The three point charges are on the x-axis as in the figure. The (+) charged q_{1} = 15mu * C is at x = 2m and the (+) charged q_{2} = 6mu * C is at the starting point. What should be the x coordinate of q_{3} so that the resultant force acting on q_{3} is zero?

A10 kg box initially at rest is pulled 18 meters across a horizontal, frictionless surface by a 40 n force. what is the block’s final velocity over the 18 meters?

Which composition of water moves to begin a deepwater current?

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
