Answer:
The theoretical density for Niobium is 
.
Explanation:
Formula used :
where,
= density of the unit cell
Z = number of atom in unit cell
M = atomic mass
= Avogadro's number
a = edge length of unit cell
We have :
Z = 2 (BCC)
M = 92.91 g/mol ( Niobium)
Atomic radius for niobium = r = 0.143 nm
Edge length of the unit cell = a
r = 0.866 a (BCC unit cell)
On substituting all the given values , we will get the value of 'a'.
The theoretical density for Niobium is .
Answer:
Conversion of a continuous stream of sound into a series of ones and zeroes that can be interpreted by computers results in digital audio.
Explanation:
Digital audio is a portrayal of sound recorded in, or changed over into, digital structure. In digital audio, the sound flood of the audio signal is encoded as numerical examples in a persistent arrangement. In a digital audio framework, a simple electrical sign speaking to the sound is changed over with a analog-to-digital converter (ADC) into a digital sign, regularly utilizing beat code adjustment. This digital sign would then be able to be recorded, altered, adjusted, and replicated utilizing PCs, audio playback machines, and other digital apparatuses. At the point when the sound specialist wishes to tune in to the account on earphones or amplifiers (or when a shopper wishes to tune in to a digital sound record), a digital-to-analog converter (DAC) plays out the opposite procedure, changing over a digital sign go into a simple sign, which is then sent through an audio power intensifier and at last to an amplifier. Digital audio is an innovation that is utilized to record, store, control, create and repeat sound utilizing audio flags that have been encoded in digital structure. It likewise alludes to the grouping of attentive examples that are taken from a simple audio waveform. Rather than a consistent sinusoidal wave, digital audio is made out of careful focuses which speak to the sufficiency of the waveform roughly. The more examples taken, the better the portrayal, and henceforth impacts the nature of the digital audio. Most present day sight and sound gadgets can just process digital audio, and on account of mobile phones requiring simple audio input, they despite everything convert it to digital before transmission.
Technician b says that hydrogen has better specific energy than fossil fuels. so technician b is correct.
<h3>
Does hydrogen have the highest specific energy?</h3>
- Although hydrogen has the highest energy density per mass of any fuel, it has the lowest energy density per unit volume due to its low ambient temperature density, necessitating the development of new storage technologies with the potential for higher energy density.
- Hydrogen is utilized as a rocket fuel and in fuel cells to generate power on some spacecraft because it is beneficial as an energy source or fuel due to its high energy content per unit of weight.
- Since hydrogen has a significantly higher energy content than fossil fuels, less of it is required to carry out any given task.
