If a boat is on the ocean, what is the medium?

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,?

The energy produced as a result of this flow of electrons from atom to atom is called

Specific heat refers to the amount of heat required to change 1 gram of a substance by degree(s) celsius
