A faulty Celsius thermometer reads -4 ℃ when placed in melting ice and 98 ℃ when placed in contact with steam at normal pressure. What is the correct temperature on Celsius scale when

this thermometer reads 32°? (Ans: 35.3 ℃)

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,?
