In 1980, over San Francisco Bay, a large yo-yo was released from a crane. Suppose the yo-yo was 108 kg, and it consisted of two uniform disks of radius 40.0 cm connected by an axle of radius 4.00 cm. What was the magnitude of the acceleration of the yo-yo during (a) its fall and (b) its rise

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
