Are stars on the main sequence hot?
Yes, stars on the main sequence are hot. They generate energy through nuclear fusion in their cores, which creates the immense heat and light that we see and feel from Earth. The temperature of a main sequence star varies depending on its size and age, with hotter stars being more massive and younger.
Why is the spectral sequence of stars not alphabetical?
The spectral sequence of stars is not alphabetical because it is based on the temperature of the star, with O-type stars being the hottest and M-type stars being the coolest. The sequence was originally arranged in this manner by Annie Jump Cannon, a pioneering astronomer, in order to classify stars based on their spectral features.
Size of main sequence star?
A main sequence star is NOT a TYPE of star but a period in a stars evolution. Therefore all stars from the hottest to the coolest are on the main sequence at some stage - with the exception of brown dwarfs which do not reach the main sequence.
What forces act on a space shuttle when it lands?
When a space shuttle lands, the main forces acting on it are gravitational force, aerodynamic drag, and the thrust from any retro rockets or thrusters being used. Additionally, the landing gear and brakes may also generate frictional forces as they slow down the shuttle.
Main sequence stars are also called stars?
A "main sequence star" is not really a type of star but a period in a stars life. When a star is in "main sequence" it is converting hydrogen into helium. It is then usually called a dwarf star. This is the longest period in a stars lifetime. Our Sun is a yellow dwarf in "main sequence".
When a rifle fires a sequence of events take place after the firing strikes the primer what is the next event in the sequence?
Primer being struck by firing pin causes fire which ignites the gunpowder which burns and produces gas which forces the projecitle down the bore of the weapon.

DNA sequence acgtt will give what mRNA base sequence?
The mRNA base sequence corresponding to the DNA sequence acgtt is ugcaa. The mRNA sequence is complementary to the DNA sequence, with thymine (T) in DNA being replaced by uracil (U) in mRNA.
A sequence consists of 11 21 1112 3112 211213 and the logic is 'you write what you see well' is this sequence false?
No. All members of the sequence are in order and all fit the requirements of being a sequence.
How does boldore evolve in Pokemon white?
