Explanation:
Work done by gravity is given by the formula,
W = ......... (1)
It is known that when levels are same then height of the liquid is as follows.
h = ......... (2)
Putting value of equation (2) in equation (1) the overall formula will be as follows.
W =
=
= 0.689 J
Thus, we can conclude that the work done by the gravitational force in equalizing the levels when the two vessels are connected is 0.689 J.
Answer:
Explanation:
m = Mass attached to spring = 14 kg
g = Acceleration due to gravity =
x = Displacement of spring =
k = Spring constant
The force balance of the system is given by
The spring constant for that spring is .
