Earthworm Action Potential Conduction Velocity: The Effects of Various Salts and Neurotransmitters When it comes to performing action potential experiments within the lab, the giant nerve fibers of an earthworm are an important tool for success. They yield a high success rate when compared to other organisms (Kladt, Hanslik, & Heinzel, 2010), and provide a more ethical means of testing how various neurotransmitters affect action potentials, instead of direct use on humans for pharmaceutical…

fluid flow. Fluids can flow steadily, or be turbulent. In steady flow, the fluid passing a given point maintains a steady velocity. For turbulent flow, the speed and or the direction of the flow varies. In steady flow, the motion can be represented with streamlines showing the direction the water flows in different areas. The density of the streamlines increases as the velocity increases. Fluids can be compressible or incompressible. This is the big difference between liquids and gases, because…

egg-dropping requires knowledge of free-fall physics. The most basic formula to know is v = d/t, or velocity is equal to the distance divided by the elapsed time. In the test simulation, the device is dropped at a distance of 75 feet or 22.86 meters, and the average elapsed time is 2.223 seconds. Using these two values, substituted into the formula, the velocity is determined to be 10.2834 meters per second. Velocity is a vector quantity with direction and magnitude. In the case of the device,…

During my experiment, the same human figure is used. As a result, the weight which is one of the external forces acting on the ski jumper remains constant. Moreover, the velocity of a figure is controlled constantly as 2.5m/s. In addition, the drag coefficient, the area and the density of the air have the same values. These mean it is available to control two main external forces acting on the ski jumper. As a result, we…

Clarkson said “It 's not how fast you are travelling which causes serious injury in a car crash, but it 's how fast that you stop.” During a crash the severity depends of how fast you break. Velocity, acceleration and Newton’s three laws play a vital role during a car crash. Sir Isaac Newton discovered the three laws of motion in 1686. Newton’s first law, or inertia, states that “an object at rest stays at rest and an object in motion stays in motion, with the same speed and in the same…

economic equation of exchange. MV=PY where Money supply/Quantity of money. On the other hand, V=Velocity of money circulation, while P and Y represent General Price and Real national income respectively. The according to Milton Friedman, the equation means that the total value of the quantity of money multiplied by velocity equals the money value acquired at the output. Regarding the equation of exchange, Velocity is presumed to remain constant. On the other hand, changes in M produce a similar…

in this case the force would be the foot kicking the ball. When the ball is kicked up with the force to go over the opponents head this will form an upside parabola shaped arch. When the ball hits its highest point , which is the max point, the velocity is zero and then the ball starts to descend back down this is due to gravity acting on the ball , by this point there will be a player waiting to catch it with their body. The same projectile concept is invoveled when players do throw- ins…

The Difference in Seed Drop Velocity Between Sugar Maple and Norway Maple Seeds Authors: Vanessa Alan, Aubrey Bianco, Micayla Boots, Erin Slason BI 101.35 Dr. Kotila Introduction: The question on how plants and ultimately seeds travel from one place to another was just one of the many research questions asked by Charles Darwin. Darwin was an experimentalist who proposed many questions and performed corresponding experiments that tested multiple hypothesis. For instance, Darwin wanted to…

It has units of seconds. A sedimentation coefficient of 1x10-13 seconds is defined as one Svedberg, S. Conclusion: • The sedimentation velocity of a particle is directly proportional to its phase. • A dense particle moves more rapidly than a less dense one because the opposing buoyant force is smaller for a dense particle. • The sedimentation velocity depends also on the density of the solution (ρ). Particle sinks when vρ1. Relative Centrifugation Field:…

It explains that an object subjected to an external force will change its velocity and that force is equal to the change in momentum, which can be translated to mass times velocity per change in time (or f=ma). An example of this law is pushing a heavy ball harder to get it to move as fast as a small one. If you want to indulge into more of the math side of it, then think of…
