Answer:
the power that can be generated by the river is 117.6 MW
Explanation:
Given that;
Volume flow rate of river v = 240 m³/s
Height above the lake surface a h = 50 m
Amount of power can be generated from this river water after the dam is filled = ?
Now the collected water in the dam contains potential energy which is used for the power generation,
hence, total mechanical energy is due to potential energy alone.
 = m(gh)
 = m(gh)
first we determine the mass flow rate of the fluid m
m = p×v
where p is density ( 1000 kg/m³
so we substitute
m = 1000kg/m³ × 240 m³/s
m = 240000 kg/s
so we plug in our values into (  = m(gh) kJ/kg )
 = m(gh) kJ/kg )
  = 240000 × 9.8 × 50
 = 240000 × 9.8 × 50 
  = 117600000 W
 = 117600000 W
  = 117.6 MW
 = 117.6 MW
Therefore, the power that can be generated by the river is 117.6 MW
 
        
             
        
        
        
Answer:
14.8 kg
Explanation:
We are given that 




We have to find the mass of the pulley.
According to question



Moment of inertia of pulley=

Where 



Hence, the mass of the pulley=14.8 kg
 
        
             
        
        
        
Answer: C
14.75g
Explanation: 
Given that the half life time = 60.5s
Let No = initial mass = 59g
N = decayed mass 
At time t = 0, No = 59g
At time t = 60.5s,
N = No/2 = 59/2 
 = 29.5g
At time t = 121
N = 29.5/2 = 14.75g
Therefore N = 14.75g
