Electric current in a (circuit) is due to a (positive charge flow or just flow) produced by (sources such as batteries, solar cells, electric machines). It’s opposed by (resistance).. and I don’t understand the large and small.. but it’s a start. Hopefully I helped
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.

Alpha emission is the process results in a change in mass number. Option B is correct.
<h3>What is mass number?</h3>
The total number of protons and neutrons in an atomic nucleus is known as the mass number, often known as the atomic mass number or nucleon number.
It's about the same as the atom's atomic mass, expressed in atomic mass units.
The alpha particle is a helium nucleus with two protons and two neutrons in an alpha decay or alpha emission. The number of protons and neutrons is reduced by two as a result of this action.
The quantity of protons and neutrons is affected by gamma emission descent. Also, while electron capture has no effect on the number of neutrons, it does raise the 1 also number of protons by one.
Alpha emission is the process results in a change in mass number.
Hence option B is correct.

The big bang is a theory of our universe and many others along with making our solar system. Meanwhile, in other universes have are solar system as well that is why we see stars at night because the sun and it's rays are so bright during the day it blocks them out.
