of the actuator disk. Fig 2. Actuator disk model of a wind turbine (Xiaomin Chen and Ramesh Agarwal, 2014) The axial induction factor a, since the actuator disk induces velocity in the stream tube, can be expressed by: a=(U_1-U_2)/U_1…

penalty mark at 0.6x0.6 target at the full size goal post according to their self selected approach angle (direction of the kick was 0°). Result revealed that there is no significant difference between the changing angles of strike and accuracy or the velocity of the ball. Pelvic rotation was significantly greater than 45° and under 60°. Penalty kicks of the recreational soccer player was not improved by altering the angle of approach to the ball, however widening the approach angles of athletes…

created in both the racquet and ball (Dyer, 2001). The ideal situation, and what happens if a sweet spot is hit, is these vibrations move back into the tennis ball, giving the ball a higher kinetic energy, and thus a higher velocity, as kinetic energy is proportional to velocity. This also makes the hit feel better, as less of the vibrations travel into your arm. There are four main points of interest on the racquet that are described in detail. The dead spot, although not a sweet spot, is…

P= mass * velocity = mv = 0.00745kg * 381 m/s = 2.838kgm/s Assuming that all the momentum is transferred to the T800,it will change the momentum of the T800 by a certain amount:we can call this Delta P(DP).We can then work out what velocity each bullet would normally impart,which will refer to as Delta V(DV).We need the wieght for T800,which is never stated.But it can ride…

for sure that the velocity of the child, at least its direction, is constantly changing, because every moment we look at the situation, the child is moving in a different direction. This is sketched in Fig. 4.6(a). Can we figure out how the velocity changes, provided that the speed is constant, that is, v1 = v2 = v and the distance between the child and the carousel center remains constant, too? First we can qualitatively see from point 1 to point 2 that the change of the velocity is pointing at…

The goal of this experiment was to determine the Michaelis constant (Km) and also the maximal velocity (Vmax) and the inhibition of alkaline phosphate. In order to accomplish these goals, 5 samples were used. Each sample contained different volumes of 0.2 m MPNPP (p-nitrophenylphosphate) and 0.2 M Tris-Hcl at a pH of 8.0. To each sample 0.2 mL of the enzyme studied (Alkaline Phosphatase) were added upon insertion on the spectrophotometer apparatus. With intervals of 20 seconds their absorbance…

storage, mining and analyzing data. • Velocity: Big Data Velocity deals with the pace at which data flows in from sources like business processes, machines, networks and human interaction with things like social media sites, mobile devices, etc. The flow of data is massive and continuous. This real-time data can help researchers and businesses make valuable decisions that provide strategic competitive advantages and ROI if you are able to handle the velocity. Professionals suggest that sampling…

that compete with substrates to bind with the enzymes, this can result in low velocity of enzyme and the product formation. While non-competetive can bind to another active site of the enzyme incrasing the velocity and substrate concentrations. These are measured by using Michaelis-Menten Kinetics formula, the equation measures the substrate concentration verses the velocity of an enzyme to show the relation between velocity and substrate concentration. However when enzyme reaches it maximum…

fluid flow in the fuel cell was laminar due to the low flow velocities and the small size of gas flow…

In this video olympic swimming athlete Bennet Clark demonstrates a race start with the help of his Cal swim team coach and the laws of physics! Clark’s dive can be related back to Newtons 1st law of motion. This law states that “An object at rest stays at rest and an object in motion stays in motion with the same speed and direction, unless acted upon by an unbalanced force” In this video the athlete is at rest when he is first on the starting block. He is being acted upon by normal force…
