Answer:
option (E) 1,000,000 J 
Explanation:
Given:
Mass of the suspension cable, m = 1,000 kg
Distance, h = 100 m
Now, 
from the work energy theorem 
Work done by the gravity = Work done by brake 
or
mgh = Work done by brake 
where, g is the acceleration due to the gravity = 10 m/s²
or
Work done by brake  = 1000 × 10 × 100
or
Work done by brake = 1,000,000 J 
this work done is the release of heat in the brakes
Hence, the correct answer is option (E) 1,000,000 J 
 
        
             
        
        
        
Kinetic energy is energy of motion.
In the cases of a stretched rubber band, water in a reservoir, natural gas, or an object suspended above the ground, everything is just laying there, and nothing is moving. There's nothing there that has kinetic energy.
If there's any wind, then air is moving. The moving air has kinetic energy.
 
        
             
        
        
        
Answer:

Explanation:
We define our values according to the text,
R= Radius
 Velocity
Velocity 
 Strenght of the vortex filament
Strenght of the vortex filament
From this and in a vectorial way we express an elemental lenght of this filmaent as  . So,
. So,

Where  imply a vector acting perpendicular to both vectors.
 imply a vector acting perpendicular to both vectors.
Applying Biot-Savart law, we have,

Substituting the preoviusly equation obtained,



So we can express the velocity induced is,

Yes, it is true that the effects of agriculture and industry can be more harmful with the further loss of wetlands since industry usually requires large amounts of land.
