There must be the presence of Deuterium to define stars. Deuterium fusion, commonly known as deuterium burning, is a nuclear fusion event in which a proton and a deuterium nucleus fuse to generate a helium-3 nucleus in stars and some substellar objects.
The main characteristic that distinguishes genuine stars from ordinary gas-filled balls, or brown dwarfs as they are frequently referred as, is the presence of nuclear fusion at the core. The temperatures are therefore high enough for nuclear fusion to take place, resulting in the fusion of protons to create help. Other items on the h r diagram that aren't necessarily actual stars would be things like white dwarfs and brown dwarfs. Other particles are accepted in the process, but that's kind of the general notion. Particularly for brown dwarfs, they don't actually have fusion taking place. You can plot a star as a point on the H-R diagram once you know its brightness and temperature (or color). With brighter stars positioned higher on the y-axis, plot luminosity.

Answer:
green light have high energy
Explanation:
We have given the wavelength of the red light 
Speed of the light 
The energy of the signal is given by 
The frequency of the green light is given by:
So energy 
So green light have high energy
The microgram is the greater mass. It takes 1,000 nanograms to make just one. One microgram is 999 nanograms bigger than one nanogram.

<u>RANCIDITY</u><u>:</u></h2>
=> Rancidity is a condition in which the substance with oil and fats get oxidized when they are exposed to air. A substance is said to be rancid when there is a change in smell, taste, and colour. An example of rancidity is when a chips pack is exposed to atmospheric air which results in a change in taste and odor.
Answer:
0.69s
Explanation:
10 cm = 0.1 m
Let t be the time that radial and tangential components of the linear acceleration of a point on the rim be equal in magnitude. At that time we have the angular velocity would be
And so the radial acceleration is
The tangential acceleration is always the same since angular acceleration is constant:
For these 2 quantities to be the same
