How are low mass star born?
Low mass stars are created in the same way as all other stars, with one exception. They do not accumulate enough mass to create enough pressure in the core for nuclear fusion to occur. They "glow" because of the external pressure on the core but this is not enough to initiate nuclear fusion.
Which stars do not have nuclear fusion occurring in their core?
All stars "burn" by the process of nuclear fusion. When fusion has been completed, the star dies. That can occur in several different ways and the interested party could look into the topic of stellar evolution. Neutron stars, black holes and white dwarfs are examples of end stages of stellar evolution. Some stars never really reach the stage of fusion and such large objects are called brown dwarfs. If Jupiter were not a planet, it might be deemed a brown dwarf.
Will more countries acquire nukes?
of course more countries will aquire more nukes the post soviet era has led to some missing or undefended nukes which are easy to obtian,if you have enough money and with more and more coutries obtaining nuclear power it isn't much harder to enrich uranium further to weapon status and other countries a;ready have acquired nukes like Iran and north Korea and so with more developing countries becoming more industralized it is inevitable that more sountries will develop nukes in their quest for power and land
Why do Japan and New Zealand have nuclear plants and not hydro plants?
New Zealand has an abundance of large rivers and lakes that offer potential for hydroelectric development. And these, along with some geothermal power generation, mean that about 31% of energy in NZ is generated from renewable resources. In recent years, wind power is increasing its contribution to electrical generation. There is a coal-fired power station, and most other energy is consumed by transport.New Zealand has rather set its face against nuclear power of any kind (including visiting ships), because of the hazards of nuclear activity. [In similar vein, New Zealand has expressed opposition to land mines and cluster weapons in warfare.]Oddly enough, New Zealand has large reserves of thorium sands, which may be able to be used in nuclear power plants that do not have the undesirable byproducts associated with the uranium fuel cycle.The reason why most of the world's nuclear power stations use uranium as a fuel, is that it produces plutonium as a byproduct - much valued for nuclear weapons. The electricity is almost a byproduct - it is the plutonium that the military desire at almost any cost.India is the only country currently with an interest in developing thorium reactors,Japan by contrast generates only about 3% of its energy from hydro. The balance is supplied from coal, Nuclear, and petroleum. [Presumably much of this coal energy is used in the production of steel.]Japan's earliest nuclear reactors were constructed in the 70s era, and in all fairness, knowledge of tectonic plates and underwater faults were in their infancy in those days. It would be fair to say that Japan would not today site large plants on the eastern shore, close to the subduction fault lines and the tsunami dangers that result. But forty years ago, such detail was wanting.Japan is a heavily populated country, and without nuclear generated electricity, its fossil fuel bills would be grotesque.
Is there a movie called Freddy vs Jason vs leather face?
No. Freddy vs Jason was bad enough.
What is the difference between a brown dwarf and a protostar?
A protostar is a star the is developing as is on the way to starting nuclear fusion. A brown dwarf is a failed star, one that failed to gather enough mass to start fusion.
Can nuclear power be generated as needed?
If enough nuclear plants are built, yes
A powerful machine that moves nuclear particles fast enough to make larger nuclei when the particles collide is called?
particle accelerator
What comes after nuclear fusion?
Nuclear fusion is itself a difficult enough one to crack!
How is a nuclear bomb different then a nuclear accident?
An nuclear bomb is purposefully release to pulse out damage. A nuclear accident, on the other hand, is an accident when a nuclear source (usually referring to a nuclear plant) either blows up or leaks. Although it is normally weaker and less dangerous than a nuclear bomb, a big enough explosion or a serious enough nuclear meltdown can break that limit.
How are brown dwarfs different from other stars?
A brown dwarf is a "failed star" - one that never became hot enough (not enough mass) to start nuclear fusion.A brown dwarf is a "failed star" - one that never became hot enough (not enough mass) to start nuclear fusion.A brown dwarf is a "failed star" - one that never became hot enough (not enough mass) to start nuclear fusion.A brown dwarf is a "failed star" - one that never became hot enough (not enough mass) to start nuclear fusion.
Is there any chance of a nuclear explosion from a nuclear power plant?
No. There is no possibility whatsoever of a nuclear power plant having a nuclear explosion. It is not physically, or even theoretically, possible for the core to be brought into a super-prompt critical geometry and held there long enough to consume enough fuel to "go nuclear".
Can Nuclear Weapons destroy the World?
If there are just enough nuclear weapons so yes they can destroy the World.
Why doesnt Jupiter make nuclear fusion?
Jupiter is not nearly massive enough or dense enough to hit "critical mass"; essentially, there's not enough pressure at the core of the planet to start the initial nuclear reaction and its not dense enough to maintain the reaction.
At 15.6 million degrees Celsius the temperature of the Suns core is high enough for nuclear what to occur?
For nuclear fusion.
Do jovial planets contain enough mass to produce nuclear fusion?
No, none of the planets are big enough for that
What makes a Nuclear bomb transportable?
If its designed small enough and light enough to be carried in a vehicle, or by hand.
