Aparticle leaves the origin with a speed of 3.3 106 m/s at 34 degrees to the positive x axis. it moves in a uniform electric field directed along positive y axis. find ey such that the particle will cross the x axis at x = 1.5 cm if the particle is an electron.

Astone is thrown with a speed v0 and returns to earth, as the drawing shows. ignore friction and air resistance, and consider the initial and final locations of the stone. which one of the following correctly describes the change δpe in the gravitational potential energy and the change δke in the kinetic energy of the stone as it moves from its initial to its final location? options a.δpe = 0 j and δke = 0 j b.δpe is positive and δke is negative c.δpe = 0 j and δke is positive d.δpe is negative and δke is positive e.δpe = 0 j and δke is negative

The three classes of rocks are sedimentary, metamorphic, and igneous. how are rocks classified into one of these three groups?
