Un bloque de masa m = 3 2 Kg desliza por un plano inclinado sin friccion desde una altura h = 12 m. Llega a una superficie horizontal por la cual sigue deslizando, pero esta vez existe un coeficiente de friccion cin´etica entre el bloque y la superficie con valor µk = 3 10 . Despues de recorrer una distancia horizontal L = 5 m, el bloque colisiona con una caja de masa M = 5 2 Kg, inicialmente inmovil, y queda completamente incrustado en ella. El conjunto de caja y bloque continuan deslizando por la superficie horizontal, con el mismo coeficiente de fricci´on cin´etico, una cierta distancia adicional X, hasta quedar detenidos completamente.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
