The Super Bowl is the annual championship game of the National Football League (NFL), the highest level of professional American football in the United States, becoming a season that begins in the late summer of the previous calendar year. The Super Bowl uses Roman numerals to identify each game, rather than the year in which it is held, with Super Bowl I being the 1966 season championship game, when the Green Bay Packers beat the Kansas City Chiefs. Super Bowl XLVI (46) was played at Lucas Oil Stadium in Indianapolis, on February 5, 2012, to determine the champion of the 2011 season; the New York Giants beat the New England Patriots.

The game was created as part of a merger agreement between the NFL and its rival league, the American Football League (AFL). It was agreed that the two leagues’ champion teams would play in an AFL--NFL World Championship Game until the merger was to officially begin in 1970. After the merger, each league was appointed as a “conference”, and the game was then played between the conference champions. Currently, the National Football Conference (NFC) leads the series with 25 wins to 21 wins for the American Football Conference (AFC).

The day on which the Super Bowl is played, now considered to be an existing American national holiday, is called “Super Bowl Sunday”, though it is not determined by the government. It is the second—largest day for U.S. food consumption, after Thanksgiving Day. In addition, the Super Bowl has frequently been the most watched American television broadcast of the year.

Because of its high viewership, commercial airtime during the Super Bowl broadcast is the most expensive of the year. Due to the high cost of investing in advertising on the Super Bowl, companies regularly develop their most expensive advertisements for this broadcast. As a result, watching and discussing the broadcast’s commercials has become a significant aspect of the event. In addition, many popular singers and musicians have performed during the event’s pre-game and halftime ceremonies because of the exposure’s attracting more fans.

如图甲所示，空间存在一范围足够大的垂直于xOy平面向外的匀强磁场，磁感应强度大小为B，让质量为m、电量为q（q>0）的粒子从坐标原点O沿xOy平面以不同的初速度大小和方向入射到该磁场中。不计粒子重力和粒子间的影响。

(1)若粒子以初速度v₁沿y轴正向入射，恰好能经过x轴上的A(a，0)点，求v₁的大小；

(2)已知某一粒子的初速度大小为v（v>v₁），为使该粒子仍能经过A(a，0)点，其入射角θ（粒子初速度与x轴正向的夹角）有几个，并求出对应的sinθ值；

(3)如图乙所示，若在此空间再加入沿y轴正向、大小为E的匀强电场，一粒子从O点以初速v₀沿y轴正向发射。研究表明：该粒子将在xOy平面内做周期性运动，且在任一时刻，粒子速度的x分量v_x与其所在位置的y坐标成正比，比例系数与场强大小E无关。求该粒子运动过程中的最大速度值v_m？

人耳对( )的感觉最灵敏，对( )的感觉次之。

A．强度；频率

B．频率；强度

C．间断音；连续音

D．连续音；间断音
