Emitting a positron (e+) means the atomic number of product nuclei decreased by one, with the same mass number.
Atomic number 20 is of Calcium, so .
So, 44Ca₂₂
<h3>What is nuclear decay?</h3>
The process through which an unstable atomic nucleus loses energy through radiation is known as radioactive decay, also known as nuclear decay, radioactivity, radioactive disintegration, or nuclear disintegration. A substance that has unstable nuclei is regarded as radioactive. Alpha decay, beta decay, and gamma decay are three of the most frequent kinds of decay, and they all entail the emission of one or more particles. Beta decay is governed by the weak force, whereas the nuclear force and electromagnetism are in charge of the other two. Electron capture is a fourth type of common decay in which an unstable nucleus seizes an inner electron from one of the electron shells.
Discrete X-rays are released from the transitions as a result of the loss of that electron from the shell, which causes a cascade of other electrons to fall into the lower shell. Iodine-125, which is frequently utilized in medical contexts, is an example.

Answer:
Mode of transportation and source of energy
Energy sources are used in several major ways
Gasoline is used in cars, motorcycles, light trucks, and boats. Aviation gasoline is used in many types of airplanes. Distillate fuels are used mainly by trucks, buses, and trains and in boats and ships. Jet fuel is used in jet airplanes and some types of helicopters.
Explanation:
Temperature is a measure of the average kinetic energy of the particles in a substance. It is the kinetic energy of a typical particle. Temperature is a measure of the average kinetic energy of the particles. in a substance.
Answer:
Triiodide preparation:
3I2 + 4NH4OH → NI3+ 3NH4I + 4H2O
Pentaiodide preparation:
AS4 + 10I2 → 4ASI5
Explanation:
Nitrogen triiodide is an inorganic compound with formula NI3. It is an extremely sensitive explosive. The reaction obtained from iodine and ammonia is:
3I2 + 4NH4OH → NI3 + 3NH4I + 4H2O
Polyiodides can be manufactured by adding stoichiometric amounts of I2 to solutions containing I- and I3-, it requires the presence of cations to stabilize them. For example, in the preparation of pentaiodoarsorane from arsenic tetramer with iodine.
AS4 + 10I2 → 4ASI5
There needs to be an origin.
The body must experience a force, for which it must have mass and an acceleration this force must be greater than any friction acting on body to avoid static friction.
The body can move towards any point outside the origin but if it returns and stops at origin, there is no displacement. It should not do that. If the body has mass, it must be made of matter.
According to Newton's third law of motion, a force needs to be exerted on the body to move it.
