Explanation:
Pulsar is also called as<u> neutron stars or white dwarfs.</u> These are formed after the supernova explosion. Their mass is higher than a normal star. And the most different thing we find in pulsar is that, in a pulsar the proton and electrons combine themselves to form a neutron. That's why this is also called as neutron star. After neutron or white dwarf the star goes to the black dwarf stage.
Remember when the core of the iron becomes iron rich that time it cannot sustain further nucleo synthesis process, that's why it goes for a supernova explosion. Which results the formation of neutron star or white dwarf, followed by black dwarf or black hole.
The answer is the last one because:
- One has three sides and the other has four which doesn't makes it equal.
- One has three vertices and the other has four vertices.
- Obtuse is an angle greater than 90° but less than 180°, so it doesn't have an obtuse angle.
- Yes, it has one right angle each.
C is the best answer for this
Answer:
after
Explanation:
The rock inclusions are older than the rock that is surrounding them. In this case, we have a rock inclusion that is dated to 56 Ma. It is an inclusion in basalt. This means that the lava flow, as it was moving in that area managed to get the rock inclusion, and as the lava started to cool off, it consolidated and trapped the rock inclusion in it for time to come. This makes up for a very interesting appearance of the rocks, as there is the basis, being all from the same type of mineral, and then inside of the uniform rock mass, there is a totally different smaller piece of rock sticking out.
So, first of all let me explain the process of hydration to you.
The water causes the hardening of concrete through a process called hydration. Hydration is a chemical reaction in which the major compounds in cement form chemical bonds with water molecules and become hydrates or hydration products.
Considering this information, the answer is D.
