What is its effect to the environment?
What is its effect to the environment? Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water. Can humans improve their environment if so how? Avoid Taking Cars or Carpool When Possible. Cars are harmful […]
Are superconductors 100% efficient?
Are superconductors 100% efficient? A superconducting material has absolutely zero electrical resistance, not just some small amount. If conductor resistance could be eliminated entirely, there would be no power losses or inefficiencies in electric power systems due to stray resistances. Electric motors could be made almost perfectly (100%) efficient. Which metal is superconductor? But at […]

What electromagnetic waves are blocked by the atmosphere?
What electromagnetic waves are blocked by the atmosphere? In contrast, our atmosphere blocks most ultraviolet light (UV) and all X-rays and gamma-rays from reaching the surface of Earth. Because of this, astronomers can only study these kinds of light using detectors mounted on weather balloons, in rockets, or in Earth-orbiting satellites. What is an artificial […]

What were two major shortcomings of Mendeleev periodic table?
What were two major shortcomings of Mendeleev periodic table? State two limitations of Mendeleev Periodic Table Elements with large differences in properties were included in the same group. No proper position could be given to the element hydrogen. The increasing order of atomic mass was not strictly followed throughout. How were the drawbacks removed in […]
What is difference between NHE and she?
What is difference between NHE and she? Technically, a SHE and NHE are different. The NHE measures the potential of a platinum electrode in a 1 N acid solution, while the SHE measures the potential of a platinum electrode in an ideal solution (current standard of zero potential at all temperatures). What does V Vs […]
Is it harder to kick a deflated football?
Is it harder to kick a deflated football? “Basically, a little bit of air removed from the ball makes it easier to kick accurately because you get more ball surface in contact with the toe,” Timothy Gay, physics professor at the University of Nebraska, told NBC News. Why does cold air make balls deflate? As […]
