A cylindrical swimming pool has a radius 2m and depth 1.3m .it is completely filled with salt water of specific gravity 1.03.The atmospheric preassure is 1.013 x 10^5 Pa. a. calculate the density of salt water.

​

the density of the salt water is 1030 kg/m³

Explanation:

Given;

radius of the cylindrical pool, r = 2 m

depth of the pool, h = 1.3 m

specific gravity of the salt water, γ = 1.03

The atmospheric pressure, P₀ = 1.013 x 10⁵ Pa

Density of fresh water, = 1000 kg/m³

The density of the salt water is calculated as;

Therefore, the density of the salt water is 1030 kg/m³

the current is 0.6

voltage ÷ resistance = current

so 12 ÷ 20 = 0.6

multiply 2kg by latent heat of vap
