Julie walked to her friend's house to spend the afternoon. she walked at 4 mph. when she went home, she ran at 6 mph so she wouldn't be late. what is true about her average speed and average velocity? aher average speed is smaller than her average velocity bher average speed and her average velocity are the samecher average speed is 0, but her velocity is notdher average speed is grater than her average velocity

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
