Russian nuclear weapons have traditionally had higher yield than US nuclear weapons to compensate for the greater targeting error in their missiles.
the strong nuclear force is responsible for most of it, but the weak nuclear force contributes some in the decay of fission products.
That's because the strong nuclear force only acts at very short distances.
The electrostatic force is attractive between unlike charges, and repulsive between like charges.
A strong nuclear force is as strong as 10^38 relative strength. It is the strongest of the four basic forces of nature, but also the shortest in its reach.
Strong nuclear forces hold the nucleus together: the nucleus is actually enveloped in what can be described as a nuclear envelope.
Nuclear weapons take their energy from the Strong Nuclear force that holds the atomic nucleus together.Conventional weapons take their energy from the Electromagnetic force that holds electrons in orbitals around the atomic nucleus.The Strong force is a couple thousand times stronger than the Electromagnetic force.
the energy comes from the strong nuclear force, which is almost unbelievably powerful.
It generally has a smaller magnitude, particularly in a comparison where apples are compared to apples.
the strong nuclear force is responsible for most of it, but the weak nuclear force contributes some in the decay of fission products.
Now radium hasn't practical applications. Uranium has many applications as nuclear fuel and also in nuclear weapons and strong tank armors.
If by your weapons, you mean ours (earths) weapons, then i only believe nuclear missiles are strong enough to defend us, although it would create havoc it would still be able to defend us long enough. Bullets and tank shots are no use at all. So yes, Earths weapons are strong enough to defend an alien attack.
I suspect you mean countries with nuclear weapons. If so they are: Britain France China (PRC) USA Russia India Pakistan North Korea There is strong evidence that Israel has nuclear weapons. Google "The vela incident". There is also suspicion that Ukraine may have inherited some weapons when the USSR Black Sea fleet was marooned in Sevastopol at the breakup of the USSR. Iran is almost certainly working towards nuclear weapons, and if they get them, they will use them.
That's because the strong nuclear force only acts at very short distances.
what was the answer??
Gravitational Electromagnetic Weak Nuclear Strong Nuclear
The strongest force known is called the "strong force" or "strong nuclear force".
Nuclear power is considered to be incredibly strong. Many people would argue that the power from nuclear power is the strongest in the world.
