change in magnetic flux (figure 2). This force is dependent on: The size and shape of the conductor and magnet The strength of the magnet (μ) The conductors conductivity (σ_c) The distance between the conductive surface and the magnet (d) The velocity of the magnet (v) According to Faraday’s law, discovered in 1831 by Michael Faraday, this alteration in flux produces electromotive force (EMF) and eddy currents inside the metal. (Meerman, 2014) This force is the retarding force that is…

it from increasing Refractory Periods in the 2nd experiment to determine the refractory period 2 stimuli were send to the nerve by decreasing the interval between them both every time at 200mV . Conduction Velocity the third experiment was used to measure the conduction velocity of the nerve a double voltage of the 2nd experiment was entered in the stimulator panel . there was 2 data recorded proximal channel from the nearest electrode and the distal channel from the further electrode.…

Anxiety and Movement Serene Velocity by Ernie Gehr and So Is This by Michael Snow are two films built from constraints that seem to rely on similar understandings of motion and, in these understandings, evoke similar emotive responses. In these two films, we are presented with velocities. These velocities are causes of tension, frustration, and anxiety. Serene Velocity was filmed in one night in 1970 in a hallway of a building at the University of Binghamton. In a way, the film was made before…

own opinion as to which caliber makes the perfect hunting round. However, the reality is that there is no one size fits all when it comes to hunting. Factors like the size of the animal being hunted, the distance the round needs to cover, and the velocity of the round all need to be taken into consideration before deciding which round is perfect for you. With that said, .30 caliber rounds are the most widely used hunting rounds North American big game hunting. There are many different rounds…

a table tennis table to aid serious table tennis players. The behavior of the balls before and after collision with a table, at various initial speeds ranging from 15 to 115 km/h, was captured using high-speed cameras. Velocity and spin rates before collision, along with velocity and spin rates after collision, were computed to calculate the coefficients of restitution and friction. Based on the computed variables, the post-collision trajectories…

opposite of reality and in the physics world, it makes complete sense. As you may have guessed, the objective in this sport is to get down the track at a faster time than your opponents. To do this, you obviously need velocity to achieve that goal. The only form of velocity in the sport of luge is gathered by gravitational force. However, there are two main…

rapidly. Its impact on velocity distributions which become highly uneven with corresponding large values of energy coefficient (α) & momentum coefficient () and fluid flow may fail completely to flow the channel walls. Several experimental studies carried out before to find out the losses in the abrupt expansion (Hinds 1928; Formica, 1955; Smith and Yu, 1966; Mazumdar, 1967; Nashta and Garde, 1988). The channel transition ratio (B/b) has a significant influence upon the…

In order to find an accurate brittleness and stiffness for a rock, Rickman et al. (Rickman) has come up with a method that has been used frequently. In order to determine the brittleness index of a certain section of rock, Rickman advises the use of two rock parameters: Poisson’s ratio and Young’s modulus (Rickman). The ideal brittleness is a low Poisson’s ratio and a high Young’s modulus. A low Poisson’s ratio indicates the rocks capability to fracture when stress is applied and a high Young’s…

acting on the object. With several calculations and graphs to illustrate our results, we shall strengthen implications of the relationship between force, mass, and acceleration. Introduction Mass is defined as. Acceleration is defined as change in velocity over a time interval. Mass of an object and acceleration, by definition, are in fact independent of each other, so how do they relate? If you consider a boulder and a penny…

Faster-than-light travel (FTL) refers to matter travelling at a faster speed than light (c). In a vacuum, this speed is known as 2.998 x 108 meters per seconds. Based on the Theory of Relativity, it is known that objects with a mass cannot exceed the speed of light as they require infinite energy due to the increasing amounts of energy required for continuous acceleration (PhysicsLink, 2017). However, matters without mass, such as photons, can reach this speed (PhysicsLink, 2017). Nevertheless,…
