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 should I check in my car every morning?
What should I check in my car every morning? The fluid levels of your car should be checked routinely every morning. These are your car’s engine oil, automatic transmission fluids, radiator coolant reservoirs, power steering, windscreen washer, battery, brake, and clutch fluid. What should every driver do before leaving on a trip? 10 things you […]
Which is a better absorber of heat white or black?
Which is a better absorber of heat white or black? The amount of energy absorbed and radiated is decided by the colour. White is a good reflector while black is a good absorber of heat. Among other colours there is a gradation of temperature. The only difference between them is the colour with which they […]

What are 4 types of echinoderms? Classes of Echinoderms. The phylum echinoderms is divided into five extant classes: Asteroidea (sea stars), Ophiuroidea […]
How long does it take to drive 120 miles at 60 mph?
What is the danger zone for food in degrees?
What is the danger zone for food in degrees? The danger zone is the temperature range in which food-borne bacteria can grow. Food safety agencies, such as the United States’ Food Safety and Inspection Service (FSiIS), define the danger zone as roughly 40 to 140 °F (4 to 60 °C). What kind of salt do […]
Why does binding energy decrease?
Why does binding energy decrease? The above figure illustrates that as the atomic mass number increases, the binding energy per nucleon decreases for A > 60. As the repulsive forces are increasing, less energy must be supplied, on the average, to remove a nucleon from the nucleus. In other words, the BE/A has decreased. What […]
What is relation between alpha and gamma?

Linear expansion – α Cubical / Volumetric expansion – γ Thus, the relation between linear expansion and cubical expansion is, γ = 3α What is the relation between I and Alpha? Derive the equation, α=i-1n-1. Derive a relation between degree of dissociation and van’t Hoff factor. At start, […]
How a renewable resource can run out and give examples?
How a renewable resource can run out and give examples? Non-renewable resources are used faster than they can be replaced. Once they’re gone, they are, for all practical purposes, gone. Renewable resources are so abundant or are replaced so rapidly that, for all practical purposes, they can’t run out. Renewable resources include solar, wind, hydro, […]
What are the best oxidizing agents?
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 […]
