Answer:
The answer is
<h2>2560 J</h2>Explanation:
The kinetic energy of an object given it's mass and velocity can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 80 kg
v = 8 m/s
The kinetic energy is
We have the final answer as
<h3>2560 J</h3>Hope this helps you
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.
