Question 1: "To obtain uniform circular motion, how must the net force depend on the speed of the moving object?"
My answer: The net force has to be zero so that there is no acceleration because to be uniform circular motion the object has to have constant speed.
Question 2: "If you whirl a yo-yo about your head in a horizontal circle, in what direction must a force act on the yo-yo? What exerts the force?"
The force must be exerted in the direction of your head and your hand exerts the force.
