When a nuclide's nucleus contains more protons than neutrons, a positron is created, whereas radionuclides are utilized to emit both a positron and a neutrino.

What exactly does positron emission tomography entail?</h3>
In the field of medical diagnostics, it is simple to monitor the positron emission of radiotracers. Positron-emission tomography, also known as PET scans, is frequently used to examine the structure and function of the brain. When an isotope annihilates an electron, positrons are released, which are used in positron-emission tomography. As a result, alpha photons are released that are 180 degrees apart from one another. The devices can now identify these protons, and they can also evaluate photos. A positron emission tomography (PET) scan is an imaging procedure that can help show how your tissues and organs' metabolisms or biochemical processes work. In order to display both typical and abnormal metabolic activity, the PET scan uses a radioactive substance (tracer).

Answer:
Magnetism surrounding the wire draws the needle toward the wire.
Explanation:
Magnetism is a force which is responsible for the attraction and repulsion of objects. Magnetism is also generated around the wire in which current is flowing. This magnetism is stronger when more current flows through the wire. This magnetism is stronger than the magnetism of the poles so when the compass brought near to the electric wire, the needle moves toward the wire.
The resources that have been linked to producing carbon dioxide are coal and natural gas.
Global warming is caused by the emission of greenhouse gases. Carbon dioxide emissions are the most important cause of global warming. Carbon dioxide is created by the burning of fossil fuels, such as oil, natural gas, diesel, organic-diesel, petrol, ethanol among others. Carbon dioxide have been increasing within the last 50 years and are still increasing.
