What is the relationship between height and gravitational potential energy of water behind a dam?

Physics
1 answer:
Andrews [41]3 years ago
7 0

Answer:

3. h^2

Explanation:

Energy of volume contained in a dam is given by

E=\dfrac{1}{2}A\rho gh^2

where,

A = Horizontal surface area of the barrage

\rho = Density of water

g = Acceleration due to gravity = 9.81 m/s²

h =  Vertical tidal range,

It can be seen that

E\propto h^2

Hence, the energy is proportional to h^2

At which points would the river be traveling the slowest?
Vesnalui [34]

Answer:

This would be traveling at the lower reaches.

Explanation:

A river would be traveling the fastest at the upper reaches and it becomes slower at the middle reaches and the slowest at the lower reaches. A place where water flows fast in a river is where the width is narrow and the bottom is steep. (This is just examples incase you would like to keep notes).
