Well, the Train will have no movement since it is not moving, so a Sports car that is going 100 mph will have Momentum.
<span>Even though the Sun has a greater mass than Earth, the Moon orbits Earth because it's closer to the Earth than to the Sun. Because of this proximity between the Earth and the Moon, the Earth has a stronger gravitational pull than the Sun does. Furthermore, the Earth's mass is 81 times that of the Moon, and so at this proximity, it is more than able to overpower what pull the Sun exerts on the Moon.</span>
Because in a compressed gas particles are closer together, so the potential energy is larger, but since potential energy is negative, then the internal energy is lower
Explanation:
The internal energy of a gas is the sum of the potential energy (PE) and the kinetic energy (KE) of the molecules of the gas:
The kinetic energy of the molecules is directly proportional to the temperature of the gas, T, and it only depends on the temperature: therefore, if we take two gases at the same temperature, then their molecules have the same kinetic energy, no matter if their volumes are different.
The potential energy of the molecules in a gas instead is the energy due to the intermolecular forces between the molecules. The closer the particles are in a gas, the stronger the intermolecular forces, the larger the value of the potential energy; however, potential energy has a negative value. This means that for a compressed gas (particles closer to each other), the potential energy is more negative, and therefore the total internal energy E of a compressed gas is less than that of a rarefied gas.

The main parts of metabolism includes the two components which are: <em>Catholicism</em>, and <em>Anabolism</em>.
By definition,
density = mass/volume
The mass is 82 g
The volume is 14 cm³
Therefore
density = (82 g)/(14 cm³) = 5.857 g/cm³
In SI units, density = 5857 kg/m³
Answer: 5.857 g/cm³
