When a main sequence has exhausted the fuel in its core it becomes?

The next step in its life is to become a "red giant" star.


When a main-sequence star has exhausted the fuel in its core it becomes a....?

I am pretty sure it becomes a giant if I'm not mistaken.


What happens to the star as it becomes brighter and brighter?

As a star becomes brighter, it typically undergoes changes in its core reactions, often increasing the fusion of hydrogen into helium. This heightened fusion rate generates more energy and causes the star to expand, potentially transforming it into a red giant. Eventually, depending on its mass, the star may shed its outer layers, forming a planetary nebula, or it might collapse into a supernova, leading to a neutron star or black hole. Throughout this process, the star's brightness can fluctuate significantly, reflecting its evolving internal dynamics.


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


Does the northern star get brighter when traveling north?

The North Star (Polaris) does not get brighter as you travel north. It appears to be the same brightness regardless of your location on Earth. What changes is its position in the sky relative to your viewpoint as you move northward.

What happens to the temperature of the filament as the bulb becomes brighter and brighter?

As the bulb becomes brighter, more current flows through the filament, increasing its temperature. This increase in temperature causes the filament to glow more intensely, resulting in a brighter light output.


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.


When does a comet became brighter?

A comet becomes brighter as it approaches the sun. It's at that time that the heat from the sun begins to boil the ice present in the comet, and its tail becomes visible as it moves, leaving a trail behind it that scatters light, making it appear brighter.


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 happens to the filament if the bulbs becomes brighter and brighter?

The bulb gets brighter because the filament is getting hotter. If the filament's temperature gets too high it will melt at some point and fall apart. The current will stop flowing and the bulb will "blow".


What happens to the temperature of the filament as the bulb becomes brighther?

As the bulb becomes brighter, the temperature of the filament increases. This is due to the increased flow of electricity through the filament, causing it to heat up and emit more light. The relationship between brightness and temperature is direct - the brighter the bulb, the hotter the filament.


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 is the name given to the sequence to this sequence of numbers 1-123-458-1321?

The sequence 1-123-458-1321 is known as a "look-and-say" sequence. In this type of sequence, each term is derived by describing the digits of the previous term. For example, "one 1" becomes "11," and "two 1s" becomes "21." However, the specific sequence you've provided does not appear to follow this pattern directly, so it may require further context to clarify its nature.


How does plucking the string with fingers help to make a sound louder?

The sound becomes brighter when strings are plucked and only seems to be louder.


When a low mass star first runs short of hydrogen in its core it becomes brighter because?

Low mass stars become brighter after depleting hydrogen because all of the hydrogen in the core has been fused into helium. Once this happens, hydrogen fusion begins in the outer layers, which causes more heat and light generation.
