Mavzu: Turli shakldagi jismlarning zichligini aniqlash.
Maqsad:To‘g‘ri geometric shakldagi va to‘g‘ri geometrik shaklga ega bo‘lmagan jismlarning zichligini aniqlash.
Kerakli asbob va jihozlar:to‘g‘ri parallelepiped shakldagi plastmassa, yog‘och va metall brusok jismlar, elektron tarozi, chizg‘ich, menzurka, suv, ip, vint.
1 To‘g‘ri geometrik shaklga ega bo‘lgan jismlarning zichligini aniqlash. Ishni bajarish tartibi: To‘g‘ri parallelepiped shakldagi jismlarning zichligini aniqlash
1.Parallelepiped shakldagi jismlarning massalari (m)ni tarozida o‘lchang.
2.Parallelepiped asosining uzunligi a, eni bva balandligi h ni chizg‘ich yordamida o‘lchang.
Parallelepiped shakldagi jismlarning hajmlarini V=a∙b∙h formulaga ko‘ra hisoblang.
Parallelepiped shakldagi jismlarning zichligini ρ=m/V formulaga ko‘ra hisoblang va uning son qiymatini jadvalga yozing.
5.O‘lchangan va hisoblangan natijalarni jadvalga yozing.
