In chapter five, Pink discusses the trait of “buoyancy,” or what he defines as the ability to stay afloat when waves of rejection and adversity strike. According to Pink, buoyancy is composed of three different components: interrogative self-talk, positivity ratios, and explanatory self-talk. In the first component, Pink suggests that instead of only using positive self-talk whenever we are planning to move someone, we use interrogative self-talk. This is because asking ourselves questions, such as “Can I do this?” will elicit reasons for doing something, create room for improvement, and produce better results.
In conclusion, air pressure has a direct influence on the distance that the ball will travel when thrown. The hypothesis stated that if pressure is added to the football, then the distance the ball projects will increase when distance is a function of pressure. Based on the data that was collected from the experiment, the hypothesis was supported. When the football had more air inside, it went the farthest distance compared to the other two pressures that data was collected from.
The cause of the incident was determined as a malfunction in the O-rings, which had been designed to separate the sections of the rocket booster and had failed to do so due to cold weather. Engineers working on the space shuttle on the day of liftoff warned their superiors of the vulnerability of the O-rings at low temperature, these warnings were ignored. The American shuttle orbiter Challenger exploded 73 seconds after take off. The families of
In both books Bound by Donna Jo Napoli and A Long Walk to Water by Linda Sue Park the main characters Salva and Xing Xing have doubts about father figures in their lives. In Salva’s circumstance, his Uncle, halfway through their journey, tells Salva that he will not stay with him. Salva realizes he will no longer have any biological family with him anymore. He feels betrayed and is lonely for a while after his Uncle’s decision. Shortly thereafter, Uncle is brutally shot and murdered leaving him is alone again.
Repeated trials may prove to wear this down. The experimental error of the trebuchet can be calculated using this formula: Experimental Error % = (theoretical value-measured value)/(theoretical value)100
In 1933, Poland had the largest Jewish population in Europe, numbering over three million. By the end of the holocaust in 1945, the Jewish population of Poland was reduced to about 45,000. Oskar Schindler saved about 1,200 Jews. Most of the Jewish survivors of the holocaust had a positive attitude during their ordeal, in particular Leon/Leib Leyson (one of the 1,200 Jews Oskar Schindler saved during the holocaust) was very selfless and had a very positive outlook towards life in general even during his hardships of the holocaust. He showed this when he saved an old woman 's life by taking her to the infirmary and stayed past his curfew.
Lab Group: Thomas Echelberger, Austin Brown, Erik Holden, and Josh Peeples Introduction: For this lab we had to construct a projectiles launcher that would shoot ping pong balls at different distances. At the beginning of the project we though of doing a generic catapult made of popsicle sticks. But we wanted to go above and beyond. So we decided to make a launcher that would use air pressure to power the ping pong ball.
The hypothesis was made from the evidence that the flame from the flight and the smoke following liftoff came from the right side. The joint that failed was called the Aft Field joint. It connects to the aft segment with a nozzle. The joint failed on the Right Solid Rocket Booster. Another possible cause is the “putty”.
In the realm of human anatomy and physiology, it is a standard assumption to claim that there is a distinct correlation between an individual’s height and wingspan. Wingspan can be defined as the extent across a person’s arms from fingertip to fingertip, while height in the measurement from someone’s feet to the top of their head. The typical human body has a height that matches a person’s wingspan. For instance, if you are five foot tall, you are assumed to have a wingspan of five feet. The correlation between height and wingspan is often expressed in a ratio of wingspan over height, which normally is recorded around 1.0 given the information regarded above.
In a projectile, the only force is gravity, thus resulting in a downward acceleration. Gravity does not act in the horizontal direction, so the ping pong ball will theoretically travel at the constant horizontal velocity according to the law of inertia. Communally characters of ping pong balls and the nature of projectile motion will have important effects on the launcher that must be considered to ensure that the launcher fulfils the expectations
After years of engineering and constructing one of the most anticipated rockets, SpaceX poises Falcon Heavy for launch on February 6. The gigantic space vehicle is the most powerful, operational rocket--even more than NASA’s long-reigning Saturn V, which last took flight in 1973. The Falcon’s massive size, housing 27 engines, will carry huge cargo loads and could host an opportunity for human missions to the moon and Mars. As you watch the launch, here’s what you should know about this history-making spacecraft.
Background As engineers it is important to understand the difference between simulated results and experimental results. Although simulated results can be helpful when designing a project, they may not necessarily align with what is observed in the real world. The difference between simulated results and experimental results is best summed up in the phrase all models are wrong but some are useful. This lab serves as a means to display the difference between simulated and actual results. 1.2 Purpose Compare the theoretical performance of a model rocket to the actual performance of a model rocket.
The ponderous, mythical opening of visionary auteur Guillermo del Toro’s Oscar-winning film The Shape of Water gently guides us into its unique blend of horror and romance, surrounded by the same magic del Toro effortlessly captured in its spiritual predecessor, Pan’s Labyrinth from 2006. In the age of superhero blockbusters, endless sequels and reboots, del Toro’s sensual adult fantasy manages to make its voice heard amidst the cacophony of studio demands and creative restriction. Set during the height of the Cold War in Baltimore 1962, the film follows the journey of mute custodian Elisa Esposito (played with aplomb by Sally Hawkins), who works at a high-security government research facility, and a amphibious humanoid creature captured from South America. Elisa proves that vulnerability is not a sign of weakness, that she doesn 't need to hide her identity under cynical facades; there is a nuanced strength at
What is the effect of surface area to volume ratio on the rate of diffusion of the colour from the agar jelly cube? INTRODUCTION: Diffusion is the movement of spreading particles from high concentration to low concentration in an environment such as a cell. This major procedure is used in cells to source them with nutrients, water, oxygen, and to transport unwanted wastes such as carbon dioxide out of the cell or to different cellular organelles.
I taped the back of two plates together which is a wheel of the car, and used sticks to connect all four wheels, then I putted the balloon to the car and start our first trying. Surprisingly, the car didn’t move at all! Why, it is not as well as I thought. I failed in the first trying. I told myself, “One fail will not prove anything, I can do it”.
