Chemical explosions are one of the coolest things on the planet. A chemical explosion is the sudden, loud, and violent release of energy that happens when something breaks apart in a way that sends flying around(Explosion). The chemical explosions starts from the chemical reaction(Getting a Bang Out of Breath Spray). .
The great challenges and Engineering solutions to the problems of the 21st century Title: Nuclear fusion Author: Ashley Pinto (B00078756) Date: 28-09-2012 Introduction: In this essay I hope to talk to you about nuclear fusion. I will do this by outlining a few important aspects to take into consideration when talking about nuclear fusion.
Analysis: Although only a simple water bottle rocket, it still applies to basic rocket theory. The simplest equation which applies is Tsiolkovsky's equation which describes a device that can apply acceleration to itself (a thrust) by expelling part of its mass with high speed and thereby move due to the conservation of momentum. In short the momentum which the rocket gains is that momentum which the water loses as it is expelled. The equation is: ∆v=V_e ln(m_o/m_f ) Where: ∆v = change in velocity (m/s) V_e= velocity of exhaust leaving nozzle (m/s)
From our first rocket, we discovered that we had to be more sparing regarding the outside design elements on the projectile. The feathers we had constructed from colored paper and then attached to the body and wings of the rocket had weighed it down, increased air drag, and inhibited the possibility of a successful launch. From that experience, we knew not to put so much extra elements onto the body of the rocket in order to promote a smooth flight. Overall, the first rocket that was crafted was far too heavy, and when water was added to it, the projectile’s mass was overbearing thus reducing the height and travel time of the launch. The first bottle rocket we had made this year taught us many lessons regarding beneficial construction techniques, and provided guidance for the manufacturing of our second
Ray Bradbury’s 1950 dystopian novel, The Rocket is a short science fiction classic based on a man who fantasizes of travelling to space. This futuristic tale communicates, how anyone is authorized to travel to space without any prior experience and preparation on how to operate and navigate a rocket. The story of the The Rocket, is based during a more advanced time in the future as anyone at that time is able to fly to space as long as they have money to support their trip, the protagonist is a father, named Fiorello who wants to bring his family to space, but to do that he must save a lot of money as the trips are far too expensive, nobody believes that he will be able to accomplish this task and even when people are that it’s impossible
The passage is mainly talking about Professor Wolfs and what he teaches his students and what he tells him what to do when in a scienctific related problem. Professor Wolfs talks about a method, "the process by which scientists, collectively and over time, endeavor to construct an accurate representation of the world. " This is what he tells his students. For the limitation of a scienctific method, you must look threw some research, form a hypothesis to use in the future for studys and tests. Use the hypothesis you made and expirement with it to see if the results are true or false.
The USA were determined, this could really change their position on the international scene. NASA scientists developed the Apollo 11 (“Cadbury”), a rocket capable of sending three astronauts to the moon and come safely back on Earth. The astronauts were Neil Armstrong, Buzz Aldrin and Michael Collins (University Nebraska). The Launch was on the 16th of July 1969, more than 500 millions people were
“How to Poison the Earth” by Linnea Saukko was written as an assignment for a freshman composition class. This essay details a process that humans could take to ensure the definitive destruction of earth. The writer explains that this process might be difficult, due to the fact that the earth has ways to continuously cleanse itself. The first process suggests that large amounts of lethal substances, such as uranium-238 and plutonium, should be produced and then injected into the earth. We would start by building more nuclear plants to help generate more plutonium.
Though Einstein’s theory of relativity has been responsible for serious scientific and technological advancement, Einstein initially proposed his theories from his own thought experiments, considering previous theories and reaching contradictions or abnormalities. An example of this is, “what would happen here on Earth, if the sun suddenly disappeared?”. If Earth broke out of it’s gravitational orbit, and took a different trajectory, before the sun’s rays could reach the observers on Earth (8 minutes), then essentially gravity travels faster than the speed of light. A contradiction.
As the step rocket burned out and fell off in the sky, the firework would continue going much farther than it would have normally gone. This technology is still used in rockets today, and is in part responsible for our vast improvement in rocket technology. According to nasa.gov, in the 17th century, Isaac newton created three laws of motion. These collectively explained how rockets could move in space, and how they could one day be used for space
Experiment 13.1 Purpose: To determine the ∆H of a chemical reaction. Materials: 2 Styrofoam cups, Thermometer, Vinegar, Mass Scale, Measuring tablespoon and ½ teaspoon, Lye, and Safety goggles.
3,2,1 Blast off! Apollo 13 was launched into space on April 11, 1970. Little did the three crew members know that they were aboard what one day would be considered NASA’s greatest failure. There are many reasons for people to better understand the problems in Apollo 13. First, the main problem was the oxygen tank that was blown up during the blast off.
John F. Kennedy, a former president of the United States, delivered his “Cuban Missile Crisis” speech on October 22, 1962, to the United States citizens and captives in Cuba. Those people were terrified of a nuclear missile attack during the Cold War time period. Due to the primary use of logos in Kennedy’s “Cuban Missile Crisis” speech, he informs his audience about the type of missiles in Cuba and the steps to be taken to respond to the Soviet Union’s placement of missiles in Cuba. This would hopefully alleviate some of the fear of the citizens of the United States. He shows pathos by continuing to ease the citizens’ fear of a missile attack by showing compassion towards the people.
The purpose of this lab is to use the Diels-Alder reaction to combine anthracene and maleic anhydride. Named after its two founders the Diels-Alder reaction is the addition of a conjugated diene (electron rich compound) with a dienophile (electron poor compound). (1) These compounds will be combined using [4+2] cycloaddition, where the numbers 4 and 2 come from the number of π electrons that are used in each compound to synthesize the product. (2) This experiment comes at the cost of losing two π bonds to form two new sigma (σ) bonds in the cyclic compound. (2)
