F40 BMA Tutorial 4 1. A man is driving at 120 km/h along a straight road and he looks to the side for 2.0 s‚ how far does he travel during this inattentive period? [66.7 m] 2. A horse canters away from its trainer in a straight line‚ moving 160 m away in 17.0 s. It then turns abruptly and gallops halfway back in 6.8 s. Calculate (a) its average speed and (b) its average velocity for the entire trip‚ using “away from the trainer” as the positive direction. [10.1 m/s; 3.36 m/s]

Digestion define as a process where foods been breaking down by enzymatic action in the Gastrointestinal tract (GI tract) into nutrients in preparation for absorption. GI tract is the flexible muscular tube from mouth to anus. The digestion of carbohydrates begin in the mouth‚ where an enzyme‚ salivary amylase (α-amylase;ptyalin) starts to breaking the polysaccharides (starch) into short polysaccharides (dextrin). Dextrin is a partial degradation of starch‚ shorter chains of maltose units. Salivary

“A mouth is a part of the body where people use mechanical digestion and use their teeth to break down their food. With the help of saliva produced by the salivary glands‚ which produce enzymes‚ food is able to be broken down further. This is also the place where ingestion takes place” “What are enzymes” “Enzymes are very efficient catalysts for biochemical reactions. In the mouth there’s an enzyme that will help your food undergo chemical digestion” “What is it” “It is amylase. Which help digest

Does the amount of time that orange juice is swished in a human mouth affect the pH of the saliva‚ which could inhibit the digestion of the starches in the orange juice? Hypothesis: The longer 2 mL of orange juice is held in a test subject’s mouth‚ the greater the ability of the test subject’s saliva will become to break down starches. Dependent Variable: pH of the saliva. Independent Variable: time that the juice is swished in the mouth. Controlled Variables: Orange juice only. The

Lipid Digestion The process of mastication is our only conscious act in the digestion of the foods we consume. After that‚ it’s out of sight‚ out of mind; but should it be? What does it take to transform that last swallow into the energy our body needs to sustain itself? In the case of lipid digestion‚ the real magic occurs throughout the gastrointestinal tract with a synergistic collaboration from the accessory organs: the liver‚ gallbladder and pancreas. Understanding the whole process of digestion

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
