Answer:
12.245m3
Explanation:
The electric energy is created by The potential energy substended by the specific volume of water in dam.
Electric energy is calculated as
E= Q× V
E is Energy, Q is charge and V is Voltage
Note that this energy has been given and is 60Joules
From conservation of energy it means;
M× g×h = 60
Where M is the mass of water.
g is acceleration of free fall due to gravity which is 9.8m/S2
h is the height of water flow.
From change of subject of formula for M; we have:
M = 60/ g × h
= 60/ 9.8 × 0.5
= 12.245kg
Now how much water required means the volume of water;
Note density = mass/volume
Therefore volume = mass/density
=12.245/1= 12.245m3
Note the density of water is 1kg/m3
C.) Work done = Force x displacement = 1200 x 2.5 = 3000 J. Hope this helps!
