The freezing point ..... :)
technically usually the warmer object/substances particles move master which causes friction among the particles plus the kinetic energy being converted to thermal energy, so i would say the hand.
The bending of a wave as it crosses a boundary between 2 mediums at an angle is called refraction.
Answer:
M1 = 16.9 mA
M2 = 0 A
Explanation:
As the ratio of the two sets of series resistors is almost exactly identical, there is no voltage difference across M2 to cause current flow
269/(269 + 439) = 0.3799...
500/(500 + 815) = 0.38022
M2 = 0
M1 sees only the current flowing through the far left resistors in series
A = V/R = 12/(269 + 439) = 0.016949... ≈ 16.9 mA
