C. alpha = nucleus of a helium atom
beta = electron
gamma = photon
Answer:
The main difference is their energy level, 2s orbital is higher than 1s orbital.
Answer:
built a special cavity where the electromagnetic quantum states resonate with the natural vibrations of the atoms. In doing so, one cancouple a photon-based oscillator to a mechanical oscillator, controlling the mechanical quantum states with visible light. The result is a prototype of a quantum transducer, a device that converts light energy into mechanical energy (sound energy)
Explanation:
Sound energy is created by vibrating particles of medium that propagates as a wave. So in order to convert light (electromagnetic wave) to sound wave it has to be converted into electric or magnetic signals. Then these signals can be converted into sound waves.
However, if you consider the particle nature of light. It contains momentum and after collision sets the other particles into oscillatory motion but the wavelength of these vibrations is too high to be considered as sound waves.
Explanation:
It is known that equation for ideal gas is as follows.
PV = nRT
The given data is as follows.
Pressure, P = 1500 psia, Temperature, T =
= 104 + 460 = 564 R
Volume, V = 2.4 cubic ft, R = 10.73 ![psia ft^{3}/lb mol R](https://tex.z-dn.net/?f=psia%20ft%5E%7B3%7D%2Flb%20mol%20R)
Also, we know that number of moles is equal to mass divided by molar mass of the gas.
n = ![\frac{mass}{\text{molar mass}}](https://tex.z-dn.net/?f=%5Cfrac%7Bmass%7D%7B%5Ctext%7Bmolar%20mass%7D%7D)
m = ![n \times W](https://tex.z-dn.net/?f=n%20%5Ctimes%20W)
=
= 9.54 lb
Hence, molecular weight of the gas is 9.54 lb.
- We will calculate the density as follows.
d = ![\frac{PM}{RT}](https://tex.z-dn.net/?f=%5Cfrac%7BPM%7D%7BRT%7D)
=
= 3.975 ![lb/ft^{3}](https://tex.z-dn.net/?f=lb%2Fft%5E%7B3%7D)
- Now, calculate the specific gravity of the gas as follows.
Specific gravity relative to air =
= ![\frac{3.975 lb/ft^{3}}{0.0765 lb/ft^{3}}](https://tex.z-dn.net/?f=%5Cfrac%7B3.975%20lb%2Fft%5E%7B3%7D%7D%7B0.0765%20lb%2Fft%5E%7B3%7D%7D)
= 51.96
