Answer:
ρ = 830.32 kg/m³
Explanation:
Given that
Oil head = 12.2 m
h= 12.2 m
Pressure P = 1.013 x 10⁵ Pa
Lets take density of the liquid =ρ
The pressure due to liquid P given as
P = ρ g h
Now by putting the all values in the above equation
1.013 x 10⁵ Pa = ρ x 10 x 12.2 ( take g =10 m/s²)
ρ = 830.32 kg/m³
Therefore the density of oil is 830.32 kg/m³
River shore is located at distance

speed of the woman is given as

now the time taken by the woman to cover the distance is


for the same time interval the dog will run to and fro with speed 4.5 m/s
so the total distance moved by the dog is given by



<em>so the total distance that dog will move is 7200 m or 7.2 km</em>
