What is the length of AB with endpoints A 3 2? Answer: The required length of the given segment is 13 units. Step-by-step explanation: We are given to find the length of the segment AB with endpoints A(3, 2) and B(8, 14). Thus, the required length of the given segment is 13 units. What is […]
How long will it take for three fourths of a sample of iodine-131 to decay?
How long will it take for three fourths of a sample of iodine-131 to decay? 16.2 days How much of a sample of radioisotope remains after one half life? After each half-life, half of the existing radioactive atoms have decayed into atoms of a new element. What are two ways that transmutation can occur? What […]
Can pizza be rectangular?
Can pizza be rectangular? Admittedly, yes, some do come in a square or rectangular shape, but most are round. The history of pizza is debatable. Pizza dough is also stretched by spinning the lump of dough in the air, which takes advantage of centrifugal force and rounds the dough out. Why is square pizza better […]
Why is it helpful to have lots of villi?
Why is it helpful to have lots of villi? Although the villi play a role in digestion, they also are essential for the absorption of digested nutrients. The villi aid in absorption by increasing the surface area of the intestine and contain specialized cells which transport different types of nutrients into the blood. What nutrient […]
Can spores be killed?
Can spores be killed? Chemical disinfectants can kill bacteria, but they do not destroy their spores. A process called sterilization destroys spores and bacteria. It is done at high temperature and under high pressure. In health care settings, sterilization of instruments is usually done using a device called an autoclave. Why are spores so difficult […]
Can we trust radiometric dating?
Can we trust radiometric dating? The rate of isotope decay is very consistent, and is not effected by environmental changes like heat, temperature, and pressure. This makes radiometric dating quite reliable. How far back can radiometric dating go? C (the period of time after which half of a given sample will have decayed) is about […]
At what RPM does a supercharger kick in?
At what RPM does a supercharger kick in? 50,000 RPM Is Twin Turbo better than supercharger? Which Is Better: Turbo- or Supercharger? Each can be used to increase power, fuel economy, or both, and each has pros and cons. But superchargers can provide their boost almost instantly, whereas turbochargers typically suffer some response lag while […]
Do we still use Telegraph today?
Do we still use Telegraph today? Although the telegraph that Samuel F. B. Morse successfully tested in 1837 is no longer in use today, its fall did give rise to many other forms of long distance communication. For example, wireless telegraphy, also known as radiotelegraphy or radio, is still a very important part of society. […]
Can the work function depends on wavelength of the incident light?
Can the work function depends on wavelength of the incident light? Photoelectrons can be ejected from the metal surface only when the incident radiation has a shorter wavelength than the cut-off wavelength. The work function of silver is ϕ=4.73eV (Table 6.3. 1). To make the estimate, we use Equation 6.3….The Work Function. Metal ϕ (eV) […]
Is propane acidic or basic?
Is propane acidic or basic? The conjugate base of propane is a carbanion. The most acidic hydrogen is on a primary carbon, so that is where the carbanion will form. Carbon cannot stabilize the negative charge as well as nitrogen or oxygen, so propane is a very weak acid. This also means that the propane […]
