What is gold leaf Electroscope list its uses? A gold leaf electroscope is the device used to detect electrical charge and, if compared to a known charge, can also detect its polarity. It shows the presence and magnitude of a charge by applying a charge to a top plate of copper connected to two pieces […]
What are the two main types of nuclear reactions?
What are the two main types of nuclear reactions? The two general kinds of nuclear reactions are nuclear decay reactions and nuclear transmutation reactions. In a nuclear decay reaction, also called radioactive decay, an unstable nucleus emits radiation and is transformed into the nucleus of one or more other elements. Does a nuclear reaction destroy […]

When light can pass through an object it is called?
When light can pass through an object it is called? The phenomena when light passes through the object (a medium) is known as refraction. Refraction is defined as the bending of light ray when it passes from one medium to another. Which material do not allow light to pass through them? Translucent objects allow light […]
Why is it important to have repeated trials in an experiment?
Why is it important to have repeated trials in an experiment? When we do experiments it’s a good idea to do multiple trials, that is, do the same experiment lots of times. When we do multiple trials of the same experiment, we can make sure that our results are consistent and not altered by random […]
