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…

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,…

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,…

I am Thalamus according Scholapedia, am a small part of the brain located between in the middle and the center of the brain and I’m connected to the cerebral cortex and the midbrain thru nerves. I have many functions, but my main function is to regulate the voluntary motor control, the consciousness whether a person is asleep or awake (the sleep cycle), sight, sound, taste, and touch. I’m composed of 3 different groups of cells; the sensory relay cell or nuclei which receive sensation or…

Charcot-Marie-Tooth (CMT) Disease Charcot-Marie-Tooth Disease which is also called CMT. It is said in National Institute of Neurological Disorders and Stroke “That the physicians Jean-Martin Charcot, Pierre Marie, and Howard Henry Tooth. In 1886 Charcot, Marie, and Tooth discovered a group of progressive disorders that affects the peripheral nerves” (NINDS). They still consider this disease to being rare in the United states. The estimated amount of people who are diagnosed is fewer than 175,00…

Instead, potential energy is stored in things like ropes until the catapult is ready to fire, when the energy transfers to the projectile and become kinetic. The three primary energy storage mechanisms are tension, torsion, and gravity. The catapult has proven to…

paper, have you ever wanted to learn about the physics of rollercoasters? This research will explain how potential energy is converted into kinetic energy throughout the roller coaster. Two variations of roller coasters will be built. The roller coasters will be used to compare how the marble’s energy is affected by the hills, turns or loops of each roller coaster. Now let’s test their potential. The concept of a roller coaster can be dated back as far as the 1400’s. According to research, the…
