I will save the solving and just give the answer I came up with hope this helps

Answer
The steps in order to explain how a tornado forms are;
1. An extreme difference in wind speed at two elevations causes the wind shear
2. The difference in wind speed causes a column of air to rotate horizontally
3. A strong updraft connects the rotating air with clouds above
4. The column of air stretches to form a tornado
Explanation
The typical steps of tornado formation follow the below steps;
• Occurrence of a large thunderstorm which happens in the cumulonimbus clouds
• There is a change in wind direction and speed at higher attitudes that makes the air to swirl horizontally
• Air rising from the ground pushes up on the swirling air and tips over it
• The swirling air funnel starts to suck up more warm air from the ground
• The funnel enlarges and stretches towards the ground
• The funnel touches the ground level to form a tornado
Answer:
Explanation:
We are given that
Charged on alpha particle=q=2e=
Where 
Initial kinetic energy=K.E=5.76 MeV=
Z=79
Charge on protons=
We have to find the closeness of alpha particle to the gold nucleus before being turned around.
Initial kinetic energy=Final potential energy
Where 
If Your Somewhere Different .
