Yes, a supercritical mass of fissile material such as uranium or plutonium can accelerate until a nuclear explosion occurs. When the mass reaches a critical point, a rapid chain reaction takes place, releasing a large amount of energy in the form of heat and pressure, resulting in an explosion.

What is meant by supercritical and how does it relate to making a nuclear bomb?
A subcritical mass cannot sustain a nuclear chain reaction, it dies exponentiallyA critical mass can sustain a nuclear chain reaction, but it remains constant neither increasing nor decreasingA supercritical mass not only sustains a nuclear chain reaction but it increases exponentially until the mass explodesA nuclear fission bomb must become supercritical at some time in order to explode.
What is meant by supercritical andhow dose it relate to making a nuclear bomb?
subcritical - a mass or arrangement of fissionable or fissile material unable to sustain a neutron chain reaction. It can provide a fixed amount of neutron multiplication from a neutron source, but after removal of the neutron source the chain reaction rate drops exponentially.critical - a mass or arrangement of fissionable or fissile material capable of sustaining a constant neutron chain reaction. No increase or decrease. (Nuclear reactors operate at critical)supercritical - a mass or arrangement of fissionable or fissile material capable of not only sustaining a neutron chain reaction, but once initiated the chain reaction rate rises exponentially. (Nuclear fission bombs explode when made supercritical)A nuclear fission bomb must have 2 of these states: subcritical (so that it can't explode until desired) and supercritical (so that it explodes with an effective yield). This requires a rapid "assembly" system using conventional explosives to rearrange the fissile material from subcritical to supercritical in about 1ms. A neutron source starts the chain reaction and the explosion completes in about 1 microsecond.
How does an atomic bomb explode?
The fissile fuel is packaged in the bomb as a subcritical mass.The fusing system detects the preset firing condition.A firing pulse is sent from the fusing system to the rapid assembly system.The rapid assembly system uses explosives to repackage the fissile fuel as a supercritical mass.A neutron source fires through the supercritical mass, initiating the chain reaction.The chain reaction increases exponentially until the resulting explosion disassembles the fissile fuel back to a subcritical mass.
Can you give sentences using the word accelerate?
The car began to accelerate as the driver pressed down on the gas pedal. We need to accelerate our efforts to complete the project on time. Training can help accelerate muscle growth and improve overall fitness.
What occurs when forces acting upon a body are not balance?
When forces acting on a body are unbalanced, the body will experience acceleration in the direction of the net force. This acceleration causes the body to change its velocity, resulting in motion. The body will continue to accelerate until the forces acting upon it become balanced.

What happens to katniss in the explosion?
She loses her hearing in the ear facing the explosion, until she gets to the Capital and they fix it.

Why cant you travel boat on Jupiter?
Jupiter does not have a defined surface. currently the "surface" is considered to be the top of the visible cloud deck. Below that temperature and pressure gredually increase until the atmosphere graduall phases into a supercritical fluid, neither liquid nor gas. Below that the supercritical fluid phases into liquid metallic hydrogen. However, before you even reached the supercritical layer, any boat or ship would melt or be vaporized in the extreme heat.
Did the airship fly successfully?
It did for 28 seconds until a fatal gas explosion occured.
What is when a star shrinks in on itself until it can shrink no further and it has a massive explosion?
A Super Nova
What is a good sentence using explosion?
TOday there was an there was an explosion at work and all the staff had to leave the building until the fire service said it was OK to go inside again.

How do you get nuclear weapons atomic bombs from nuclear fission?
fission is the nuclear reaction that makes both bombs and reactors possible.if a mass of fissile material is subcritical, its neutron multiplication factor is less than 1 and any chain reaction started in it will die out with only a small release of heat and radiation.if a mass of fissile material is exactly critical, its neutron multiplication factor is exactly 1 and a chain reaction started in it will be sustained at a constant rate. this can be used as a nuclear reactor.if a mass of fissile material is supercritical, its neutron multiplication factor is greater than 1 and a chain reaction started in it will accelerate out of control until it either melts (a fizzle) or explodes (a detonation). this can be used as a bomb.to make a nuclear bomb you also need 2 other things:a rapid assembly system using chemical explosives to convert a subcritical mass to a supercritical mass fast enough to prevent a fizzle caused by either stray neutrons or spontaneous fission.a neutron source to fire neutrons into the resulting supercritical mass at the optimal time to get an explosion of the desired yield. advancing or retarding the firing of the neutron source will reduce yield from the maximum possible with a given design.
What occurs when forces acting upon a body are not balance?
When forces acting on a body are unbalanced, the body will experience acceleration in the direction of the net force. This acceleration causes the body to change its velocity, resulting in motion. The body will continue to accelerate until the forces acting upon it become balanced.
Will a man in a parachute when the air resistance is less than his weight accelerate?
Yes, until he reaches terminal velocity.
