An object is moving to the left. In which direction would a force need to be exerted to make this object stop?

Give one example to show that when substances are mixed,it may result in a chemical or a physical change depending on the conditions.

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
