Answer: true
Explanation: Electrons orbit the nucleus of an atom the way that planets revolve around the Sun. The electrons are like the planets in the solar system. The sun is like the nucleus in the solar system. The answer to the question is true.
Answer:
40 grams.
Explanation:
If 20 grams of C is formed from the combination or reaction of A and B chemicals in 10 minutes, 40 grams of C is formed in 20 minutes because the time is doubled so the concentration of C chemical is also doubled. If the time is increased further, more concentration of C chemical is produced until the amount of chemicals A and B are present. If we put an enzyme in the solution, the time of the reaction can be reduced.
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).
