball, the airstreams that separated come back together” (Bend It Like Magnus). To kick the soccer ball farther than normal, the ball needs to be pumped up harder than most other soccer balls (Live-strong). Magnus effect is the force exerted on a fast spinning cylinder or sphere moving through air or another fluid in a direction at an angle to the axis of spin (Magnus Effect/Physics). “The ball is like a rock in a fast flowing river — the water splits around the rock, then swirls to fill in behind the rock, causing turbulence” (Bend It Like Magnus).
Rube Goldberg, during his lifetime, was a well known cartoonist who utilized his engineering knowledge within his created drawings. Goldberg’s legacy introduces students to his methods of incorporating extravagant machines that contribute towards completing a very simple task. For instance, Rube Goldberg captured the attention of numerous citizens following a cartoon which used a lengthy chain reaction to merely wipe the characters mouth with a napkin. Thus, complex machines which accomplish simple tasks are called Rube Goldberg machines. Due to Mr. Goldberg’s cartoon and engineering background, Rube Goldberg machines allowed him to create devices that captured the attention of viewers and exercise his physics knowledge.
Earthquakes are caused when rock underground suddenly breaks along a fault. This sudden release of energy causes the seismic waves that make the ground shake. When two plates are rubbing against each other, they stick a little. Most earthquakes occur along the edge of the oceanic and continental plates. Due to stress they shift and cause the earthquake.
In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
Genius When using gas in the egg drop challenge, it spreads the amount of energy transferred from the ground to the egg. Making the energy from the ground to the egg less, because if you look closely at a balloon filled with air. When it hits the ground, the gas in the balloon spreads out inside the balloon, and then contracts back. The solid object (the egg) on top of the balloon will sink into the balloon, because it’s a solid and heavier than the gas in the balloon. Let’s say you have an egg that weighs about one pound, you have to build a sculpture that slows down something moving at 9.8 meters per second.
To me, engineering is a discipline full of numerous rewarding possibilities such as a high amount of salary right after earning a bachelor’s degree from a university. Furthermore, engineers are able to solve worldwide problems by utilizing the application of mathematics and science combined. In this process, engineers are tasked to simply analyze a problem using their intellectual and critical thinking skills and then come up with a solution to the primary problem. Therefore, the dream and quest of becoming a software engineer after college graduation has actually grown into a larger temptation for me. The software engineering industry is one of the brilliant environments of engineering where I can develop and test programs for the sake of benefiting mankind.
