Hydroelectric power relies on the transfer of energy from waves through what medium? water wind the ground nuclear reactions

Option (1)

Explanation:

Hydroelectric power can be generated by the medium of water. A dam is needed to be constructed across a river, in which the waters are hold in the reservoir, and when the waters are allowed to flow, the turbine moves and this continuous moving of the turbines at a certain speed generates electricity.

Also new technologies has been developed. In the coastal region, where the waves are active, underground tidal turbines are placed that moves when are waves are frequently active. This has been approved as a safe method as the fishes and other organisms are not hurt due to the motion of the turbines.

Thus, the it is most efficient way to transfer energy from waves in order to generate electricity.

Thus, the correct answer is option (1).

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .

(newtons first law)

conservation of momentum law states :

momentum before collision = momentum after collision

momentum p (kg-m/s)= mass * velocity

say moving car=1 000 kg, velocity = 10 m/s then p = 1 000*10= 10 000 kg-m/s

say still car = 2 000 kg, velocity = 0 m/s then p = 2 000* 0 = 0 kg-m/s

total momentum prior to collision = 10 000 + 0 = 10 000 kg-m/s

momentum after collision = 10 000 kg-m/s

mass now = 1 000 kg+2 000 kg = 3 000 kg

10 000 = 3 000 kg* velocity m/s

10 000/3 000 = velocity

3.33 m/s = velocity after collision

an impulse is a force applied over time , momentum is exclusive of external forces and a perfect collision is implied
