2.1) The internal energy is the total amount of energy of all the molecules in a gas
2.2)
Absolute zero is the temperature at which the kinetic energy of the molecules in a
gas is 0. Or absolute zero is the temperature at which the volume of a gas is zero.
3.1)
in
The energy needed per unit mass to bring a small test mass from infinity to that point
in a gravitational field.
3.2)
The equipotential lines aren’t straight
3.3)
4.3)
Have to make sure the spheres are perfectly still and not changing distance
6.1)
The kinetic energy of fast neutrons has to be lowered so that it collides and reacts
with the nucleus and gets absorbed so that fission can happen
6.2)
2 x 10^6 x 0.37^5 = 1.4 x 10^4 eV
6.3)
The higher the nucleon number of the moderator atoms, the more kinetic energy the
neutron loses with each collision so less collisions will be needed
6.5)
Little to none greenhouse gases produced so doesn’t contribute to climate change
The fuel is really energy dense so only a small amount is needed to get same
amount of
energy as other sources.
A nuclear power station can run 24/7, doesn’t depend on other factors like sunlight or
wind.
