Answer:
d) 0.011%
Explanation:
The probability for tunneling the barrier is given by the following formula:
( 1 )
me: mass of the electron
Uo: energy of the barrier
E: energy of the electron
d: thickness of the barrier
By replacing the values of the parameters in (1), you obtain:
hence, the probability is 0.011% (answer d)
V=d/t
D=vt
T=d\v
Since we are solving for time, we use the third equation: t=d/v.
Distance: 605 miles
Velocity: 55 mph
T=605/55=11.
Since the velocity was in miles per HOUR, our time is in hours as well.
11 hours.
Hope this helps!

See the explanation below
Explanation:
In the attached image we can see the free body diagram and forces acting on the book.
Force F, which acts to the right, the friction force which acts in the opposite direction to the movement, i.e. to the left.
The force exerted by the weight of the book that is equal to the product of the mass of the book by the gravity of the book. The normal force that is equal in magnitude to the weight of the book but in the opposite direction.
