Answer:
The density of the fluid is 1100 kg/m³.
Explanation:
Given that,
Height = 5.00 cm
Pressure at top =594 Pa
Pressure at bottom = 1133 Pa
We need to calculate the change in pressure
Using formula of change in pressure
Where, = Pressure at bottom
= Pressure at top
put the value into the formula
Using formula of pressure for density
Where, = density
P = pressure
h = height
Put the value in to the formula
Hence, The density of the fluid is 1100 kg/m³.
Answer:
t = 2 s
Explanation:
As we know that fish is pulled upwards with uniform maximum acceleration
then we will have
here we know that maximum possible acceleration of so that string will not break is given as
now we have
now for such acceleration we can use kinematics
t = 2 s
