Answer:
1/9
Explanation:
Sorry, I don't know if this is right, but here is what I did. We are ignoring potential energy because we assume that the student is walking and biking on level ground. Power = W/T, W = Mechanical Energy, or just Kinetic for this case. So 
, and 
. Ew = 
, and Eb =
. Put Ew over Eb. the 1/2's cancel, the m's cancel, and you are left with 
. Finally, this simplifies after cutting out the vw^2's to 1/9.
It is -59 i think or just ask someone esle for help
Answer: it is called a open circuit
Explanation:
Chain reactions
Neutrons released in a fission reaction can strike other nuclei and cause chain reactions
Explanation:
In nuclear fission reactions, the heavier atoms split into into lighter atoms, releasing neutrons at high velocity in the process. The neutrons hit other heavier atoms in the vicinity and split them too releasing more neutrons. This continuation is called chain reaction. The more the released neutrons the higher the rate of chain reactions. This causes too much energy to be produced at a go until an enormous explosion occurs (like in bombs).
In controlled nuclear fission such as in nuclear reactors, the number of neutrons is controlled so as to prevent the reactor from exploding. A wall that absorbs excess neutrons is used to control the number of chain reactions to prevent the release of too much energy at once.

Answer:
Quantum mechanics was one of the two great revolutions in modern physics. The first, or Einstein's relativity, was in fact the pinnacle of classical physics. But quantum mechanics and related theories completely changed the world of science and philosophy, and it was the end of classical physics.
Like Einstein relativity, we all use quantum mechanics on a daily basis, but its mathematical principles are very complex and beyond the reach of ordinary people without a degree in physics or mathematics.
In this post, I have tried to make this theory more accessible to all interested loved ones by stating the quantum theory and its consequences for the public.
