Question

A block of weight 5N, when immersed half of its volume, displaces 10 L of water. Find density of the block in SI unit. Given 1000 L = 1m3.

Answer 1

Answer:

hey apply formula density = Mass /volume you will get answer

Answer 2

Answer:

25.5 m^3

Explanation:

Given: weight=5N

(you know that weight=mg, where g is the acceleration due to gravity which is=9.8).

so we can say that weight=mg=5

=> m(9.8)=5   =>  mass= 5/9.8=0.51

Now,

it is given in the question that 1000L= 1m^3

therefore, 1L=1/1000 m^3

volume=20L= 1/1000 * 20 = 0.02.

density= mass/ volume= 0.51/0.02= 0.51* 1/0.02=25.5kg/m^3
