Earl is using his hands to hold a metal pan 10 centimeters above a hot burner. how can this scenario be changed to demonstrate conduction between the pan and the burner? a. increase the temperature of the burner b. use a glass pan instead of a metal pan c. use foam potholders to hold the pan d. touch the pan to the burner

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,?
