45 points! show work! two point charges of +30.0 μc and -9.00 μc are 20.0 cm apart, with the negative charge to the right of the positive charge. taking to the right as being the positive x-direction, what is the electric field midway between these two charges?

The passing of heat through a material while the material itself stays in place. a. radiation b. conduction c. convection

How do you tell if someone actually cares about you? and just say they do?

Rank the six combinations of electric charges on the basis of the electric force acting on q1. define forces pointing to the right as positive and forces pointing to the left as negative. rank positive forces as larger than negative forces. q1,q2,q3 = positive(+) q1 = + q2 = + q3 = - q1 = + q2= - q3= + q1= - q2= + q3= + q1= + q2= - q3= - q1,q2,q3 = negative
