Answer:
1010713.18851 Pa
387999.259089 N
Explanation:
= Atmospheric pressure =
r = Radius = 2 m
h = Depth = 10 m
= Density of liquid methane =
g = Acceleration due to gravity = 7.44 m/s²
A = Area
Force is given by
The force exerted is 1010713.18851 Pa
The weight of the column of methane is 387999.259089 N
The pressure at a depth is given by
The pressure at the depth is
Freezing since the molecules are coming closer togther
Here we will say that there is no external torque on the system so we will have
here we know that
where we know that
Also we know that
initial angular speed will be
now from above equation
now we have
so final speed will be 2.41 rad/s
Hooke's law stated that the Force (F) exerted to compress or elongate an object to a distance (D) is proportional to that distance (D) where a certain proportionality constant, k, also known as hooke's constant is accounted for. In this case, if the displacement is tripled, the force required will also be tripled.
