Why is bronze used in Bells? Bell makers still use bronze because it has desirable properties, such as hardness and sound quality. The atomic structure of a pure metal is orderly and allows electrons to flow freely through the material. In bronze, the addition of tin to copper restricts the movement of the copper atoms. […]

Why can you not fart in space? The lack of gravity in space means the air in astronauts’ stomachs doesn’t separate from ingested food, so burping could expel more than just gas. Spaceflight missions also avoid serving high-flatulence foods, like Brussels sprouts and cabbage, to avoid “flammable butt gas” that’s hazardous in pressurized cabins. What […]

What is spatial polarization? The polarization process is likely to deepen urban socio-spatial divisions in two ways: the proportions of low- and high-income neighbourhoods can increase in the poorer and better-off parts of the city, respectively. Also, the social distance between these two parts, in absolute terms, can become more extreme. Do you think globalization […]

When was E mc2 proven? 1905 Does the inertia of a body depend on its energy content? The mass of a body is a measure of its energy-content; if the energy changes by L, the mass changes in the same sepse by L/9 10%, the energy being measured in ergs, and the mass in grammes. […]

What is the difference between dysphasia and aphasia? Aphasia is the medical term for full loss of language, while dysphasia stands for partial loss of language. The word aphasia is now commonly used to describe both conditions. Can dysphasia be cured? In mild cases of dysphasia, language skills may be recovered without treatment. However, most […]

Is calcium smaller than magnesium? However, a magnesium ion has a smaller radius than a calcium ion. This means that a magnesium ion polarises a carbonate ion more than a calcium ion does. Therefore, magnesium carbonate is easier to decompose than calcium carbonate and does so at a lower temperature. Why is magnesium ion smaller […]

What are some of the examples of exceptions to the patterns of our solar system? Exceptions to the rules: The generally orderly solar system also has some notable exceptions.

The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor. Bad Gas Mileage. If you’re spending more money than usual on fuel, your vehicle […]

What is stream function and velocity potential? Introduction. The stream function, ,, is a function specially suited for dealing with two- dimensional flow while the velocity potential, f, is a function which may be. used with either two- or three-dimensional flow. What is unit for flow rate for gases? Because of this, meter flow rates […]
