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 […]

What is unit of Parallax? Stellar parallax measures are given in the tiny units of arcseconds, or even in thousandths of arcseconds (milliarcseconds). The distance unit parsec is defined as the length of the leg of a right triangle adjacent to the angle of one arcsecond at one vertex, where the other leg is 1 […]

What are the best oxidizing agents? The strongest oxidant in the table is F2, with a standard electrode potential of 2.87 V. This high value is consistent with the high electronegativity of fluorine and tells us that fluorine has a stronger tendency to accept electrons (it is a stronger oxidant) than any other element. Which […]

Is speed a unit? Speed can be thought of as the rate at which an object covers distance. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second, but the most common unit of speed in everyday usage is the kilometre per hour or, in the […]
