Is a line a vector? Vectors are not lines and they have a very different function than lines. A vector is a direction and a magnitude, that’s it. A line, of course, has direction and magnitude, but it also has LOCATION. A vector can be anywhere, but a line exists within space. Can a set […]
What is the principle of viscometer?
What is the principle of viscometer? These viscometers use the principle of ‘rotational viscometry’, i.e. their measurement of product viscosity is based upon immersing a specifically selected spindle within a sample of the product followed by measurement of the torque required to rotate the spindle at a set speed whilst immersed within the product sample […]

What material absorbs sound waves?
What material absorbs sound waves? In general, soft, pliable, or porous materials (like cloths) serve as good acoustic insulators – absorbing most sound, whereas dense, hard, impenetrable materials (such as metals) reflect most. Is styrofoam a good sound blocker? Polystyrene foams such as Styrofoam can help muffle and reduce the presence of any noises from […]
What things reduce friction?
What things reduce friction? Silicone aerosols, oils, grease and ball bearings are all used to reduce friction. Air resistance force is the force of air pushing against a moving object. Air resistance (also called drag) is a type of frictional force. Who invented Maglev? Maglev — short for magnetic levitation — trains can trace their […]
Do any animals live in Lake Natron?
Do any animals live in Lake Natron? While it may be paradise for haloarchaea, many creatures can’t survive in such alkaline waters – but animals whose bodies are adapted to such pH levels also inhabit the lake, meaning Lake Natron is far from barren. Flocks of flamingos, other birds and tilapia fish all call the […]

What reaction produces O2?
What reaction produces O2? When manganese(IV) oxide is added to hydrogen peroxide, bubbles of oxygen are given off. To make oxygen in the laboratory, hydrogen peroxide is poured into a conical flask containing some manganese(IV) oxide. The gas produced is collected in an upside-down gas jar filled with water. What is the product of 2H2 […]
