如图所示的电路中，两平行金属板A、B水平放置，两板间的距离d = 40cm.电源电动势E = 24V,内电阻r = 1Ω，电阻R = 15Ω.闭合开关S，待电路稳定后，将一带正电的小球从B板小孔以初速度v₀ =" 4" m/s竖直向上射入板间.若小球带电量为q = 1×10^-2 C,质量为m = 2×10^-2 kg,不考虑空气阻力.那么，滑动变阻器接入电路的阻值为多大时，小球恰能到达A板?此时，电源的输出功率是多大？(取g ="10" m/s²)

With the widespread use of the personal computer, many authorities in the field of (56) have pointed out the need for computer literacy.
Unfortunately, there is no (57) agreement as to what the term "computer literacy" means. Some feel that computer literacy means knowing how to make the computer "compute"; that is knowing how to program computers in one or more programming languages.
Others feel that knowing how to program is merely a small segment of computer literacy. These people (58) the major emphasis in schools should be on teaching how to effectively use the many software packages that are available.
Still others suggest that computer literacy education is not required. They suggest that computers are being so rapidly integrated into our society that using a computer will be as (59) as using a telephone or a video tape recorder, and that special education will not be necessary. (60) of one’s definition of computer literacy, it is recognized by most that learning to use a computer is indeed an important skill in modern society.
