The problem of effective transform of Poynting flux energy into the kinetic energy of relativistic plasma outflow in a magnetosphere is considered. In this article we present an example of such acceleration. In order to perform it, we use the approach of ideal axisymmetric magnetohydrodynamics (MHD...
Example 2: A body moves along the x- axis according to the relation x=1–2t+3t2, where x is in meters and t is in seconds. Find the Acceleration of the body when t = 3 s Solution: We have: x=1–2t+3t2 then; Velocity v=dxdt=−2+6t Acceleration: v=dvdt=6ms2. (We see...
When the vehicle is traveling on a banked road for example, a component of the vehicle weight will act as a lateral force at the center of gravity, as shown in Fig. 4.1. This section will look at the vehicle motion when the lateral force, Y, acts at the center of gravity. Sign in...
The application of accelerators toradiocarbon datinghas been deemed a revolution in archaeology. This is partly because of the much larger sample throughput possible, but also because the integrity of the samples can be more closely controlled. For example, a single carbonized seed can be dated, ...
Dark energy accounts for about 70% of the total mass-energy of the universe. In contrast, dark matter accounts for about 25% of the universe’s mass-energy, and ordinary matter only 5%. DOE Office of Science: Contributions to Cosmic Acceleration & Dark Energy ...
When you're in an elevator, for example, as the elevator accelerates upward or downward you feel as if your weight is changing—you feel heavier when the elevator is accelerating upward, and lighter as it accelerates downward. Stand on a bathroom scale in the elevator, and you'll see that...
in Australia,many teachers remain confused about what the teaching of thinking involves,how it might best be achieved and/or how it affects students’ learning and achievement(Oliver,Venville,and Adey,2011).This is an issue internationally,for example(Zohar)Degaini, and Vaaknin(2001) found that...
Instantaneous acceleration (at a precise moment and location) is given by the limit of the ratio of the change in velocity during a given time interval to the time interval as the time interval goes to zero (see analysis: Instantaneous rates of change). For example, if velocity is expressed...
Velocity, quantity that designates how fast and in what direction a point is moving. A point always moves in a direction that is tangent to its path; for a circular path, for example, its direction at any instant is perpendicular to a line from the point
