Asolid 0.6350 kg ball rolls without slipping down a track toward a vertical loop of radius r=0.8950 m.

what minimum translational speed vmin must the ball have when it is a height h=1.329 m above the bottom of the loop in order to complete the loop without falling off the track?

assume that the radius of the ball itself is much smaller than the loop radius r. use g=9.810 m/s2 for the acceleration due to gravity.

In a voltaic cell, electrons flow from the (positive/negative) to the (positive/negative) terminal.

Which articulations allow for greatest range of motion?

Although longitudinal waves can travel through all media types what is the disadvantage of this type of wave transmission? a) he efficiency of he wave transmission is greatly diminished as the media becomes less dense b) the oscillation of one set of particles has a huge impact on neighboring particles c) particles become too close together as they bump into each other making it more likely to hit other particles down the line
