An electron with initial kinetic energy 5.1 ev encounters a square potential barrier with height 10.0 ev .what is the width of the barrier if the electron has a 0.60 % probability of tunneling through the barrier? express your answer to two significant figures and include the appropriate units.

Explanation:

E = Initial kinetic energy = 5.1 eV

= Potential barrier height = 10 eV

P = Probability =

m = Mass of electron =

Constant A is given by

K is given by

We have the relation

The width of the barrier is

question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.
