Is fire a plasma state? Fire is made up of many different substances, so it is not an element. For the most part, fire is a mixture of hot gases. If the flame is hot enough, the gases are ionized and become yet another state of matter: plasma. Burning a metal, such as magnesium, can […]

When a passenger jumps out of a moving train he falls down due to inertia of? This is because when the passenger is sitting inside the train his body possesses inertia of motion but when he jumps out of the moving train his lower body suddenly stops but the upper body still has the inertia […]

What causes oxidative damage to DNA? ROS are generated from normal oxygen metabolism in cells and are recognized as a list of active molecules, such as O2•−, 1O2, H2O2 and, •OH . A nucleic acid can be oxidized by ROS through a Fenton reaction. To date, around 20 oxidative lesions have been discovered in DNA. […]

Is EFI better than carburetor? Carb vs EFI The 1,100- to 1,300-cfm dual carbs are good only over a narrow range, about 1,500 rpm at most. EFI performs well over 2,000 rpm or more. On average, if optimized, both systems perform about the same as far as how fast you get down the track. However, […]

Does light travel faster in air or glass? Light waves do not need a medium in which to travel but sound waves do. Explain that unlike sound, light waves travel fastest through a vacuum and air, and slower through other materials such as glass or water. How does a black hole attract light if it […]

How can I see my house from satellite? To see a satellite view of your house: Use the search field in the top left to enter your street address. You’ll see your address in the search results. Zoom in closer to get a detailed overhead satellite view of your home. You can drag the man […]

Who gave collision coalescence theory? form high up in the cloud where temperatures are low(-40oC) given ice nuclei is present. are minute particles around which droplets accumulate to form ice crystals. Also known as WBS after first discovered by Alfred Wegener, modified by Tor Bergeron and then finally fully elaborated by Walter Findeisen. How long […]

Who gave wave theory of light? Christiaan Huygens What did Newton do with two prisms? Intrigued by the change in shape, Newton cut a variety of holes of different sizes and shapes, but no matter the shape of the original beam, the refracted light turned more oblong. Newton also placed a second prism of the […]

What is the measure of the radius of the circle? Just remember to divide the diameter by two to get the radius. If you were asked to find the radius instead of the diameter, you would simply divide 7 feet by 2 because the radius is one-half the measure of the diameter. The radius of […]

What happens when the cross product of two vectors is 0? If two vectors have the same direction or have the exact opposite direction from one another (i.e., they are not linearly independent), or if either one has zero length, then their cross product is zero. When two non-zero vectors A and B are perpendicular […]
