30m/s due north. Meanwhile‚ acceleration is definitely not the same as velocity or speed. Acceleration is the change in velocity in a certain amount of time. The factors affecting the terminal velocity of a falling object include: its mass‚ its surface area‚ the viscosity of a liquid and the height of where the object is dropped. In his First Law‚ Newton explained the effect of a net force‚ greater than zero‚ upon an object at rest. In his Second Law‚ Newton explains the effect of a force upon a moving

Exploring Enzymes - Ground-Up Tissue Activity Abstract Our experiment looked at how increasing the surface area of a substance affects the amount of bubbles created due to the presence of the enzyme catalase. The experiment used two pieces of fish‚ one whole and one ground up‚ which were then covered in hydrogen peroxide. This method allowed us to observe the catalase in ground up fish break down the hydrogen peroxide at a quicker rate than in the piece of fish left intact. This was determined

find out if surface area affects reaction rate‚ and this experiment proved that surface area in fact does affect reaction rate. My experiment used a berocca tablet that was either cut into sections or left whole‚ the smaller fractions had a larger surface area as there was more area to cover‚ the pieces were then put into water to see what sized tablet reacted to the water the fastest. My hypothesis was supported as it was proven that the smaller pieces which had a larger surface area were much quicker

the Ratio of Surface Area to Volume on Transformation Efficiency in Escherichia coli K-12 Eliana Pouchard‚ Steve Teng‚ and Cameron Wong Department of Microbiology & Immunology‚ UBC In the process of transformation‚ bact eria take up DNA fr om the environment through their cell wall. To induce competence in the cells‚ the DNA for uptake must first attach to the cell surface prio r to passing throug h the membrane. Previous studies on the effect of surface area on transformation

apply before an area can be considered safe? A safe area according to the definition from the Encarta is summed up as an area where one can find refuge and safety‚ while living in security‚ (Encarta. 2007). Would you consider the Ryerson Campus area to be safe? This depends on a certain individual ’s bias which is based on the gender and age of that individual. Another factor that comes in to play is the time of day you are viewing the area‚ different opinions may be generated on an area if it were daytime

through several ways‚ like diffusion? Aim: To plan and carry out an investigation to show the relationship between volume/Cm3‚ surface area‚ and diffusion using agar cubes measured in time/s; and to demonstrate‚ using diffusion‚ why the size of cells is limited‚ keeping the room temperature and pressure constant. Hypothesis: I expect to find that when the surface area to volume of a cell reaches a certain level‚ diffusion alone won’t be able to supply the cell materials needed‚ and as single-celled

The Aspire of Importing and Exporting _______________ gave this class a chance to help them figure out which floor matting will help a cargo box stop from moving. One factor that is used is friction. Friction happens when two surfaces rub against each other and may cause heat. Also there are four types of friction which are static‚ sliding‚ rolling‚ and fluid friction. The company needs the class to find out what type of flooring is best to use to stop a cargo box from moving. They have game

piece must be kept the same in each experiment primarily because they affect the surface area of the piece‚ and varying surface area could have a great effect on the rate of osmosis. This is because in an experiment where the potato chip has a large surface area‚ there is a larger area of partially permeable membrane and therefore more opportunity for water particles to pass through. I will keep the surface area the same by keeping the mass and length of the potato piece the same in each

concentration of Hydrogen Peroxide Hypothesis I predict that the breakdown of Hydrogen Peroxide will be quicker when the surface area is increased. If you cut the same size piece of potato into smaller pieces‚ I believe‚ the breakdown will be faster. I predict that an increase in surface area will result in an increase in kinetic energy. Since the size of the area increases‚ I think that more oxygen will be released from the Hydrogen Peroxide and Catalyse. We will be measuring the
