IB Physics Internal Assessment Andy Tang Research Question In this internal assessment, I am given a cantilever to find the physical properties of it. I decide to investigate the relationship between the force I act on one side of the cantilever and the maximum acceleration the tail can reach. This experiment will be also showing the elasticity of the cantilever. Since I pull down one side of it and fixed the other side, when I cut the string, it will bounce up and down until all the internal

blood/Measurement of the amount of solute concentrate. b. What is the nephron’s role regarding osmolarity? Filtration, reabsorption & secretions c. What two factors regulate body fluid osmolarity? - Formation of a medullary osmotic gradient - The amount of ADH (antidiuretic hormone) present at the collecting ducts. d. Describe the collecting duct role relative to urine concentration. Depending on the body fluid

differences in soil moisture can significantly affect the generation and upkeep of drylines. Since soil moisture and vegetation decrease from east to west latent heat flux also decreases from east to west. This contributes to a zonal dewpoint gradient. Temperature gradients can exceed 10 K (1 km)-1 or be more diffuse at 10 K (100 km)-1 . Dryline formation can sometimes be associated with a surface pressure trough. The dryline does not a pressure trough nor in

Physics Lab Report SIXTO LEONEL GUANO ROBAYO [ Group S-13] 05/12/2015 MEASURE THE POTENTIAL DIFFERENCE (V) AND CURRENT (A) VALUES BY USING A VARIETY OF RESISTORS, REMAINING CONSTANT EMF TO FIND OUT ITS INTERNAL RESISTANCE. Academic year: 2015-16 Title Measure the potential difference (V) and current (A) values by using a variety of resistors, remaining constant EMF to find out its internal resistance. Introduction “Batteries and cells have an internal resistance (r) which is measures

Typical as-plasma-sprayed hydroxyapatite (HA) coatings along the thickness have an internal gradient structure and chemistry [Rs]. The thickness gradient structure extends from amorphous base to crystalline surface. During plasma spraying, the amorphous calcium phosphate (ACP) base is formed by rapid cooling of external molten part of flying HA spray-powder particles upon impact on cold substrate. If the flying HA spray-powder particles are heated in plasma jet above 1843 K, but below 1973 K, the

A fetus might not be considered a “person” right after birth according to the gradient view, but it is considered a human being. Once the baby is out of the mother’s body it can start breathing and that is when their life is considered to have started (Abortion article Pg. 76). The gradient view of personhood expresses human evolution by degrees (Abortion Article pg. 84). This means that according to this view, the older a person becomes

Introduction Evolution and innovation are two of the most important factors in the development of aerospace design. When faced with a design problem the decision has to be made whether to develop the current idea, or whether to explore a new idea. The decision chosen will usually be a mixture of both. Brief History of Optimisation Optimisation is an extremely old method and was used as far back as when Newton used it to calculate maximum and minimum values for functions. One of the first times that

Discuss the role of proteins in cell membrane transport essay plan Cell membranes are surrounded by a phospholipid bilayer that provides a semipermeable barrier for cells, separating the cytosol from the extracellular environment. Phospholipids are ampithatic, meaning that they have a hydrophilic head and hydrophobic tail, which causes the heads to face outwards towards the water and the tails inwards, creating the bilayer [figure 1]. Small hydrophobic molecules such as O2 and CO2 and small uncharged

the first time being when they were absorbed into the bloodstream from the digestive tract after a meal. https://www.khanacademy.org/test-prep/mcat/organ-systems ACTIVE TRANSPORT: Active transport can move a solute against an electrochemical gradient and requires energy to transport the solte for metabolism. Transport that is coupled directly to an energy source, such as the hydrolysis of adenosine triphosphate (ATP), is termed primary active transport. A good example of this is the sodium-potassium

survive in. In this part of the lab we measured the temperature of water from each section and recorded that number also. We did this by simply pouring the water from each section into 4 different test tubes and placing a thermometer in each. Ph Gradient: We proceeded to fill and measure the tubing as we did in the previous step. After we had our equipment set up and the tygon tubing filled with water and adult brine shrimp we removed 1ml of water from each end of the tygon tubing and replaced it
