Why do we feel weightless in an elevator? we dint feel weightless when an elevator goes down, we feel light as due to the downward acceleration of elevator, the reaction force on us by elevator reduces and thus we feel lighter. Who decides how many days in a month? A lunar calendar is simply a […]
What happens when ecosystems collapse?
What happens when ecosystems collapse? When ecosystems collapse, they rapidly lose their structure and function, with dramatic changes to their size or extent, or the species that comprise them. These losses tend to homogenise and simplify the ecosystem – fewer species, fewer habitats and fewer connections between the two. Are entire ecosystems dying? Entire ecosystems […]
Are bigger steering wheels better?
Are bigger steering wheels better? Smaller wheels may be more comfortable and take up less space, but the smaller the wheel, the more steering effort required (more so on a car with no power steering). You’ll want to ensure you don’t impair your visibility with too large of a wheel. Why did steering wheels get […]
How do you tell if a sequence is a function?
How is this reaction classified CaO H2O Ca OH 2 Heat?
How is this reaction classified CaO H2O Ca OH 2 Heat? This reaction is a combination reaction as calcium oxide, and water combines to form a single product that is calcium hydroxide. This is an exothermic chemical reaction and gives off heat. What type of reaction is HF CA OH 2 -> H2O CaF2? This […]
Do birds get shocked on electric fences?
Do birds get shocked on electric fences? The copper in electrical wires is a great conductor. Birds are not good conductors. That’s one reason they don’t get shocked when they sit on electrical wires. The energy bypasses the birds and keeps flowing along the wire instead. Why do birds sit on high wires? Why Birds […]
What happens when you stand on a scale in an elevator?
What happens when you stand on a scale in an elevator? If you stand on a scale in an elevator accelerating upward, you feel heavier because the elevator’s floor presses harder on your feet, and the scale will show a higher reading than when the elevator is at rest. What happens to your weight on […]

What happens when a rod of zinc metal is?
What happens when a rod of zinc metal is? Answer. when a rod of zinc metal is dipped into a solution of copper sulphate then the zinc reacts with it and displaces the copper. its colour will change from Blue to colourless in the meanwhile copper sulphate is blue and Zinc is colourless. What happen […]
What does it mean if electrons are shared equally evenly between the atoms?
What does it mean if electrons are shared equally evenly between the atoms? A Nonpolar Covalent Bond is created when atoms share their electrons equally. This usually occurs when two atoms have similar or the same electron affinity. The closer the values of their electron affinity, the stronger the attraction. This occurs in gas molecules; […]
