Answer:
300 N/m
Explanation:
given,
Load attached to the spring, W = 54 N
length of stretch of the spring, x = 0.15 m
spring constant= ?
Force applied on the spring is calculated by the equation
F = k x
where k is the spring constant
x is the displacement of the spring due to applied load
now,
54 = k × 0.15
hence, the spring constant is equal to 300 N/m
Answer:
The gauge pressure is
Explanation:
From the question we are told that
The height of the water contained is
The height of liquid in the cylinder is
At the bottom of the cylinder the gauge pressure is mathematically represented as
Where is the pressure of water which is mathematically represented as
Now is the density of water with a constant values of
substituting values
While is the pressure of oil which is mathematically represented as
Where is the density of oil with a constant value
substituting values
Therefore
