An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object's distance from another object [reference point] is changing. A place or object used for comparison to determine if something is in motion.
Answer:
- creation of mid-ocean ridges
-creation of new mountains
-formation of earthquakes
-formation of volcanoes
Convergent boundary plate tectonic involves collisions between oceanic and continental plates. The thinner and less denser oceanic plate overriden by the thicker and more denser continental plate. The oceanic plate is forced down the mantle, this event is known as subduction. The magma present in the mantle causes melting of subduction plates. The magma enters inside these plates through pores. This magma plate becomes bouyant and moves upwards. The molten magma causes volcanic eruptions along with earthquakes. If the magma solidifies in the subduction zone it creates mid ocean ridges. The mountains are formed near the continents when the magma after volcanic eruption gets cooled and solidified.
It's always a good idea to start with the definition of the thing you're trying to find.
This problem is just trying to find out whether you KNOW the definition of acceleration. You may know it, but you haven't used it yet.
Average acceleration = (change in velocity) divided by (total time).
Change in velocity = (end value) minus (start value)
Change in velocity = (20m/s) - 0
Change in velocity = 20 m/s
Time = 10 s
Average acceleration = (20m/s)/(10s)
Average acceleration = 2 m/s^2
The answer for this question would be Planetary Nebula.
Black holes are created when the star core has a mass of more than 2.5 times of the Sun. In Supernova, fo<span>r stars with mass of more than 8 times the mass of the Sun, death is signalled by a gigantic explosion: during the first second it can be as bright as a whole galaxy with hundreds of billions of stars. In Red Giants, it is </span>due to explosion of average stars like the Sun. Lastly, in Planetary Nebula, f<span>or small stars (that is less than 8 times the mass of the Sun), at the end of the Red Giant phase, the star can’t contract enough to generate the temperatures needed for further nuclear fusion.</span>
Answer:
lymph nodes
tonsils and adenoids
thymus
Explanation:
-Arteries are the blood vessels that take the blood that contains oxygen from the heart to the tissues and are part of the circulatory system.
-Lymph nodes are glands that take care of filtering the fluid that goes through the lympathic system and are also important for the functioning of the immune system.
-Capillaries are blood vessels that connect the veins and arteries and are part of the circulatory system.
-Tonsils and adenoids are located in the throat and they help protect the body from diseases and they are part of immune system and the lympathic system.
-Veins are the vessels that take the blood to the heart and they are part of the circulatory system.
-Thymus is an organ in which the T cells develop and they help protect the body against virus and bacteria and it is part of the immune and lympathic systems.
According to this, cells or organs that are considered to be part of both the immune and lymphatic systems are:
lymph nodes
tonsils and adenoids
thymus
