Which of these explanations is describing the action-reaction law?" If the same amount of force is applied to a baseball and a softball, the baseball will
have more acceleration because it has less mass.
Once the ball is in motion, it will remain in motion until an unbalanced force changes
the motion
When the bat hits the ball, the ball also applies a force to the bat. Sometimes this
force is large enough ti break the bat.
O None of these describe the action-reaction law

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,?
