Answer:
C) The amount of water released through the dam and the dam's height account for the potential energy
Explanation:
The gravitational potential energy of an object is given by:
where
m is the mass of the object
g is the acceleration of gravity
h is the height of the object relative to the ground
As we see from the equation, the potential energy depends on two factors related to the object:
- its mass
- its height above the ground
So for the water in the dam, its potential energy depends on
- the mass of the water (= the amount of water released)
- the height of the water (= the dam's height)
So the correct answer is
C) The amount of water released through the dam and the dam's height account for the potential energy
As one distance is including twice, we can use the formula,
S = 2s1s2 / s1+s2
S = 2*3*5 / 3+5
S = 30 / 8
S= 3.75 m/s
So, your final answer is 3.75 m/s

Answer Explanation :
Poiseuille equation: this equation is used for non ideal flow this is used for the calculation of pressure in laminar flow it is physical law we know that fluid in laminar flow, flows across the pipe whose diameter is larger than the length of pipe
in mathematical form the equation can be expressed as
Q =
where η is the cofficient of viscosity
now if we assume a small sphere of radius a is suspended freely in the plane of the laminar flow then for assuring that the sphere does not migrate with the flow we have to calculate the rate of flow of the liquid
