This was then tested against adding more weight in the second table, which increased the acceleration due to gravity, which made the second table faster than the third. While the third table went the slowest, because of the added weight on the cart which pulls back against the weight end more than tables on and two. This whole process in finding a_calculated would be the same as finding F=ma. Which makes this lab fully about testing Newton’s 2nd law and then checking out findings with percent
We had some jenga pieces and duct tape holding the marble slide up. Also, we hammered the slide to the wood with the nail that acted as a pulley. The slide would be classified as a inclined plane. We were required to use the duct tape, marble slide, and
12. The TLC data obtained is provided in a table below. The TLC data was conducted solely in a 9:1 hexane/ethyl acetate solvent solution as opposed to the 1:1 and pure hexane solution as well. This was due to the lack of time, but as explained in number 7, a very polar solvent (1:1 solution) or non-polar solvent (pure hexane) is not ideal when obtaining
The only difference from normal phase is that the column now is modified in order to attach long hydrocarbon to it surface. When a polar solvent is used strong attractions between the polar solvent and polar molecules in mixture being passed through the silica. Polar molecules will spent most of the time moving with the solvent because there will not be as much as attraction between the hydrocarbon chains attached to silica and the polar molecules in the solution. About the non polar mixtures, because of the Van der Waals forces will tend to form attractions with hydrocarbon
I also did horrible in the tests, but I was able to push through that and I managed to pass the class with a B. My weakness this year was probably not having enough sleep. I get cranky when I don’t get enough sleep, and I realized I can’t focus when I’m in class. My strength this year was probably becoming more organized and setting a specific schedule for myself everyday. Since I have to work, I need to make specific time for my homework.
This debris and piece of Earth molded together to form the Moon. The Moon then stayed and started orbiting the Earth. This theory explains why the Earth has a smaller core that is made of the same material as the Earths core. The impact from the collision could have resulted in the "Earth 's fast initial spin" (Newman). The energy from this collision is an explanation for the extra heating of the Moon.
Physics Lab Report Name – Shaurya A Singhal I.D – 13229 Grade – 12 Investigating the effect of the angle of incidence on the diameter of a Crater formed by a falling object Introduction When a bob is dropped into sand, a circular crater is formed due to the impact of the ball. The size of the crater varies with numerous factors, Mass of falling object Angle of incidence Velocity of object Rigidity and Tensile Strength of surface on which object falls Background Theory When a high-speed object strikes a surface, it produces an enormous amount of energy. This is called kinetic energy because it is caused by motion. The amount of energy produced in this way depends on the mass of the impacting object and the velocity with which it strikes the surface: KE = ½mv2, where m is the mass of the object and v is its impact velocity. Asteroids hitting Earth have impact velocities from about 11 to 25 kilometres per
Reading is a fun experience but a really hard one to focus on. The first book was an alright read. It was a great book that had a lot of twists and had an interesting, thick plot. The next book would have been a great read, but I shot too high and came back with very little results. When I broke my arm I missed 5 days of school or approximately an hour of reading and I had too much homework to catch up.
Statistics from Energy Fresh web site, par 3. Research question 3: What are the dangers of space junk? Space junk fragments represent the objects travelling at extremely fast speed, about 8 kilometers per second. If even a very small piece of debris hits a satellite, spacecraft or astronaut at that speed, it could be very serious damage and accident: it can kill an organism or split and explore big satellites and other space machines. Moreover, without taking into account the collision and accident, space junk carry the danger of pieces falling back to Earth.
This is because the paths of asteroids can be affected by many different gravitational pulls throughout the solar system, including the gravity of the sun, of planets, of moons, and even other asteroids.The butterfly effect comes from the chaos theory to describe how a small change or mistake can create a different outcome.”(wiseGeek). The butterfly effect not only dealt with things on the Earth but also with things in space. “Examples of these complex systems that Chaos Theory helped fathom are earth 's weather system, the behavior of water boiling on a stove, migratory patterns of birds, or the spread of vegetation across a continent. Chaos is everywhere, from nature 's most intimate considerations to art of any kind. Chaos-based graphics show up all the time, wherever flocks of little space ships sweep across the movie screen in highly complex ways, or awesome landscapes adorn the theater of some dramatic Oscar scene.”(Abarim Publications).
This science fair project is a mechanical catapult that will be electrically modified to pull back on its own. The goal of this project is to see how far an eraser cap will launch with two different forces that pull the catapult arm forward very fast. From this, we will see if either a bungee cord, or fifty to one-hundred rubber bands has more elasticity. One real-world situation we would want more elasticity for is holding things together, or hooking things together. In this project, recording of the control and data trials will be included into a bar graph, as an average.
The drawings weren’t as beautiful as I remembered them being, but what can you expect from a fifth grader? That would be my worst research experience because it always makes me second guess my reports before I submit them, and then fret until I get the
It causes an aneurysm in your heart, the aorta specifically, and you’re very likely to die if it actually happens. It can be caused by activities that raise your blood pressure: doing too much physical activity or even having energy drinks. A lot of the symptoms of Marfan’s syndrome were ones I had because it’s related to EDS. There were only a couple of symptoms that I didn’t have, which was pretty scary to know when it came to waiting to hear if I had it or not. Luckily I don’t have it, otherwise my life would be so much
Having the research be longitudinal is also really good when it comes to presenting the effectiveness of Head Start REDI program. I wonder why they chose to end the study at third grade instead of continuing it up until they leave elementary school. The researchers provided a lot of information about the Head Start REDI program and how it was more a benefit for kids who live in poverty. A weakness that I found is that it was hard for me to read the data. Typically, a research paper should be at a 5th grade reading level but, I often found myself lost in the paragraphs and unable to understand how the data was measured.
Did you know that it takes about 1/4 of the bottle filled with oil just to make the bottle? That means that it takes more than 17 million barrels of oil to produce these plastic bottles. In my opinion, I think that tap water is more safe for us to drink and also, more safe for the environment. Human Safety is one of the major problems with bottled water and tap water. Bottled water does not contain any toxins or chemicals that are bad for humans.
