1. A particle P moves on the x-axis. The acceleration of P at time t seconds, t≥0 ,is (3t + 5) ms-2 in the positive x-direction. When t =0, the velocity of P is 2 ms-' in the positive x-direction. When /= T, the velocity of P is 6 ms-' in the positive x-...
Observed rapid variations in flare emissions imply that reconnection is non-steady and a time-varying electric field is present in a reconnecting current sheet. This paper describes exploratory calculations of charged particle orbits in an oscillating electric field present either at a neutral plane or...
