velocity is the value at the first light gate‚ so the Suvat equation returns to the original a=(V²-U²)/(2s). In this experiment the dependent variable will be velocity of the golf ball as it travels through the light gate and as the drop height changes‚ this is the variable that will be measured. The independent variable will be the height the ball is dropped from as this is the variable that will be changed.

CHEMICAL CHANGES IN THE LARGE INTESTINE AND DETOXICATION • After digestion and absorption in the small intestines‚ the semi liquid residue is passed into the large intestines. • There are no enzymes to act on the residues in the large intestines. • Only a very small amount of viscous‚ slightly alkaline fluid containing large amount of mucin is contributed by the mucosal cells of the colon. • There are normal intestinal microorganisms which disintegrate the organic residues into

eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species combining

A Ripple of Change Violent storms‚ rumbling earthquakes‚ tsunamis‚ and a global change in climate are some of the signs that we are about to enter the so called “changing world” – a world that is full of mystery‚ full of sorrow‚ and full of obstacle that the humankind is endanger for its existence. But if we look back to the recent years‚ the world is not like this. It is full of joy‚ abundant in its resources‚ and above all‚ our life was not at risk. This only proves that the world is so unpredictable

Physical and Cognitive Changes in Late Adulthood What are some examples of the physical and cognitive changes people go through when they enter late adulthood? It is a proven fact that as we age our body goes through many physical changes. Some physical changes our body goes through in our late adulthood are‚ our vital organs gets weaker less efficient at their job. Our immune system becomes more susceptible to the common flu and diseases. Our five senses get weaker causing us to require help

Photocatalytic degradation of methylene blue using TiO2 nanoparticles Nupur Mittal Chemical Engineering‚ IIT (BHU) Varanasi. Abstract: The aim of this research is to reduce the pollution caused by methylene blue dye in waste water coming from textile industries. For this purpose‚ TiO2 nanoparticles are made as they show good photocatalytic activity in degradation of dyes into harmless products. Synthesis is done using titanium butoxide and 2-propanol. The particles formed were a little larger

Most people might believe that putting mentos in diet coke is a chemical change‚ but it is actually a physical change. This is because the pieces that caused the reaction are still there‚ but they have just been rearranged. This also means that changing some of the factors in this experiment might cause another physical reaction to occur on a smaller or even larger scale.(Science Buddies) What you see when mentos are put into diet coke is that the coke spews out of it’s container once contacted

Alloy - An alloy is a substance made by melting two or more elements together‚ at least one of them a metal. An Example: Examples of alloys include brass‚ bronze‚ 14k gold‚ and sterling silver. covalent bond - A covalent bond is a chemical link between two atoms in which electrons are shared between them. An Example: There is covalent between the oxygen and each hydrogen in (H 2 O). Each of the bonds contains two electrons - one from a hydrogen atom and one from the oxygen atom. Both atoms
