II. 2. Hydraulic Jump 2.2.1. purpose 1. to create/generate hydraulic jump 2. To clarify questions about the fluid flow. 3. To determine the slatrility and characteristics of hydraulic jump, performed in the laboratory using impulse momentum and energy equations are specific. 4. to compare between the depth of flow measurements and the results of the theory. 2.2.2. Basic Theory A hydraulic jump occurs when the flow of the flow at a high speed exposure at a low-speed flow that occurs at the…

As I was making my Ecomap I came to realize that my priorities are not completely met and that I might need to change my routine in order to feel satisfied with the goals I want to accomplish in life. As I look at my elements I see that I am focusing my energy mainly in school, which is acceptable since this will help me fulfill my goals of having a successful career one day. School is a positive energy and it brings me satisfaction when I finish a term with a good grade, but at the same time it…

It was anticipated that the smaller blades will produce the most power because the shorter it is, the lighter the mass of the blade will be, therefore it will be easier for the wind to manipulate its movement. Wind Turbines are constructed to be proportionally large because it’s expected to capacitate above the Earth’s surface, where the wind is predicted to be more powerful. Since the blades in the experiment were all at the same level, and the air was pretty much controlled, the large rotors…

The features of action potentials are: threshold, all or none, is regenerative, saltatory conduction and refractory period. The threshold is generated when the membrane of the cell is depolarize around -50mv to evoke the action to occur. Action potential is all or none because is either no action potential or a full amplitude of action potential. We say that action potential is regenerative since a new action potential is generated at each location along the cell membrane. The saltatory…

1. The resting membrane potential is the potential difference across the cell membrane of excitable cells such as nerve and muscle cells. The 3 major factors that establish a resting membrane potential are as follows: (1) Non-diffusible anions: The resting membrane potential is influenced by the presence of large non-diffusible anions (proteins, nucleic acids and organic phosphates) inside a cell. The presence of large non-diffusible anions inside a cell attracts a large number of cations and…

When investigating the mechanisms of neural communication and the impact various drugs can have on this its important to take into consideration what these actually mean and whereabouts in the body are the main components. The word neural communication consists of how neurons communicate with each other through their physiological process, and drugs consist of chemicals, substances or medicines that have a physiological and/or psychological effect on the brain and body. Within this essay I will…

Energy can be potential or kinetic. Radiant energy is a form of Kinetic energy. Movement of atoms, molecules, objects, waves, substances referring to a Kinetic energy. There are many different forms of kinetic energies like sound, motion, thermal energy, electrical energy. Nevertheless, there would be no life on Earth without radiant energy. What is radiant energy? The energy of electromagnetic waves and gravitational radiation is radiant energy. Radiant energy is the result of a change in…

Aim Simple Pendulum Experiment The aim of the experiment was to determine the effects of two factors (the length of a pendulum and the hanging mass of a pendulum) on the period of oscillation of the simple pendulum and to determine the value of g, the acceleration due to gravity. Apparatus Retort stand String Meter ruler Table Standard hex nuts (as suspended mass) Stopwatch Labelled Diagram Illustrating setup Method Experiment A: The simple pendulum was assembled using a retort stand,…

speed up nerve impulses. (Tortora pg. 407) An axon that is surrounded by myelin sheath, whether in the central nervous system (CNS) or the peripheral nervous system (PNS), is said to be “myelinated”, while the bare axon is “unmyelinated”. Action potentials travel more rapidly and further in distance along a myelinated axon, this is because they travel by salutatory conduction. This is when the impulse at the first node generates currents that open gated channels…

colour change) causes these ion channels to open producing a change in the membrane potential of the receptor cell/s resulting in depolarisation. Once a threshold level of depolarisation is reached, approximately 15mv, the receptor cell stimulates the production of action potentials that are conducted along the membrane of a nerve fibre towards the central nervous system (the brain and spinal cord). An action potential occurs like this: 1. A sensory nerve cell detects a stimulus (e.g. heat,…
