Does snow absorb radar? What’s harder to detect than light rain? Light snow. That’s because snow doesn’t reflect radar beams as strongly as rain. Why do clouds not show up on radar? In addition, precipitation particles are big enough to reflect microwaves, whereas cloud particles aren’t. Hence, weather radars can detect precipitation but can’t see […]
Does oxygen and hydrogen make water?
Does oxygen and hydrogen make water? H-2-Oh no! Just mixing hydrogen and oxygen together doesn’t make water – to join them together you need energy. The trouble with adding energy into the equation is that a large-scale chemical reaction of flammable hydrogen and oxygen (which is what keeps a fire burning) is likely to result […]
What happens to kinetic energy when momentum is doubled?
What happens to kinetic energy when momentum is doubled? Kinetic energy is directly proportional to the squared of the velocity. This means that when momentum is doubled, mass remaining constant, velocity is doubled, as a result now kinetic energy becomes four times greater than the original value. Are momentum and kinetic energy the same? They […]
Can the Great Wall of China be seen from space?
Can the Great Wall of China be seen from space? The Great Wall of China, frequently billed as the only man-made object visible from space, generally isn’t, at least to the unaided eye in low Earth orbit. It certainly isn’t visible from the Moon. You can, though, see a lot of other results of human […]

Why can a magnet attract an Unmagnetized nail?
Why can a magnet attract an Unmagnetized nail? Stroking material containing iron with a magnet, placing a piece of iron in the strong magnetic field, placing a piece of iron near a strong electromagnet. The reason a magnet can attract an unmagnetized nails is that? nails become temporarily magnetized in a magnetic field. Why can’t […]
Which particle is not affected by a magnetic field?
Which particle is not affected by a magnetic field? gamma radiation When a soap bubble is given? When charge is given to a soap bubble (whether positive or negative), these charges exerience repuisive forces due to the other charges. Hence they tend to move out. Hence the size of bubble increases. What is the effect […]
Why do electrons move freely in metals?
Why do electrons move freely in metals? The valence electrons of metals move freely in this way because metals have relatively low electronegativity, or attraction to electrons. The positive metal ions form a lattice-like structure held together by all the metallic bonds. When nonmetals bond together, the atoms share valence electrons and do not become […]
