(1.00 atm) (0.1156 L) = (n) (0.08206 L atm / mol K) (273 K) I hoped that helped
Answer:
Democritus
Explanation:
He called these "uncuttable" pieces atomos. This is where the modern term atom comes from. Democritus first introduced the idea of the atom almost 2500 years ago.
Because dark line spectra result from passing white light through ionized gasses and plasmas, which is what the atmosphere of stars are made of. These frequencies are scattered by the star's atmosphere as it leaves the surface (photosphere) of the star, and don't make it to earth.
Force on the particle is defined as the application of the force field of one particle on another particle. The magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.
<h3>What is electrical force?</h3>
Force on the particle is defined as the application of the force field of one particle on another particle. It is a type of virtual force.
The given data in the problem is
q₁ is the negative charge = 6 µC=6×10⁻⁶ C
q₂ is the positive charge = 3 µC=3×10⁻⁶ C
r is the distance between the charges=0.002 m
is the electric force =?
The value of electric force will be;

Hence the magnitude and direction of the electrical force will be 4.05×10⁴N towards the north.

Answer:
The potential difference through which an electron accelerates to produce x rays is
.
Explanation:
It is given that,
Wavelength of the x -rays, 
The energy of the x- rays is given by :

The energy of an electron in terms of potential difference is given by :

So,

V is the potential difference
e is the charge on electron


V = 12431.25 volts
or

So, the potential difference through which an electron accelerates to produce x rays is
. hence, this is the required solution.
