Answer:
This question is incomplete
Explanation:
This question is incomplete because of the absence of the drawing referred to in the question.
However, each option refers to a particular respiratory system and with the organs and the tissues mentioned here one can eventually identify which option is correct when the drawing is available.
A) The system described here is the cardiovascular system (or the circulatory system). This system involves the heart, blood vessels and the blood (which are what help in the transport of the materials mentioned in the question).
B) The system described here is the digestive system. This system involves the gastrointestinal tract and organs (that assist in the production/secretion or storage of chemicals that breakdown food into smaller pieces) such as the mouth, esophagus, stomach, small intestine, large intestine, rectum and the anus.
C) The system described here is the skeletal system. This system involves all the bones and joint in the body (the skeleton) which also helps in protecting organs in the body.
D) The system described here is the Endocrine system. This system involves several internal glands (such as the thyroid gland and the adrenal glands) in the body.
NOTE: Identify which organ and/or tissue is present in the diagram and use that to select the appropriate option from the description of each of the options provided above.
Answer:
²³⁸₉₃Np → Pu₉₄²³⁸ + ⁰₋₁e
Explanation:
²³⁸₉₃Np → Pu₉₄²³⁸ + ⁰₋₁e
Beta radiations:
Beta radiations are result from the beta decay in which electron is ejected. The neutron inside of the nucleus converted into the proton an thus emit the electron which is called β particle.
The mass of beta particle is smaller than the alpha particles.
They can travel in air in few meter distance.
These radiations can penetrate into the human skin.
The sheet of aluminium is used to block the beta radiation
⁴₆C → ¹⁴₇N + ⁰₋₁e
The beta radiations are emitted in this reaction. The one electron is ejected and neutron is converted into proton.
Sun, use fusion to combine hydrogen atoms into helium atoms,
B) It was transformed into 350 J of heat energy.
Explanation:
The remaining 350J of energy must have been transformed into 350J of heat energy.
A fan works by converting electrical energy into heat energy.
- According to the third law of thermodynamics "no system is 100% efficient". The conversion of the energy from one form to another involves a lost in energy.
- Heat is one very familiar way by which energy can be lost.
- Some component energy is used to heat the fan in the process and it is a wasted energy.
- Friction surfaces a heat energy in this process.
