What is radioactivity? Ionizing radiation What is a Geiger counter? How a Geiger counter works Who invented the Geiger counter? Can you make your own? Find out moreWhat is radioactivity?There are several different types of radiation, caused by different processes. Cosmic rays, for example, arriv...
What is a radioactive tracer? (Explain your answer.)Radioactivity:The substances that disintegrate by the spontaneous emission of radiations are referred to as radioactive substances. Examples include uranium, radium, polonium, thorium, actinium, etc. The isotopes of nearly all elements of an ...
Explain, what you understand by "radioactivity". Describe how a motor works. Explain the heat engine. Water can be boiled in a paper cup, Explain how? What are the steps in the recycling process of paper? What is induction? Explain in detail. ...
Using two unconnected loops of water and the heat exchanger helps to keep water contaminated with radioactivity safely contained in one place and well away from most of the equipment in the plant. The steam from the heat exchanger is piped to a turbine. As the steam blows past the turbine'...
A physicist named Atonie Bequerel was the first to discover radioactivity. Ernest Rutherford was the first to discover alpha, beta, and gamma rays. Noble gases, electrons, protons, lanthanides and actinides were also discovered by several other scientists. The periodic table began with just ...
has since been called electromagnetism. Two of the other forces of nature are the strong nuclear force and the weak nuclear force. The weak nuclear force can be seen in, among things, radioactivity. The strong nuclear force is ten billion times as strong and binds together neutrons and ...
and chug into a formula. It's something entirely different to understand a concept and why you are using it or applying it. That's what this next set of 5 questions is about. They won't ask you to calculate much (or anything), but they will test your ability to understand a process...
Megan: But we're almost out of low-background metal. Cueball: What's that?[Close-up on Megan who lifts her hand palm up.] Megan: Modern metal is contaminated by fallout from nuclear testing, and lead also has natural radioactivity that fades over time. Megan: To shield sensitive equipme...
FEMALE STUDENT: Yes, um, Professor Harrison? You were saying that the periodic table is predictive?What exactly does that mean?I mean, I understand how it organizes the elements, but … where’s the prediction? MALE PROFESSOR: OK, let's look at our periodic table again.OK - it groups ...
