Nose Cone Hypothesis

There are many approaches to this problem. The most common method is creating a separate air chamber using an empty soda bottle. A weight drops on this bottle to exert air pressure. This air pressure is then used to launch a projectile, adjusting the height of the weight as needed. Although easy, this method is too imprecise and will yield inaccurate results. To begin, it is needed to learn about how air pressure is created and the best way to achieve it. After

My design used a pressure of 600000, coefficient drag of 0.05, a temperature of 4 degrees celsius, 2 liter size bottle, it was filled 70% with water, a nozzle diameter of 0.02 meters, a ballast weight of 0.03, and had the cone of the bottle rocket on. I picked the variable of the cone on/off, percentage filled with water, and size of bottle as my three most critical variables. I picked them because during the runs where I was testing these variables, the altitude and velocity had significant changes every time. There were some variables such as ballast weight and temperature at launch that didn’t have as drastic changes with each run so they were not as important. One thing that noticed is that the velocity was consistently higher than the altitude so when testing it, I was more focused on raising the altitude. When I was focused on the altitude, I never noticed a significant drop in velocity so I don’t think there were any trade offs with the results from this

The hypothesis was “If the height of the ramp increases then the speed of the toy car will increase because the the time taken to get all the way down will increase, so speed will increase.” The data supports the hypothesis. As the height of the ramp increased so did the speed of the car. This shows a positive trend. When the ramp was 10 cm high, after rolling for 30 cm, its speed was 23 cm/s. When the ramp was 15 cm high, after rolling for 30 cm the speed was 33.3 cm/s. At 10 cm, when the car rolled for 60 cm, its speed was 26.9 cm/s.

For example if the fulcrum was to be to close too the lacch it would most likely hit the ceiling. Also, if the fulcrum was too be too far from the launch it would also hit the ceiling. The best location for distance when launching the snowball was 3 fifths of the beam away from the launch. This location made it too where the snowball gets distance and some height so that the snowball doesn't hit the ceiling and comes back down and goes really far but luck wasn't on our side for the competition. 2.Explain how the speed of the effort and the amount of effort applied changed the flight of the snowball.

Sports equipment has been innovated countless times and helps keep sports players safe and also helps them perform better. One evolution that occurred with football equipment is innovation of a new, safer, helmet. According to Bleacher Report, the first helmets were made out of “leather straps or mole skin (Daughters 1)”. These helmets did little to protect its users, as it didn’t even cover the entire head. Then, in 1940, the plastic helmet was introduced to the sport of football.

One part of the experiment was to test four different object free falling from the same height and recording their time with a stopwatch and again with a photogate. The second part of the experiment was to the take one of the four object that had a acceleration nar 9.8 meter/second sq. and testing it 15 more time with different height. Material Needed Stopwatch, meter stick, photogate, pen, ball, water bottle, pill bottle, and ring stand.

First get your 4 pictures. We found these at www.exploratorium.edu. Then you will need a pink and green see through clipboard that is 8.5 by 11 inches. Before you start the experiment you need to have a clean room. Next find four twelve year olds, two boys, two girls. Then you need to collect the rest of the materials.

Launch trajectory Initial speed (for varying shape) To ensure that the data collected was accurate and has the least variability as possible, measurements of variables and controlled factors for the investigation must be taken into account. The independent variable; the mass was measured by using the same digital scale in every trial and manipulation; the paper was placed onto the scale unfold and brand new after every trial without using the same paper airplane for a new trial. The experiment was measured by using the same exact camera in every trial to ensure the same variability and has made sure that the distance between the camera and the paper airplane was kept constant because it can affect the readings of the camera. Wind can affect the flight path of the paper airplane; this was measured but was accounted as an error that cannot be fully controlled due to the outdoor environment the experiment was carried in. A suggestion to this dilemma is to conduct the experiment in a closed system, where wind blows are not present.

* To reduce threats to internal validity I cannot be biased toward one design more than another. I did not choose a paper airplane that I had seen before. I chose three paper airplane models at random so I wouldn’t have a chance to think one was better than the other. I also do not want to change anything

What we changed: To decrease the time to fall, we maximized the launch speed while simultaneously reducing the height to a minimum and launching from an angle of 0 degrees. The time a projectile spends in the air is directly related to the angle measurement and height. The greater either of the two variables, the more hang time a projectile would experience. Therefore, to reduce time, our group minimized both variables, effectively rendering time from increasing. Furthermore, our group increased the launch speed because a faster velocity meant that it would reach the ground faster in less time.

On one side of the straw there was two wings paired together and about 45 degrees apart; on the complete opposite side, there was the other set of two wings positioned the same way. Additionally, this design team also plugged the front of the straw by forming the modeling clay to a point and they moved around and adding clay to position the center of mass just behind the middle of the rocket. Both of the rockets were designed to be fairly aerodynamic with relatively small wings to reduce the effects of air resistance, by as much as physically possible without compromising the stability and consistency of the flight path. After a few test launches we collectively decided that team’s two rocket a better and more consistent flight, so we declined team’s one rocket design and continued the rest of the testing and data collection with team’s two rocket. After moving out to the stairwell for some vertical launches we found out that Roman’s and Dylan’s rocket had too much mass for the rocket launching apparatus to propel the rocket to a height that would clear the railing, even when using the maximum plunger drop height. With this dilemma, our team had to enter back in the design phase in order to modify rocket in such a way the would reduce the mass without compromising the favored flight path

The nose, as an organ initiating reflexes affecting itself and the rest of the body, and as a target organ of control, is highly complex. Its innervation includes parasympathetic, sympathetic, sensory/afferent, and somatic motor nerves, which combine in a variety of morphologic pathways. The vasculature of the nose contains capacitance vessels such as sinusoids and distensible venules, as well as arteriovenous anastomoses, arterioles, capillaries, and venules. The secretory tissue of the nose includes epithelial cells, submucosal glands, and relatively large anterior or lateral serous glands; in addition, some species have specialized secretory glands. The nose is the source of many powerful reflexes, including the diving response, sneeze and sniff reflexes, and reflexes affecting autonomic nervous function to the cardiovascular system, airways in the lungs, the larynx, and other organs.

Lucy’s nose is very cool because she can smell ten times better than us so what my brother and I do with her to keep Lucy’s nose, fresh as my dad says is we run around the yard and hide one at a time. My dad picked a spot in the yard like I have hidden under a wheelbarrow, up a tree, under a trailer, in between trees and every time I heard she finds me. My dad told me the reason that she rubs her ears on the ground is so she can the scent of what she's looking for in this case us she use the aroma on her ears and smell what she is looking for. When she finds us she gets a treat. Sometimes we put a treat in our pocket so it’s easier to find us and also to warm her up to find us later it gives her motivation.

This information underpins our unique speculation of finding a "cheerful medium" for the shot weight. To begin with starting with the lighter ping-pong balls, we were getting short separations given wind resistance on the balls. The 11.32-gram ball, for an occasion, just went an average separation of 15.80 meters. A general, the 28.35-gram ping-pong ball went the most remote, with a mean separation of 29.75 meters. In the wake of including considerably more weight, the separations of the dispatches started to decrease, in the end, closing with a 65.26-gram Ping-Pong ball voyaging an average separation of 24.60 meters. This demonstrates our "glad medium" for our particular launch is around 28 grams for a ping-pong ball estimated shot. To enhance
