Newtons first law: The ball will go at constant speed without stopping
Newtons third law: The ball will also push back at you causing you to go back as well
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.
Answer:
6.52m/s
Explanation:
Hello!
To solve this problem follow the steps below, the complete procedure is in the attached image
1. draw a complete outline of the problem involving forces and geometries
2. Find the time that elapses from when the ball is thrown until it hits the water, this is achieved using the kinematic equation for constant acceleration and zero vertical initial velocity.
3. taking into account that the ball is launched horizontally, and that there is no horizontal acceleration, the only thing we must do is find the speed by dividing the distance traveled horizontally and dividing it by time
D is the right answer for this I think
