How long does it take for rust to eat through metal? Steel is a metal that holds a lot of iron, and let’s say, for instance, that steel is constantly surrounded by environmental factors like water and oxygen, the steel may start to see signs of rust in as little as 4-5 days. Can you […]

What is the difference between a law and a theory explain?
What is the difference between a law and a theory explain? Generally, laws describe what will happen in a given situation as demonstrable by a mathematical equation, whereas theories describe how the phenomenon happens. What do hypothesis and theory have in common? In science, a theory is a tested, well-substantiated, unifying explanation for a set […]
What does refractive index indicate?
What does refractive index indicate? Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another. Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or […]
Is a capacitor a high pass filter?
What is gamma decay stopped by?
What is gamma decay stopped by? Gamma radiation is the most penetrating. It can penetrate air, paper or thin metal. It may only be stopped by many centimetres of lead or many metres of concrete. What is the strongest ionizing radiation? Alpha particles What is the most dangerous type of ionizing radiation? Gamma rays are […]
How many galaxies have we named?
How many galaxies have we named? All in all, Hubble reveals an estimated 100 billion galaxies in the universe or so, but this number is likely to increase to about 200 billion as telescope technology in space improves, Livio told Space.com. What are the 4 types of galaxies? In 1936, Hubble debuted a way to […]
Is wavelength directly proportional to frequency?
Is wavelength directly proportional to frequency? Wavelength is commonly designated by the Greek letter lambda (λ). Assuming a sinusoidal wave moving at a fixed wave speed, wavelength is inversely proportional to frequency of the wave: waves with higher frequencies have shorter wavelengths, and lower frequencies have longer wavelengths. Which Colour Has Highest intensity? violet What […]
What is biodiversity Why is it important for human life?
What is biodiversity Why is it important for human life? Biodiversity is important to humans for ecological life support, biodiversity gives a functioning ecosystem that provides oxygen, clear air and water, plant pollutions, pest control, wastewater treatment and lots of ecosystem services. How does biodiversity loss affect humans? More… 2.1 Biodiversity loss has negative effects […]
Which atom will never form a double bond?
Which atom will never form a double bond? The double bond rule states that chemical elements with a principal quantum number greater than 2 for their valence electrons (period 3 elements and lower) tend not to form multiple bonds (e.g. double bonds and triple bonds) with themselves or with other elements. Can carbon form a […]
