Why do we need to follow Seat Belts Use Act? Seat belts reduce serious crash-related injuries and deaths by about half, according to the National Highway Traffic Safety Administration. The simple act of wearing a seat belt is the single most effective way to reduce the risk of fatality in a crash. Why are seat […]
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 […]
What is the direction of magnetic field in a bar magnet?
What is the direction of magnetic field in a bar magnet? Magnetic field lines are defined to have the direction that a small compass points when placed at a location. (a) If small compasses are used to map the magnetic field around a bar magnet, they will point in the directions shown: away from the […]
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 […]

Does snow make sounds?
Does snow make sounds? Snow can make both ‘squeaky’ and ‘crunchy’ sounds. Snow is a mixture of ice crystals, liquid water and air, and the sound it makes when you walk on it depends on the proportions of this mixture. When you walk on snow, your boots apply pressure that can break its ice crystals. […]
Does the Fermi level depend on temperature?
Does the Fermi level depend on temperature? The experiment shows that the Fermi level decreases with increasing temperature and has almost the same temperature dependence as the energy gap. It is pinned at about 0.63 of energy gap below the conduction band. How is Fermi level calculated? You can use our Fermi level calculator to […]
When a parallel plate capacitor is being charged by a DC battery Why does a galvanometer?
When a parallel plate capacitor is being charged by a DC battery Why does a galvanometer? Answer Expert Verified During charging and discharging of the capacitor, there is a flow of charge from the battery towards the plates of the capacitor, which produces a conduction current in the circuit. Hence, the galvanometer present in the […]
Is Internet a secondary source?
Is Internet a secondary source? The Internet is currently a component of the secondary data sources, one of the possible secondary data sources. The use of the Internet as a secondary source of data means both advantages and disadvantages; the qualities of the Internet should not be overvalued, although they exist. Which is an example […]
