Meters per second squared:
If you think about it, acceleration is about how fast speed changes. Speed is measured in meters per second:
So if you take that and just measure it over time, you get meters per second squared.
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
Answer:
the layers of atmosphere are heated through radiation and convection.
Explanation:
- heat is transferred from sun through radiation
- and current through convection
Answer:
(d) A strong electron-phonon interaction
Explanation:
Superconductivity -
The phenomenon of superconductivity is due to the attractive force between electrons from the exchange of the phonons that cause the bound pair of electrons known as cooper pairs .
A strong electron -phonon intercation is suitable condition for superconductivity and high resistance .
Answer:
The correct option is (d).
Explanation:
- The energy a particle has because of its charge and its position relative to another particle is called thermal energy.
- It is the energy that comes from heat. This is generated by the movement of the particles in an object.
- Thermal energy is the energy an object or system has due to the movement of particles within.
Hence, the correct option is (d).
