33. Shown are four rods that have identical properties except for their color and are free to rotate about their center of masses. Black is perfectly absorbing, white is perfectly reflecting while gray is somewhere in between. Transparent is perfectly transmitting. Which of the following will move with the fastest angular speed, after being hit by identical laser beams (at t-0)? laser laser laser laser black rod white rod gray rod transparent rod А. Black rod B. White rod C. Gray rod D. Transparent rod E. All rods will have the same angular speed.
