What happens when a neutron hits a control rod? If the neutron hits another nucleus, the reaction continues. If the nucleus hits a control rod it is absorbed and no further reaction takes place. 9) Compare the chain reaction that occurs when the control rods are inserted further into the reactor versus when they are […]
Is chain pulling a crime?

Why do we need replicates in an experiment?
Why do we need replicates in an experiment? The replication reduces variability in experimental results. Stop of variability increases their significance and the confidence level. Finally, the researcher can draw conclusions about an experimental. Scientists must replicate experiments to ensure validity and account for error. Why is repetition of experiment important? The repetition principle is […]
Do microwaves have radiation?
Do microwaves have radiation? Microwaves are a form of “electromagnetic” radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation spans a broad spectrum from very long radio waves to very short gamma rays. But the most common consumer use of microwave energy is in microwave ovens. What […]

How gravity is created?
How gravity is created? Earth’s gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body. You exert the same gravitational force on Earth that it does on you. But because Earth is so much more massive than you, your force doesn’t really have an […]
What is the direction of acceleration of a particle in a uniform circular motion?
What is the direction of acceleration of a particle in a uniform circular motion? An object undergoing uniform circular motion is moving with a constant speed. Nonetheless, it is accelerating due to its change in direction. The direction of the acceleration is inwards. The animation at the right depicts this by means of a vector […]
Which shows the weight of an atom?
Which shows the weight of an atom? The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 […]
