Is NB 93 stable?
Is NB 93 stable? Niobium-93 atom is the stable isotope of niobium with relative atomic mass 92.906378, 100 atom percent natural abundance and nuclear spin 9/2. Who is element 41 named after? Its name comes from Greek mythology, specifically Niobe, who was the daughter of Tantalus, the namesake of tantalum. The name reflects the great […]
How do you show that two vectors are equal?
How do you show that two vectors are equal? Vector is equal to vector b. For two vectors to be equal, they must have both the magnitude and the directions equal. What does the modulus sign mean? In mathematics, the absolute value or modulus of a real number x, denoted |x|, is the non-negative value […]
What will increase fringe spacing?
What will increase fringe spacing? With a single slit the spacing increases with wavelength, though if you reduce the width of the slit enough, the number of fringes decreases and their size increases. How fringe benefits are calculated? Employers will calculate a fringe benefit rate to determine the percentage of an employee’s hourly wage relative […]
What is the general formula of respiration?
Which is loudness closely related?
Which is loudness closely related? The loudness of a given sound is closely associated with the amplitude of the sound wave. Higher amplitudes are associated with louder sounds. Loudness is measured in terms of decibels (dB), a logarithmic unit of sound intensity. How do you manipulate sound? 7 ways to manipulate recorded sounds Warping. Manipulating […]
Why is some food heated unevenly?
Why is some food heated unevenly? Why Your Food Is Heating Up Unevenly Microwaves are sending radio waves toward your food, rather than heating it from underneath it like gas ovens. And people tend to pile leftovers with the densest part in the middle, which is why the outer edges will heat up, leaving the […]
What does light do in the photoelectric effect?
What does light do in the photoelectric effect? In the photoelectric effect, light incident on the surface of a metal causes electrons to be ejected. The number of emitted electrons and their kinetic energy can be measured as a function of the intensity and frequency of the light. Which experiment proved the particle nature of […]
Why is cavitation bad for pumps?
Why is cavitation bad for pumps? Cavitation causes pump performance deterioration, mechanical damage, noise and vibration which can ultimately lead to pump failure. Vibration is a common symptom of cavitation, and many times the first sign of an issue. Vibration causes problems for many pump components, including the shaft, bearings and seals. What is cavitation […]
