An object rolls without slipping onto a surface where the coefficient of friction between object and surface is twice as great as that needed to prevent slipping. describe the subsequent motion. the object begins to slip, and the actual force of static friction increases. the object begins to slip, and the actual force of static friction doesn't change. the object continues to roll without slipping, and the actual force of static friction doesn't change. the object continues to roll without slipping. and the actual force of static friction increases.

Imagine that someone pushes one marble toward a motionless marble. would there still be action-reaction forces involved in the collision? how might the marbles’ motions be changed? ?

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
