Answer:
8.00 kJ
Explanation:
The first thing is to determine what quantities are there.
the mass of water = 1 000 kg
initial velocity, u = 6 m/s
final velocity, v = 4 m/s
the generator is operating at 100 % efficiency, so there is no energy loss.
The kinetic energy, Ek is converted to electrical energy, therefore Ek = electrical energy.
The kinetic energy is calculated as follows:
Ek = 1/2 mv²
= 1/2×(1 000)× (4)²
= 8 000 J/s
= 8.00 kJ Ans

Answer:
61.0168 g/mol Explanation:
I believe it’s C, by the air movement
Q=mc(Tf-Ti)
= (9Kg)(1.68 KJ/KgC)(97-12)
= 1285.2 KJ
~ 1300 KJ
