Acceleration of a particle moving inx−yplane varies with time t as.→a=(ti+3t2j). Here a is inm/s2and t in sec. At timet=0particle is at rest origin. Mass of the particles is1kg. Find the net work done on the particle in first2sec. ...
Depending on the sign of the change in the field in time or on the direction of motion of the magnetic inhomogeneities regular acceleration will lead either to an increase or a decrease in the particle energy. If both of these processes take place on the average at more or less the same ...
A dynamical time-dependent model of particle acceleration at coronal mass ejection (CME) driven shock waves is presented. We consider first a one-dimensional model applicable to shock waves of arbitrary strength. The model includes the determination of the particle's injection energy, the maximum ...
The acceleration of a particle at time t seconds is given by a=6t. Given that v=10 when t=0 and that x=7 when t=0 find x when t=2? Given a velocity time graph how do you determine when the object is moving at the lowest speed, is it when V=O or when the ...
A particle moves along the x-axis in such a way that its acceleration at time t for t≥q 0 is given by a(t)=4cos (2t). At time t=0, the velocity of the particle is v(0)=1 and its position is x(0)=0.Write an equation for the velocity v(t) of the particle. 相关知识点...
The most powerful persistent accelerators in the Universe are jetted active galaxies. Blazars, galaxies whose jets are directed towards Earth, dominate the extragalactic γ-ray sky. Still, most of the highest-energy particle accelerators probably elude d
In the solar system, our Sun is Nature’s most efficient particle accelerator. In large solar flares and fast coronal mass ejections (CMEs), protons and heavy ions can be accelerated to over ~GeV/nucleon. Large flares and fast CMEs often occur together. However there are clues that differe...
A particle moving along x-axis has acceleration f, at time t, given by f=f0(1−tT), where f0 and T are constants. The particle at t= 0 has zero velocity. In the time interval between t= 0 and the instant when f= 0, the particle's velocity (vx) is A12f0T2 Bf0T2 C12f0...
