Electricity flows from positive to positive
negative to positive
negative to negative
positive to negative

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,?

If an electric circuit is not grounded it is best to reach out and touch it to provide the ground a.true or b.false

By what factor does the drag force on a car increase as it goes from 65 to 110 km/h?
