The short-range character of this 120° order is evident from a global reduction and a broadening of the spin structure factor peaks (Fig. 2d). Particle–hole asymmetry Interactions between itinerant charge and magnetic moments can lead to rich collective quantum phases. One paradigm is doping a...
A particle of mass 2kg is initially at rest on a rough horizontal plane. A force of magnitude 10N is applied to the particle at $$ 1 5 ^ { \circ } $$ above the horizontal. It is given that 10s after the force is applied, the particle has a speed of 3.5$$ m s ^ { - 1 }...
7.14m s-l YX aFigure 4 A particle P of mass 2 kg is projected up a rough plane with initial speed 14 m s-1, from a point X on the plane, as shown in Figure 4. The particle moves up the plane along the line of greatest slope through X and comes to instantaneous rest at the...
projected magnetic reconnection sites at the dayside magnetopause around equatorward and tailward (lobe) boundary of the cusp29,30. The vertical dark blue lines represent the Earth’s magnetic field lines with electron precipitations and FACs. The sun is on the top representing the polar ...
Taking the local radius, instead of the global radius, as R to evaluate the normal contact response is more representative. Examples of local radius for the sand grains in the study are illustrated in Fig. 4. The local radius of each sand particle was evaluated from two perpendicular ...
