In a Torricelli barometer, a pressure of one atmosphere supports a 760 mm column of mercury. If the original tube containing the mercury is replaced with a tube having twice the diameter of the original, the height of the mercury column at one atmosphere pressure is mm. A) 760 B) 1.52 × 10³ C) 4.78 × 10³ D) 121 E) 380
