Question

a cylinder is filled with water to a level of 50 cm cube cylinder is marked up 200 uses with each division of them when a body is immersed in a liquid we observe the mark on the cylinder in 75 cm cube if the density of body is 250 gram centimetre cube then the mass of the body inS.I system is

Answer 1

Mass of of a cube is 50gm .

mass is quantity of matter contained in it. Density is mass per unit volume of the substance.

Volume

initial volume v1 = 20ml

Final volume V2 = 40ml

Volume of the water = v2-v1 = 40–20 = 20ml or 20 cm^3

The volume of displaced water is equal to volume of the object ( cube).

Density of the cube = Mass/ volume

=50/20

= 5/2 = 2.5 gm/ cm^3

Answer 2

Answer:6.250kg

Explanation:

Volume =v2-v1___1

V2=75

V1=50subs in 1

V=75--50=25cm3

Mass=density×volume_____2

V=25cm3

Density =250gcm3

Subs in 2

M=250×25=6250g

1kg=1000g

6250g=_____kg_???

6250÷1000=6.250kg
