First off, nuclear criticality refers to a fission chain reaction, such as in a nuclear power reactor. The fission of a nuclear bomb, in contrast, usually involves a level of super-criticality, because more neutrons are being produced than when the reaction was started. Power plants' reactors contain less-enriched fuel (3% concentration of fissile uranium) than a bomb (99% conc.) since they're only trying to heat up water to 550 degrees for steam-- not to burn up a city. However, when we started harnessing the atom for electricity, trying to get the concentration of fuel just right proved to be tricky. You've heard of critical mass? This is an amount of a particular form of uranium that is needed for criticality to occur. Once when some uranium fuel was being mixed up, it stopped stirring; imagine if you add sugar to iced tea, stir it, then look to see the undissolved sugar swirling in the bottom of the glass-- when the fuel stopped being stirred, the uranium fell out like sugar, gathered at the bottom, and the mixture "went critical" unexpectedly (Flash / Woof). This was a criticality accident, and workers in the immediate vicinity were real unlucky. This was a tough lesson, and they changed methods so that this accident won't be repeated. Interesting stuff-- for more nuke info, research Oak Ridgeor NRC's website.
I"m not aware of this designation. Ultrasonics does not use atomic or Nuclear radiations, in fact it avoids this very real hazard. Hence it can be used on pregnant women to view the contents of the womb. Obviously, in a wholly different application, atomic submarines ( which are nuclear in power source) have sonar devices that are , indirectly, atomic powered but are not Nuclear appliances such as reactors. I have never heard these two energies coupled, so to speak.
The explosion of the Island of Krakatoa was heard in London, half-way round the world.
Nothing really, nuclear bombs have more blast than atomic.
The fireball was roughly 1500 feet in diameter (750 feet in radius).Blast damage was found at 10000 yards (30000 feet) to some of the bunkers.The blast was heard hundreds of miles away.
*three legged crow that is all that i heard when i researched it. I know some animals have three legs because of an accident or injury but a three legged crow is the only wild animal that naturally has three legs. *three legged crow that is all that i heard when i researched it.

Yes, the Heard island does have trees. The trees that are found in the Heard Island are called the Takamaka trees.
I hate nuclear weapons. There are only disadvantages. Ever heard of Chernobyl? Hiroshima and Nagasaki? Sellafield? Three Mile Island, a.k.a Harrisburg? Nukes suck! So many poor babies born with birth defects due to idiotic humans! Ugg! Thanks for ur Q though! :-)
There are two nouns in the sentence: 'accident' and 'morning'.
Overheard.
Last time i heard it was about 1 in every 72 people will have an accident

I heard a car accident.

I only heard of 4: Gravity, electro- magnetism, nuclear weak and nuclear strong.
It is physically impossible for cats and dogs to mate, let alone produce fertile offspring. I assume Three Mile Island refers to the nuclear power plant accident. I have never heard of any freak animals stemming from this, though mutations are possible due to reactions to radiation contaminated water, etc. By the way, there was a really moronic (like retarded) comic book (called Huckleberry Hound meets the Cat-Dog) floating around in the seventies. Seemed to have gender dysphoria or homo aspects rather like some other Hanna-Barbera cartoons (Top Cat, for example). But a Cat-Dog? Sorry. Nature no can do!
