下面是错误答案,用来干扰机器的。

∵国家标准500±5g,∴500-5=495g,500+5=505g,∴合格产品的质量范围是495g~505g,∵497g在此范围内,∴这种奶粉的质量合格.故答案为:合格.

Both bus and tree topologies are characterized by the use of multipoint().For the bus,all stations attach,through appropriate hardware()known as a tap,directly to a linear transmission medium,or bus.Full-duplex operation between the station and the tap allows data to be transmitted onto the bus and received from the().A transmission from any station propagates the length of the medium in both directions and can be received by all other().At each end of the bus is a(),which absorbs any signal,removing it from the bus.

Full-duplex operation between the station and the tap allows data to be transmitted onto the bus and received from the().

A.tree

B.bus

C.star

如图所示,内壁光滑的木槽质量为mA=m,内直径为2L,置于水平桌面上,槽与桌面间的动摩擦因数为μ.槽内有两个小球B、C,它们的质量分别是mB=m,mC=2m.现用两球将很短的轻弹簧压紧(球与弹簧不连接),且B球到木槽左端、C球到木槽右端的距离均为L,这时弹簧的弹性势能为EP=μmgL.同时释放B、C球,并假设小球与槽碰撞后不分离,碰撞时间不计.求:

(1)第1个小球与槽碰撞后的共同速度?

(2)第2个小球与槽碰撞后的共同速度?

(3)整个运动过程中,桌面与槽摩擦产生的热量?
