Thiết kế mạch điện tử sử dụng chân ngõ ra (I/O) của arduino UNO để lái relay 12VDC/500mA sao cho chân Arduino xuất ra tín hiệu 5

V thì relay đóng, ngược lại chân I/O arduino xuất tín hiệu 0V thì relay hở. Mạch lái dùng BJT

Mila [183]

Even though the object is weightless, it would need inertia, I.e, you pushing it or any form of transportation. So you would still have to push that 500kg to just keep it moving in space. Say if it were a planet with less gravitational force, it would be weightless.

The photon energies used in different types of medical x-ray imaging vary widely, depending upon the application. Single dental

Alchen [17]

1. Single dental x-rays: $5.0\cdot 10^{-11}m$

The energy of the photon is

$E=25 keV = 25,000 eV$

Using the conversion factor

$1 eV=1.6\cdot 10^{-19} J$

we can convert it into Joules:

$E=(25,000 eV)(1.6\cdot 10^{-19}J/eV)=4\cdot 10^{-15} J$

The relationship between photon energy and wavelength is

$\lambda=\frac{hc}{E}$

where

$h=6.63\cdot 10^{-34} Js$ is the Planck constant

$c=3\cdot 10^8 m/s$ is the speed of light

E is the energy

Substituting into the formula, we find

$\lambda=\frac{(6.63\cdot 10^{-34}Js)(3\cdot 10^8 m/s)}{4\cdot 10^{-15} J}=5.0\cdot 10^{-11}m$

2. Microtomography: $2.0\cdot 10^{-11} m$

The energy of these photons is 2.5 times greater, so

$E=(2.5)(4\cdot 10^{-15} J)=1\cdot 10^{-14} J$

And by applying the same formula used at point 1, we find the corresponding wavelength:

$\lambda=\frac{(6.63\cdot 10^{-34}Js)(3\cdot 10^8 m/s)}{1\cdot 10^{-14} J}=2.0\cdot 10^{-11}m$
