Answer:
D. 2
Step-by-step explanation:
Common denominator is already presented which is 4.
-3/4 and 3/4 cancel each other out.
you can also convert to decimal form -3/4 + 2 3/4 is the same as:
-0.75 + 2.75 = 2.
$2.25
5 x 21 = 1.05 10 x 12 = 1.20
Nickels: 21 Dimes: 12
1.05 + 1.20 = 2.25
If I had 25 nickels, I would have 12 dimes, and a extra 5 cents.

Answer:
Generally the barrier width is
Step-by-step explanation:
From the question we are told that
The tunneling probability required is
The barrier height is
The electron energy is
Generally the wave number is mathematically represented as
Here m is the mass of the electron with the value
h is is know as h-bar and the value is
So
=>
Generally the tunneling probability is mathematically represented as
So
=>
Taking natural log of both sides
=>
=>
