The answer is 3
I hope I helped
Answer:
56
Explanation: I did the test
According to KE = (3/2)kT
reducing temperature, in KELVIN, by half, average KE is reduced by half.
A - the amount of time needed to travel the distance
The formula for speed is distance/time and the unit is m/s. Therefore you divide the distance travelled by the time it took to travel it.
Answer:
The value of L is 0.3 nm.
Explanation:
Given that,
Energy 
Transmission probability = 10⁻³
We need to calculate the value of L
We know that,
Formula of tunneling probability
....(I)
Where,
....(II)
Where, m = mass of electron


Put the value in equation (II)


From equation (I)






Hence, The value of L is 0.3 nm.
