Alfredo makes a diagram to organize his notes about charging objects.
which statement should he place in the region marked x?
it does not involve touching the objects together.
the objects develop opposite charges.
electrons move between objects.
the objects have the same charge.

Along the line connecting the two charges, at what distance from the charge q1 is the total electric field from the two charges zero? express your answer in terms of some or all of the variables s, q1, q2 and k =14ï€ïµ0. if your answer is difficult to enter, consider simplifying it, as it can be made relatively simple with some work.

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.

An airplane is flying with a velocity of 240 m/s at an angle of 30.0∘ with the horizontal, as the drawing shows. when the altitude of the plane is 2.4km,a flare is released from the plane. the flare hits the target on the ground. what is the angle θ?
