Muaj pes tsawg qhov kev xeem nyob rau hauv kev sib koom ua ke?
Ua ke science cov menyuam kawm ntawv yuav zaum rau kev xeem thaum kawg ntawm chav kawm raws li qhia ntawm no. Yuav muaj ob Biology xeem , ob Chemistry kev xeem thiab ob Physics kev xeem.
Ntev npaum li cas yog kev xeem science ua ke?
Cov tub ntxhais kawm yuav zaum 2 kev xeem hauv ib qho kev kawm ( Biology , Chemistry & Physics). Txhua kev xeem yuav yog 1h 15 feeb ntev thiab tsim nyog 70 qhab nia. Txhua kev xeem yog tsim nyog 16.6% ntawm tag nrho Ua ke Science GCSE.

ob Ntawm no, cov ntsiab lus twg yog kev zam rau Aufbau txoj cai? Piv txwv li, ruthenium, rhodium, nyiaj thiab platinum yog tag nrho kev zam rau Aufbau txoj cai vim yog sau los yog ib nrab puv subshells. Ib sab saum toj no, yog vim li cas electron configuration rau tooj liab 1s22s22p63s23p63d104s1 es tsis txhob 1s22s22p63s23p63d94s2?
Yuav ua li cas koj sau txoj kab nqes nqes intercept daim ntawv nyob rau hauv tus qauv daim ntawv?
Standard form yog lwm txoj hauv kev los sau daim ntawv nqes hav-intercept (as opposed to y=mx+b). Nws sau li Ax+By=C. Koj tuaj yeem hloov daim ntawv nqes hav-intercept rau cov qauv zoo li no: Y=-3/2x + 3. Tom ntej no, koj cais qhov y-intercept (qhov no nws yog 2) zoo li no: Ntxiv 3/2x rau txhua sab ntawm kab zauv kom tau qhov no: 3/2x + y = 3
