How does quantum theory explain blackbody radiators?
A. As the radiator is heated, it can have only certain specific
temperature values.
B. As heat is added, the radiator emits photons across a wide range
of visible-light frequencies.
O C. Raising the temperature of the radiator causes more photons of a
few possible energies to be emitted.
D. Raising the temperature results in the radiator giving off photons
of high-energy ultraviolet light.

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,?
