Collisions between atoms are often elastic, but sometimes inelastic collisions occur, and the lost kinetic energy can become int

ernal energy in the atoms, exciting electrons to higher energy orbitals or even ejecting then from the atom entirely, which is called ionization (and the required energy the ionization energy).2 (a) A Cs 133 atom (mass 133 amu) has an ionization energy of 4.0 eV.3 Express this energy in joules. (b) What is the minimum speed that a O16 atom can have if it is to ionize a cesium atom at rest upon impact?

Answer:

a) E = 6.4 1019 J    b)  v = 0.69 10⁴4 m / s

Explication

a) convert E = 4.0 eV

    1 eV = 1.6 10⁻¹⁹ J

   E = 4.0 eV (1.6 10⁻¹⁹ J / 1 eV)

   E = 6.4 10⁻¹⁹ J

b) Suppose we have a frontal shock and all the kinetic energy of oxygen is transferred to Cs

    Ei = K = ½ m v²

    Ef = 6.4 10⁻¹⁹ J

    ½ m v² = 6.4 10⁻¹⁹

The oxygen mass of the periodic table is

     PA = 15,999 u

     1u = 1.660 10⁻²⁷ kg

     Pa = 15,999 1,660 10⁻²⁷ kg

     m= Pa = 26,558 10⁻²⁷ kg

Let's calculate the speed

    v2 = 2 / m 6.4 10⁻¹⁹

    v2 = 2 / 26,558 10⁻²⁷ 6.4 10⁻¹⁹ =

    v = √0.4819 10⁸

    v = 0.69 10⁴4 m / s

maw [93]
Power is equal to the rate of energy usage, or work over time (W/t). It could also be consider Fd/t, since W=Fd.

Which of the following sets of characteristics describes the image formed by a plane mirror?A. Virtual and invertedB. Real and u
tiny-mole [99]
<h2>Answer: Virtual and upright</h2><h2 />

A plane mirror is a highly polished flat surface with a very high capacity to reflect incident light.  

We can understand in a better way how this works with the figure attached:  

1. The incident rays coming from the real object reach the mirror and  

2.are reflected following the law of Reflection.  

3.The prolongation of those reflected rays converge at a point that does not coincide with the actual position of the object. At that point the virtual image of the object is formed.  

4.Then, the reflected divergent rays are captured by our eye converging on the retina.  

Now, the image is said to be virtual because it is a copy of the object that looks as if the object is behind the mirror and not in front of it or on the surface, but it is not really there. However, it can be seen when we focus it with our eyes.  

In addition, the image formed is:  

symmetrical, because apparently it is at the same distance from the mirror  

the same size as the object.  

upright, because it retains the same orientation as the object.
