There will be a net force from the pressure to push the piston back out. Since gas has mass it can support oscillations and waves. 2.2 Traveling Sound Waves

stored in long-term memory. There are many reasons that we forget information but these can be grouped into four main categories; retrieval failure‚ interference‚ failure to store and motivated forgetting (Loftus 1999). Although there are also many strategies that we can use in order to improve our memory. Retrieval failure is one of the most common causes of forgetting and one possible explanation of this is known as the decay theory. This theory gives an explanation of forgetting as a problem

our nation? Why We Are Who We Are Heritage is our history‚ our different knowledge‚ the values and traditions that we have developed with a combination of genes and culture over time. Heritage‚ whether it be cultural‚ national‚ or just in our families is an endowment of legacies; but foremost‚ heritage is our history. It is responsible for how we came to be‚ it is a very large part of who and what we are‚ and it can determine what we will become. As humans‚ we possess free agency; we can determine

Should we experiment on humans or hybrids? A human-animal hybrid embryo is an embryo made in purpose for experimentation‚ made from human DNA and animal eggs. Scientists have created them so in the future they can produce embryos that survive six or seven days in order to extract stem cells to be used in experiments to help find new treatments for conditions such as Parkinson’s and Alzheimer’s disease. ADVANTAGES DISADVANTAGES It may produce huge benefits for human beings in the future. Blurs

Throughout this experiment there were several reactions that took place‚ and an indicator of such chemical reactions could be seen throughout each one. The first piece of identifiable evidence was present in the first step‚ which was when copper (II) nitrate and sodium hydroxide were combined.

Aim The purpose of this experiment was to plan‚ design‚ fabricate and test the structure of a microfluidic flow structure. Background Microfluidic structures are a relatively new topic of study. While the concept of fluids and the study of the flow of fluids through all sorts of various forms of ducts‚ environments and scenarios have been extensively studied by some of the greatest minds of in history‚ the novelty of microfluidics is not surprising. This is due to the fact that despite the fact

affecting the catalytic decomposition of Hydrogen peroxide Please refer to the additional files for tables/graphs. Aim- The purpose of this investigation is to investigate how certain factors affect the catalytic decomposition of Hydrogen peroxide. I will investigate the effect of altering the mass of catalyst used on the rate of the decomposition of Hydrogen peroxide. Introduction- The decomposition of Hydrogen peroxide is a process by which Hydrogen peroxide decomposes into water and Oxygen
