Water is flowing through a horizontal pipe of non-uniform cross-section. the speed of water is 30 cm/s at a place where pressure is 10 cm (of water). calculate the speed of water at the other place where the pressure is half of that at the first place

"We can solve this question by using Bernoulli's theorem.

Which is,

Where,

P = pressure

v = velocity

h = height

g = acceleration due to gravity

Since it is a horizontal pipe, the height (potential energy part becomes zero)

Now the equation can be changed as below,

but we know that, pressure (P) = ⍴hg

substituting the given values in the above equation,

Therefore, speed of water "

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
