it fun‚ exhilarating‚ and decently scary you also have to think about the scientific principles. As these will all be defined by Oxford’s dictionary. One of the most common scientific principles is kinetic energy. Kinetic energy is energy that an object possesses by virtue of being in motion. Kinetic energy increases as motion increases during the roller coaster ride. Potential energy is the energy of a body or a system with respect to the position of the body or the arrangement of particles in the

I will now look how I perceive colour on the percept. When analysing sensory perception I explained the process of how the eyes see the percept through wavelengths of light‚ which is transmitted at different wavelengths and frequencies. The main source of light would be sunlight. The scale of the wavelength and frequency for light determines the colour seen‚ as every colour has its own wavelength and frequency. When perceiving colour the spectrum of the wavelengths stretches from short wavelengths

Unit 11: Kinetics and Equilibrium Activated complex: an intermediate state that is formed during the conversion of reactants into products‚ the structure that results at the maximum energy point along the reaction path. Activation energy: a chemical reaction is the difference between the energy of the activated complex and the energy of the reactants. Catalyst: substance that increases the rate of a chemical reaction by reducing the activation energy‚ but which is left unchanged by the reaction

Article summary The purpose of the article is to explore the need and advantages of conducting community based research with women of colour in the United States. The authoritative knowledge that these women can provide about their lives and their health could form the basis of collaboration between researchers and participants and lead to successful strategies to improve the health of African American women. The article provides the goals for improving African American women’s health before investigating
