What element has 2 protons 2 neutrons? Helium What did Chadwick prove? In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge. For this epoch-making discovery he was awarded the Hughes Medal of the Royal Society in 1932, […]
What are the two main functions of cell wall?
What are the two main functions of cell wall? The main function of the cell wall is to provide structural strength and support, and also provide a semi-permeable surface for molecules to pass in and out of the cell. Where are cell walls found?

Why light shines off of a mirror?
Why light shines off of a mirror? A mirror is a surface that reflects light more perfectly than ordinary objects. Most objects reflect light at varying angles. This is more accurately called refraction, because the rays of light bend when they hit the object and move off in varying directions. This allows us to see […]
Which is the fastest ADC?
Which is the fastest ADC? flash ADC Why do we convert analog signals to digital? An analog to digital converter (ADC), converts any analog signal into quantifiable data, which makes it easier to process and store, as well as more accurate and reliable by minimizing errors. How is ADC value calculated? ADC has a resolution […]
