Answer:
Explanation:
Equation of the rocket is,
Here, v' is the relative velocity of rocket.
In space F is zero.
So,
Now the momentum can be obtained by multiply by m on both sides.
Now for maxima, 
Now,
Therefore, the mass of the rocket while having maximum momentum is 
If both nuggets have the same mass and different densities then it can be concluded that the volume with the highest density is smaller.
For, so to speak, density is a relation of how much mass is there in a given volume. So the more the mass and the smaller the volume, the greater the density.
To verify this, let us calculate the volumes of iron pyrite and gold pyrite.
For the iron pyrite nugget:
density = mass / volume
volume = mass / density
volume = 50/5
volume = 10cm3
For the gold nugget:
volume = mass / density
volume = 50 / 19.3
volume = 2.59cm3
Therefore it is found that the nugget with the highest density (gold) is the one with the lowest volume.
The relationship between electrical and charge force is that electrical force strengthens and increases the energy pulses and reflects off an object and makes the force about two times greater with charge.
