20, in the measurement the glass brick the experiment of the refractive index, some classmate put three thumb tacks, but recorded interface MN and PQ of glass brick and the MN runs parallel with PQ and please the completion light road diagram on the original diagram.If the some classmate have been already measure the P1 go to PQ to ascend go into shoot to order of be apart from for the 5 cms, P1 go to PQ noodles up lead go into shoot the method of point line of be apart from for the 5 cms, the thickness of glass brick is 4 cms, on the PQ of go into shoot point and on the MN to shoot to order to be apart from for the 8 cms, then the glass' Li the refractive index of the brick is.
21, the some classmate uses to use the plus or minus pole that Mu file in form Europe measures ideal diode more like diagram, the AN of diode then carries for
Pole.
Four, the calculation makes a diagram
22, the double sews to hold ascend a certain of be apart from it bad is 3 ×s 10-6 ms, the monochrome light irradiation double which uses the frequency as 4 ×s 1014 Hzs now sew and ask that concerns with to strengthen or concerns with to die down.There are also a few bright grains between central and bright grain and it.
23, such as the diagram, three sets of lines of some ideal transformer
The turn full circle counts its ratio as n 1:n 2:n 3=10:5:1, load electric resistance
R 2= is 110 Ωs, R 3= is 11 Ωs, primitive line turn n 1 connect to have a 220 Vs
Hand over the electric voltage of change.Then pass n 1, n 2, n 3 top of electric current
I1, I2, the I3 is how much A respectively.
24, practice enunciation, under the sistuation that the liquid isn't very transparent, in the liquid
The department places some light source and observe to a bigger and bright spot at the liquid noodles full general because of total reflection.
Such as the refractive index of diagram liquid is 2, put some light source S in the liquid noodles next 1 m deep place, is order
The level places one flat surface mirror in the liquid of the light source next 1 m deep place, the flat surface mirror is enough big,
The liquid begs the size of the area of bright spot that the liquid noodles up becomes for the air above.
(The ray which takes no account of the empress of the surface glint shine on the influence on the flat surface mirror again)
25, a the output's electric voltage of the set alternator is a 250 Vs, the output's power is a 100 KWs, lose the electric resistance of lead the line that electricity use as 8 Ωs toward the distance, make in order to transport 5% of power, the power of the power line last loss also the customer get of electric voltage at the right moment is 220 Vs.Please beg a ratio that the full circle which rises to press transformer and declines to press transformer count respectively.
26, is shown as diagram a diameter is the light that the D circular noodles light source send out, through mutually be apart from with light source L 1 enough and greatly holds the last eyelet and project light upon the right side of the eyelet is mutually apart from the same as L enough big flat surface mirror up, light source, the eyelet place holds peaceful noodles mirrors all Shu to keep place, the center of light source, the center of the eyelet peace noodles mirror three on-line in a level.The ⑴ please make a the right side noodles that the light source holds in the eyelet place diagram up the light road of the formation light spot, and compute the size of a light spot area.If ⑵'s other conditionses be constant, the flat surface mirror changes into diameter to change into the D/2 circular flat surface mirror, the right side noodles that hold in the eyelet place then up formation of the area of light spot again is how much(don't make again light road diagram)
