What is the kinetic energy of a nuclear bomb?

What is the kinetic energy of a nuclear bomb?

Thus, a 1 kiloton nuclear weapon is one which produces the same amount of energy in an explosion as does 1 kiloton (1,000 tons) of TNT. Similarly, a 1 megaton weapon would have the energy equivalent of 1 million tons of TNT. One megaton is equivalent to 4.18 x 1015 joules.

How much energy is in a nuclear bomb?

The amount of energy released by fission bombs can range from the equivalent of just under a ton to upwards of 500,000 tons (500 kilotons) of TNT (4.2 to 2.1×106 GJ). All fission reactions generate fission products, the remains of the split atomic nuclei.

What are the four types of nuclear explosions?

The main types, which will be defined below, are (1) air burst, (2) high-altitude burst, (3) underwater burst, (4) underground burst, and (5) surface burst.

What is the biggest nuclear bomb today?

With its retirement, the largest bomb currently in service in the U.S. nuclear arsenal is the B83, with a maximum yield of 1.2 megatons.

Can one nuclear bomb destroy a country?

They are considered the most destructive weapons in the world – their explosions are so powerful, just one nuclear bomb could destroy an entire city. Nukes, as nuclear weapons are known, are far more damaging than even the biggest normal, non-nuclear bombs.

What if every nuke went off at once?

If every single one of the world’s nukes went off, then, there will be a near-100 percent reduction in solar radiation reaching Earth’s surface for several years, meaning the planet would be shrouded in perpetual darkness for that time.

At what height do nukes explode?

The destructive force associated wiht a nuclear explosion vary with the location of the point of burst in relation to the surface of the earth. The main types are: High Altitude Burst. Detonation above 100,000 feet.

What would happen if we nuked the sun?

Absolutely nothing except we would be providing the Sun with more fuel. We would be providing more fuel since the Sun is a giagantic fusion reactor. Our nukes would provide hydrogen if its a fusion bomb or uranium if its a fission bomb which our Sun would consume in fraction of milliseconds.

What is the kinetic energy of an explosion?

Its momentum is therefore 80 g m / s to the right. It’s kinetic energy is ½ * 80g * (1m/s) 2 = 40 mJ. After the explosion, 40 g is moving to right at 131 m/s, and the other 40 g to the left at 129 m/s. The total momentum is (-129m/s * 40g)+ (+131m/s * 40g), which is still the same 80 g m / s as before.

What was the energy of the first nuclear bomb?

Energy of a Nuclear Explosion. The first detonated on July 16, 1945 near Alamogordo, New Mexico, had a yield of about 19 kilotons or 80 terajoules (1 TJ = 10 12 J). The two bombs that were dropped on the Japanese cities Hiroshima and Nagasaki during World War II were comparable in size: 15 and 20 kilotons or 63 and 84 terajoules, respectively.

What is the formula for momentum after an explosion?

The formula for momentum is not $p=mv$ but it is $\\vec p=m\\vec v$. This being said, after an explosion, the velocities of the fragments have increased and so is the kinetic energy of the entire system (chemical energy $\\rightarrow$ kinetic energy in the explosion) but the net momentum does not change.

What happens to kinetic energy after a firecracker explodes?

Energetically, that firecracker is very different after it explodes; internal potential energy has become kinetic energy of fragments.” It goes on to say, “Nevertheless, the centre-of-mass concept remains useful in categorizing the kinetic energy associated with a system of particles.
