No it shouldn't, a hypothesis doesn't need to be correct but must have an idea for why x variable effects y variable and have good reasoning. In the conclusion you should state if it's correct or not and explain why it's correct/incorrect and what answer you've determined from data.
Answer:
9000 J
Explanation:
Potential energy at the top = 10,000 J
Final potential energy = 1000 J
use the conservation of mechanical energy
Potential energy at top + kinetic energy at top = potential energy at a point + kinetic energy at that point.
10000 + 0 = 1000 + kinetic energy
kinetic energy = 10000 - 1000
kinetic energy = 9000 J
Thus, the kinetic energy is 9000 J.
Answer:
These findings led to the formation of the modern cell theory, which has three main additions: first, that DNA is passed between cells during cell division; second, that the cells of all organisms within a similar species are mostly the same, both structurally and chemically; and finally, that energy flow occurs within.

Answer:
The heat rejected is 146J.
The work done by the engine is 54J.
The thermal efficiency is 0.27
Explanation:
The efficiency of the carnot engine, which is working between a hot source at a temperature and a cold source at a temperature , is given by:
The normal boiling point of water is 373 K. ()
The temperature of triple point of water is 273.15 K ()
