1.	deepak painted three closed container to prevent then from rusting . cube container of edge 30 cm,a cubical container of length 50 cm breadth 25 cm and height 45 cm and cylindrical drum of radius 10cm height 1m
Answer» Answer: Step-by-step explanation: Fraction of volume immersed before PUTTING the new weight= ρ water ρ block = 1000 800 =0.8 i.e., 20% of 3 cm or 0.6 cm is above water. LET W is the new weight, then SPRING will be compressed by 0.6 cm. ∴ W+weight of block=Upthrust on whole volume of block+spring force or W=(3×10 −2 ) 3 ×1000×10+50×(0.6×10 −2 )−(3×10 −2 ) 3 ×800×10 ∴ W=0.354 NFraction of volume immersed before putting the new weight= ρ water ρ block = 1000 800 =0.8 i.e., 20% of 3 cm or 0.6 cm is above water. Let W is the new weight, then spring will be compressed by 0.6 cm. ∴ W+weight of block=Upthrust on whole volume of block+spring force or W=(3×10 −2 ×800×10

Answer:

Step-by-step explanation:

Fraction of volume immersed before PUTTING the new weight=

water

block

1000

800

=0.8

i.e., 20% of 3 cm or 0.6 cm is above water. LET W is the new weight, then SPRING will be compressed by 0.6 cm.

∴ W+weight of block=Upthrust on whole volume of block+spring force

W=(3×10

−2

)

×1000×10+50×(0.6×10

−2

)−(3×10

−2

)

×800×10

∴ W=0.354 NFraction of volume immersed before putting the new weight=
