Apples of diameter 12cm are picked from a tree and cooled in a stream of cold water to reduce their metabolism so that they store longer. Consider a stream of water at 5°C and a velocity of 0.04 m/s flowing over an individual apple. If each cooling tank contains 1000 apples, and assuming the apple has an initial temperature of 25°C, how much energy (W) do you need to supply the tank to keep it cool (based on the amount of thermal energy being removed from each apple according to the initial conditions)?

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,?
