a body weight 110 gm . in air and 100 gm . in water of density 1gm/cm^3 . the density of the body in gm/cm^3 is
Answers
According to Archimedes’ principle,
“The volume of the water replaced will be equal to the volume of the body and the weight of the water replaced will be equal to the weight loss of the body in water.”
Now,
The body loses its weight
=110–100 gm
=10 gm
therefore, the weight of the water replaced = 10 gm.
The density of water is given as 1 gm/cc
so, the volume of the water replaced will be =10*1 cc = 10 cc.
Therefore, the volume of the body = 10 cc.
Therefore, Density of the body,
=mass/volume
=110/10
=11 gm/cc.
Answer:
11 gm/cm^3
Explanation:
By Archimedes’ principle,
Body weight in different mediums
weight in air = 110 gm
weight in water = 100 gm
now,
water replaced by the body = 110 -100 = 10 gm
The density of water is given 1 gm/cm^3
volume of the body = volume of the water replaced by the body = 10 cm^3
Density = mass/volume
Density of body = 110/10 gm/cm^3
Density of body = 11 gm/cm^3 ans.
