Steroid Lab Report

Purpose: Weighing objects. Figuring out the density with an object by calculated volume and Archimedes’ Principle.

Objective: Using a marble launcher, launch marbles from different angles with different forces to find the maximum height and the velocity as it leaves the launcher. Using different variables and results to determine how the different angles and amounts of force effect the variables. With this data show the effect the forces cause in 1-D and 2-D motion, as well as in the X and Y directions. This is done through kinematic equations and calculations.

Aim: The aim of this experiment is to see which ball is better quality for bouncing and what is a lot more reasonable for price and size.

Section Heading: The reason I think the golf ball will go the farthest is because it has the most density and density means “to have the degree of compactness of a substance.”I believe the tennis ball will go the second farthest because it has almost little density and it has no core at all and it's hollow.When the ball is hit with the most density it will give it the weight and power to travel great distance but unless the ball has to much weight it won’t go far.The baseball has the least greatest density so I gathered information

To determine whether the height at which a marble is dropped affect the size of the crater.

Introduction: Accuracy and precision were the major aspects of the lab. Accuracy is how close the average of the measured values are to the actual value. Precision is the closeness of repeated measurements. In the lab, the aim was to get as close as possible with both accuracy and precision when determining the mass and volume of the spheres. The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. The volume is determined by measuring with a ruler and by water displacement. The standard

Hypothesis: No the size of the crater and ejecta will change because it will have lighter and harder impacts on the surface.

In the movie when the crew was on the crater drilling, nothing was coming out of the hole. When there is drilling taking place the rock or dirt needs to be displaced into the surrounding area. In the movie nothing came out of the hole during the entire drilling process. There was almost no gravity on the asteroid to be able to hold the remnants and dust in the hole being drilled.

Massive boulders rained from the sky; each breaking as it struck the ground. Debris scattered and

By the 5th century C.E. the western roman empire crumbled. There have been many historians with serval different theories such as military failures, almost unbearable taxation, natural disasters and religious change. The roman empire did not completely collapse as the eastern side known as the Byzantine empire lasted a fair amount of time after the fall of western Rome. One of the most popular theories and possibility the most straight forward is a mass amount of military failures. Invasions by barbarian tribes like the goths, Visigoth king Alaric raided the city of Rome and this may have made Rome look weak as it is believed to be raided several more times.

How exactly the asteroid damaged the Earth remains unclear, but the power released by such an impact is unquestionable. Effects possibly include reduced sunlight over a period of several months which possibly led to the decline or even total halt of primary production (via photosynthesis). One of the dominant signatures of the extinction at the KT boundary was the low activity of primary production, the possibility of reduced sunlight is high (Schulte et al. 2010) . Even if the primary production proved to be on a decline when this impact occurred, there is still some uncertainties as to where exactly the impact hit. This was why asymmetries in subsurface features of the Chicxulub crater were observed via geophysical methods were analyzed and it was calculated from estimates that the

hit Earth are found to be great discoveries. These small space rocks that have been chipped off

“I don’t think you should support the death penalty to seek revenge. I don’t think that’s right. I think the reason to support the death penalty is because it saves other people’s lives” (Bush). Capital punishment is one of the most controversial topics in the American society and is also one of the topics most people feel very emotional about. Everyone feels that their views are correct because there are many pros and cons to either side. Although some people believe the risk of executing the innocent is too great, the use of capital punishment has greatly impacted our society in a positive way because of its deterring

Gerta Keller, professor of geosciences at Princeton University, has recently conducted research on the Chicxulub asteroid in which she analyzed new core samples taken from the asteroid site (Botzer 2004). These samples indicate that the impact that occurred at Chicxulub actually predated the mass extinction of the dinosaurs, which occurred at the Cretaceous-Tertiary boundary about sixty-five million years ago. Keller claims that the Chicxulub impact occurred approximately 300,000 years before the extinction (Keller 2004). Although previous researchers estimated that the Chicxulub asteroid was the cause of the extinctions, there had always been doubts about the exact age and size of the crater, and about the origin of the “mega tsunami deposits” that were located within the crater (Keller 2004). The focus of Keller’s recent research was on finding some answers to these questions. To do so she analyzed Cretaceous limestone, dolomite, and anhydrite deposits as the site of the Chicxulub crater (Keller 2004).

Last year during winter, my friend and I decided to spend our day in Chicago. It was a cold, brisk day and it started snowing. We had our warm coats on, yet we were still freezing. On our way to get to the train station, we saw a homeless man, he had no coat on and he was shaking from the cold. I looked at him, and suddenly I felt his pain. It was a strange moment and I wanted to feel the cold that he was feeling, I wanted to be in his shoes so I took my coat off and I offered it to him. My friend stopped me and he gave the homeless man his coat instead. In that moment, there was a smile on the old man’s face, he wore the coat immediately, and he gave us his blessings. After reading both, the article “ Baby in The Well”, and “ The Empathy Exams”, this occurrence immediately came to my mind. While reading about empathy, I felt déjà vu, and I remembered how I empathized with the homeless man by the train station. In the article,
