Which of the following is a benefit associated with nuclear energy? A. Radiation exposure and waste leakage B. Radioisotopes used as tracers in industry C. Radiation utilized in fertilizer production D. Radiophosphorous used in dental treatment

Answers

Radioisotopes used as tracers in the industry are a benefit associated with nuclear energy, therefore the correct answer is option B.

What is a nuclear power plant?

It is a particular kind of power plant where electricity is produced using a nuclear reactor that may use nuclear fusion or nuclear fission.

When a radioactive substance undergoes a nuclear reaction, a tremendous quantity of energy is produced. This energy is used to heat the water in the nuclear reactor, creating steam that is then pumped through a turbine to create electricity.

Humanity has come a long way in finding solutions to complex issues for the benefit of human society, as we can see how challenging it is to generate electricity from a trace amount of radioactive material.

Engineering-assisted applications of science are what fuel the advancement of human civilization.

The correct answer is option B because radioisotopes used as tracers in the industry are a benefit of nuclear energy.

An incandescent light bulb produces light when electrons flow through thea. air.
b. glass.
c. filament.
d. vacuum.

Answers

Electriccurrent passes through a filament of an incandescent bulb, thereby increasingit temperature. When current flows, it contains electrons through the filamentto produce light. The answer is c. Typically, incandescent light bulb consistsof a glass enclosure that contains tungsten filament. The glass enclosure containseither a vacuum or an inert gas that serves as the filament protection fromevaporating. Incandescent light bulbs contain a stem attached at to its base toallow the electrical contacts to run through the envelope without gas or airleaks

How can you describe the image formed by a plane mirror?

Answers

Look at yourself in a plane mirror and you see your image - it is upright. The image is located on the other side of the mirror since reflected rays diverge upon reflection; when mirrors produce images on the the opposite side of the mirror, the images are said to be virtual. the distance from the object to the mirror.
