What can form after the supernova of a red giant?
What will form is a neutron star or a black hole. (Strictly speaking, it's a red supergiant that becomes a supernova.)
How do supernova die?
Your question does not make sense. A supernova does not die. A supernova is what happens when a supergiant or a hypergiant star becomes unstable and cannot maintain stability and explodes cutting away half of it's mass. I hope this helps you.
How does a star turns into a neutron star?
A star 8 time the mass of the Sun turns into a neutron star when it run out of fuel, become a supergiant, and undergo supernova explosion. After the explosion, a core remains. If the core is less than 3 Solar masses, it becomes a neutron star, or else it becomes a black hole.
If a portion of a DNA strand has the base sequence ACGACG what will be the base sequence of the mRNA strand transcribed?
That mRNA sequence had to come from the complement to it. Remeber that the sequence is normally read 5' to 3'. The complement that produced it would be seen in the 3' to 5' orientation (reverse) during transcription. Therefore, find the complement source by reading the sequence in reverse and making the following substitutions: a becomes t, u becomes a, g becomes c, and c becomes g. The result is the following DNA source sequence read 5' to 3': ctaagtcgcaatttttggcat.
What does hail start out as?
Hail is a type of weather phenomenon that originally starts out as water in the form of rain. Once the rain freezes and becomes hail, it can have a diameter of 0.20 inches or more.
What do stars start to become when it runs out of fuel?
in some cases it becomes a red giant then later progresses into a wight dwarf . according to the main sequence . in other cases it becomes a red supergiant then a supernova takes place leading the dying star to become either a neutron star or a black hole according to the main sequence
Convert the following DNA sequence into its RNA equivalent and then using the genetic code convert that RNA sequence into the amino acid sequence 5tacttcttcaagact-3?
DNA Sequence = 5tacttcttcaagact-3 RNA Sequence = 3'-AUGAAGAAGUUCUGA-5'You just switch 5' and 3'T becomes AA becomes UC becomes GG becomes CThere should be no Ts in an RNA sequence.
What is the step after main sequence in a stars life?
After the main sequence, a star becomes a red giant.
What order does a nebula occur and becomes a main sequence star and then a giant?
main sequence,giant then nebula
What can form after the supernova of a red giant?
What will form is a neutron star or a black hole. (Strictly speaking, it's a red supergiant that becomes a supernova.)
When the sun becomes a red giant star with a luminosity of 1000 solar units how might the physical conditions of Neptune change?
I believe the answer is B on the test.
How long is it before a massive star becomes a red supergiant?
Supermassive stars have extremely short lifespans, ranging from some 50 million years to a mere million years.
When a star is fully formed it becomes which type of star?
A Main Sequence star.
Does a red main sequence star have fusion?
A red main sequence star would be a red dwarf or a branch red giant. To be on the main sequence, you have to have hydrogen nuclear fusion.
What happens to the diameter of a circle if its area is halved?
its diameter is lower by the square root of 2 which is 1414 times smaller
When does a newly forming star have the greatest luminosity?
A rotating nebula (a cloud of gas and dust) collapses under gravity. This creates a lot of heat energy. A "protostar" forms, before nuclear fusion begins. When the core temperature is high enough, hydrogen nuclei can undergo fusion and become helium, releasing nuclear energy. So, eventually the protostar becomes a "true" star and reaches the Main Sequence on the HR diagram. The newly forming star has its greatest luminosity during the earlyprotostar stage. (The protostar has a much bigger surface area than the final star.)
What changes are happing during the life cycle of a white dwarf?
The white dwarf will cool down till it becomes a black dwarf. If it's part of a close binary with a main sequence, giant or supergiant, the white dwarf can gain mass from the other star. This can start fusion of carbon in the white dwarf. Other fusion reactions quickly follow, causing it to explode. This is known as type 1a supernova.
