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

SpyIntel [72]

Answer:

options A and C

Explanation:

Since, the spheres are of same size and rotational speed of the sphere are not dependent on their masses. So, both the sphere will reach the bottom of the at the same time with the same speed. But their kinetic energies are different.

So, options A and C are correct.

La altura de un tornillo de banco respecto a la superficie es de 80 cm expresar dicha medida en pies..
Andrej [43]

Answer:

this measurement if feet is: 2.624672 ft

Explanation:

Notice that 80 cm can be expressed as 0.8 meters, and In order to convert from meters to feet, one needs to multiply the meter measurement times 3.28084. Therefore:

0.80 m can be written in feet as: 0.80 * 3.28084 feet = 2.624672 feet
