Answer:
496.57492 kg/m³
Explanation:
= Atmospheric pressure = 101300 Pa
= Density of water = 1000 kg/m^3
= Height of water = 21.8 cm
= Height of fluid = 30 cm
g = Acceleration due to gravity = 9.81 m/s²
= Density of the unknown fluid
Absolute pressure at the bottom
The density of the unknown fluid is 496.57492 kg/m³

Answer:
The terminal speed is 74.833 m/s
Explanation:
The drag force is equal to square of speed:
Fdrag = k*v²
According Newton`s law:
Fnet = m*a
m*g - k*v² = m*a
If terminal speed, the net force is zero.
