Team Experience Working with others has not been difficult for me. Two reasons I believe this occurs are I always challenge myself to do great work and I am also patient with other people. Unfortunately, these are two traits I suspect contributed to a challenging team experience, from which I was able to learn a lesson. I believe these are quality traits, essential for me to be able to do any good group work with other people. As such, I will need to continue to employ them, but in a…

Based on our observations from the Zinc and Hydrochloric Acid Lab, we concluded that the chemical reaction that occurred was exothermic and a single displacement reaction. The experiment consisted of zinc (Zn) and hydrochloric acid (HCl) being mixed in a test tube immersed in water. First of all, bubbles were produced during the reaction. Also, a white powdery substance was produced with properties different from those of any reactant. The bubbles suggest that the reaction was a chemical…

end up fitting when it is heated or the ring might be too big for the ball after the ball is cooled. This might affect our results by thinking that the brass ball contrasted a lot after being cooled by the water when it was really just the thermal energy that made the ring…

Kinetic and potential energy play an essential role in the segments or phases in a heating or cooling graph representing an exothermic or endothermic process. Kinetic energy is the energy of a system that is in motion of the particles in the system. Potential energy is the energy of a system in which it represents the arrangement of the particles of the system. Kinetic energy and potential energy never increase or decrease at the same time, however, when one energy is changing the other remains…

Please 1) describe what is meant by the terms short-wave and long-wave energy, 2) namea specific type of electromagnetic energy for each type, and 3) correctly identify which is associated with the energy emitted from the Sun and the Earth. Short-wave electromagnetic energy has a short wavelength and high energy, while long-wave electromagnetic energy has a long wavelength and low energy. The wavelendth refers to the sine function that describes the eneregy's osicalation through time. Higher…

Design- In this experiment we selected the happy sack to use for our experiment, as this sort of ball doesn’t bounce when dropped to the ground and this then gives us more accurate data for us to compare with the theoretical time. To record the closest accurate time and distance we could get, the equipment we chose to use, were two stopwatches so that we could compare the human reaction times and a tape measure to correctly measure the distance that the ball is going to fall from; which counted…

New Autonomous Unit for a Research and Technology Corporation I am creating a new autonomous unit for the Intuitive Research and Technology Corporation. The autonomous unit being created is a group looking for individuals for a C.A.R.E. day within the company. C.A.R.E. day stands for Creating Awareness Rewards Everyone. We do this CARE day every quarter. We bring in physical therapist, a nutritionist, a health food store representative, and a massage therapist for CARE day. As a company we like…

This experiment’s aim was to find the alcohol with the highest energy output when burnt using specific heat capacity of calorimeters. This data gathered only partially supported the hypotheses stated. There is an apparent trend between the heat energy of the alcohols and the amount of carbon atoms in the alcohols in the graphs shown. The first experiment (first graph) shows the results of the tests with a controlled calorimeter height of 20 centimeters. This means that the calorimeter, rather…

planet is done by using energy? In fact, you are using energy right now. Energy is the capability of producing work. Energy makes a change in an object. Force plays a role in deciding whether an object has done work or not (“Work and energy”, 2015). If the object moves towards the direction of the force, the work done is positive (“Work and energy”, 2015). If the object moves away from the force, the work being done is negative (“Work and energy”, 2015). An important aspect of energy is that it…

Basal Metabolism Basal metabolism is the minimum amount of energy expenditure required per unit of time that is necessary to conduct involuntary bodily functions such as respiration, blood circulation, muscle tone, maintain body temperature, and ultimately maintain life. The human body requires energy to sustain proper body fluids and nutrients that preserve life and health. An individual’s basal metabolism can be determined by finding their basal metabolic rate. According to Respiratory Care…
